Since the quick topology change and short connection duration, the VANET has had unstable routing and wireless signal quality. This paper proposes a kind of lightweight routing protocol-LNIB for call system without base station, which is applicable to the urban taxis. LNIB maintains and predicts neighbor information dynamically, thus finding the reliable path between the source and the target. This paper describes the protocol in detail and evaluates the performance of this protocol by simulating under different nodes density and speed. The result of evaluation shows that the performance of LNIB is better than AODV which is a classic protocol in taxi-call scene.

Mobile adhoc networks (MANET) are a self-coordinated wireless network that is worked without perpetual foundation and base station endorsement. In MANETs (Mobile Ad Hoc Networks) every single node activity goes about as the information source and communicator router. It notices its useful neighbours by making themselves by passing the nodes that got terminated of that correspondence range. In this paper, we designed the IHRP routing protocol with the help of combining the AODV, AOMDV and OLSR routing protocol with the network situation based routing adaptation. In the previous analysis, we identify AODV is more compatible for dynamic environment (where node motion is higher).The AOMDV routing protocol is useful for network load balancing and congestion control. OLSR is compatible for stable network which use as maximum link stability base routing. While we are designing the IHRP routing protocol through of the above (AODV, AOMDV and OLSR) protocol .We handle the network behaviour with better performance in any situation. Initially the RREP are broadcasted to find out the route. The poll of routing, select based on the network situation. The proposed IHRP start with a RREQ packet is to search the distance from its origin to its objective node. The network motion is higher than AODV protocol handle the particular situation but in any situation, while the 70% network node are stable then the route selection and transferring of data with the help of an OLSR routing protocol. The propose IHRP routing protocol also handle the network load and control the network congestion through the AOMDV routing protocol. Our proposed protocol IHRP also works in a hybrid manner while the source and destination belong in longer range such as different cluster. At that time situation based routing was followed between the clusters. We saw in the result part the comparison of IHRP and ZRP routing protocol. Execution of the improved hybrid routing protocol (IHRP) is much better than hybrid routing protocol (ZRP). In case of Packet Delivery Ratio analysis for IHRP and ZRP, we clearly show that The Packet Delivery Ratio is 97.99% by IHRP and 79.49% by ZRP, so we can say that the performance of packet delivery ratio in Improved hybrid routing protocol (IHRP) is much better than ZRP, where Improved hybrid routing protocol (IHRP) and hybrid routing protocol (ZRP) both performed the conjunction of proactive and reactive routing protocol features therefore we can say that Packet Delivery Ratio is better in improved hybrid routing protocol (IHRP) as compare to hybrid routing protocol (ZRP). We clearly show that the Normal Routing Load analysis for IHRP and ZRP where Normal Routing Load is 0.11% by IHRP and 4.72 % by ZRP, so we can say that performance of Improved Hybrid Routing Protocol (IHRP) in case of a Normal Routing Load   is much less than the Hybrid Routing Protocol (ZRP). In case of overall parameter matrix (Normal Routing Load, Throughput, Packet Delivery Ratio and Average End To End Delay) the performance of Improved Hybrid Routing Protocol (IHRP) is much better than existing Hybrid routing protocol (ZRP).

Cluster Based Routing

Now days, wireless technology is one of the center of attention for users and researchers. Wireless network is a network having large number of sensor nodes and hence called as “Wireless Sensor Network (WSN)”. WSN monitors and senses the environment of targeted area. The sensor nodes in WSN transmit data to the base station depending on the application. These sensor nodes communicate with each other and routing is selected on the basis of routing protocols which are application specific. Based on network structure, routing protocols in WSN can be divided into two categories: flat routing, hierarchical or cluster based routing, location based routing. Out of these, hierarchical or cluster based routing is becoming an active branch of routing technology in WSN. To allow base station to receive unaltered or original data, routing protocol should be energy-efficient and secure. To fulfill this, Hierarchical or Cluster base routing protocol for WSN is the most energy-efficient among other routing protocols. Hence, in this paper, we present a survey on different hierarchical clustered routing techniques for WSN. We also present the key management schemes to provide security in WSN. Further we study and compare secure hierarchical routing protocols based on various criteria.

Heterogeneous Sensor Network

Wireless sensor networks (WSN) are networks of thousands of nodes installed in a defined physical environment to sense and monitor its state condition. The viability of such a network is directly dependent and limited by the power of batteries supplying the nodes of these networks, which represents a disadvantage of such a network. To improve and extend the life of WSNs, scientists around the world regularly develop various routing protocols that minimize and optimize the energy consumption of sensor network nodes. This article, introduces a new heterogeneous-aware routing protocol well known as Extended Z-SEP Routing Protocol with Hierarchical Clustering Approach for Wireless Heterogeneous Sensor Network or EZ-SEP, where the connection of nodes to a base station (BS) is done via a hybrid method, i.e., a certain amount of nodes communicate with the base station directly, while the remaining ones form a cluster to transfer data. Parameters of the field are unknown, and the field is partitioned into zones depending on the node energy. We reviewed the Z-SEP protocol concerning the election of the cluster head (CH) and its communication with BS and presented a novel extended mechanism for the selection of the CH based on remaining residual energy. In addition, EZ-SEP is weighted up using various estimation schemes such as base station repositioning, altering the field density, and variable nodes energy for comparison with the previous parent algorithm. EZ-SEP was executed and compared to routing protocols such as Z-SEP, SEP, and LEACH. The proposed algorithm performed using the MATLAB R2016b simulator. Simulation results show that our proposed extended version performs better than Z-SEP in the stability period due to an increase in the number of active nodes by 48%, in efficiency of network by the high packet delivery coefficient by 16% and optimizes the average power consumption compared to by 34.

Simulation environment of the mobile Ad Hoc network is built by applying NS2 simulation software. The simulation data indicates that AODV routing protocol is better than DSDV in throughput, fairness and stability. In the underwater network environment where the nodes are in Low-Speed movement, the data transfer rate of AODV routing protocol is higher than AOMDV. To a certain extent, AODV is more suitable for application in underwater environments.

MANET supports communication without any wired medium and with layered architecture. It does not uses any infrastructure support. Present alternative to the layered architecture is cross layer design approaches and the interaction between the layers is supported. The security of CLPC (Cross Layer Design Approach for Power control) routing protocol will be discussed in this paper. The transmission power and finding the effective route between source and destination can be improved by CLPC. The reliable path between the source and destination can be determined by RSS from the physical layer, but it is vulnerable to the DOS attacks. Here we propose a Secure cross layer power control protocol SCLPC to placate the attacks on CLPC. The SCLPC protocol provides better results and performance.

Internet of Things, abbreviated as IoT is a network used mainly for the communication where different devices are connected for the retrieval, examination and execution of the necessary task. One of IoT’s biggest challenge is that, they are resource-constrained. Hence, it is essential to use an efficient data transmission protocol for routing. An effective routing protocol for static IoT network is the Routing protocol for Low Power and Lossy Networks (RPL). It is essential to assess the effectiveness of the RPL with the selection of best objective function for different static model. In this paper, the performance of different routing algorithms is compared in connection with different static topologies. Hence, the objective function’s performance is compared for different topologies i.e., Butterfly, Ring and Umbrella topologies. We consider two objective functions: namely Minimum Rank with Hysteresis Objective Function (MRHOF) and Objective Function Zero (OF0). MRHOF considers Expected Transmission Count (ETX) as its metric and the metric considered under OF0 is hop count. It is observed that the objective function OF0 performs better than MRHOF for the metric of energy and successful receiving of data.

ABSTRAKOSPF (Open Shortest Path First) adalah suatu routing protokol bersifat terbuka dan didukung oleh berbagai perangkat network. IPv4 telah mencapai batas maksimum dalam jumlah alamat sehingga IPv6 merupakan solusi dalam hal tersebut. Seperti IPv4, IPv6 juga sudah mulai diimplementasikan untuk routing protokol OSPF, oleh karena itu pada penelitian ini akan dirancang suatu routing protokol OSPF IPv6 dan sebagai bahan perbandingan akan dibandingkan dengan OSPF IPv4. Software Cisco Packet Tracer 5.3 digunakan untuk mensimulasikan perancangan jaringan yang dibuat. Pada penelitian ini akan dibandingkan 2 buah jaringan berbasis routing protokol OSPF, yaitu OSPF untuk IPv4 dan IPv6. Skenario pertama dilakukan 100 kali dalam 5 kasus untuk mengetahui nilai delay OSPF IPv4 dan OSPF IPv6. Skenario kedua dilakukan pemutusan link dilakukan sebanyak 30 kali, hal yang dilihat dari pengujian ini adalah hasil trace route dari cost yang ada. Skenario ketiga dilakukan dengan mengamati waktu konvergensi dari OSPF IPv4 dan IPv6. Secara keseluruhan nilai delay OSPF IPv6 lebih kecil dibandingkan dengan OSPF IPv4 sebesar 3-6%, Trace route dan nilai cost pada OSPF IPv6 dan OSPF IPv4 sama tetapi nilai delay OSPF IPv6 lebih kecil sebesar 3-6% dan waktu konvergensi OSPF IPv4 bernilai sama dengan OSPF IPv6 yaitu 10 detik.Kata kunci: OSPF, IPv4, Ipv6, delay, konvergensiABSTRACTOSPF (Open Shortest Path First) is a routing protocol that opened and supported by a wide range of network devices. IPv4 has reached the maximum limit on the number of addresses that IPv6 are a solution in this case. Same as IPv4, IPv6 also has begun to be implemented for the OSPF routing protocol, therefore this study wiould design an IPv6 OSPF routing protocol and as a comparison will be compared to IPv4 OSPF. Cisco Packet Tracer 5.3 software was used to simulate the made network design. This research would compare two pieces of network-based routing protocol OSPF, OSPF for IPv4 and IPv6.

In recent times, petroleum pipeline vandalism resulting into spillage has become a significant challenge in Nigeria. Citizens are regularly inundated with reported cases of vandalism which often lead to spillage and a drastic reduction in government’s revenue as is currently the case in Nigeria. This paper focuses on the design of petroleum pipeline spillage detection system. The design consists of the power supply unit, the comparator unit, the microcontroller unit, the switching unit, the transceiver unit and the base station. Simulation of the various units was done individually using the procedural programming application Proteus 8. Most of the components used were according to design specifications from data book with alternatives used in cases where they are unavailable. Wiring sensors which provided continuous electrical paths to break the signal path and trigger an alarm at the base station were used The design was done in units and were tested individually and the whole system was tested to perform the required task of detecting petroleum spillage and alerting the control room for action. It is found that the designed system had the advantage of responding to intrusion and vandalism better than existing systems.
