Destination-Sequenced Distance Vector Protocol (DSDV) is a proactive protocols available in Ad-Hoc mobile network where this protocol is not suitable for use on networks with high mobility because DSDV needs to update routing tables regularly if there is a link between nodes that is disconnected because there are nodes that move out of the transmission signal range and the AODV protocol is a protocol that matches high mobility because it is reactive. So that in a stable route search can be done by selecting a route that has a small chance of being interrupted. LET algorithm is used in the DSDV protocol to find the most stable route by knowing the estimated time between two nodes to remain connected based on the position, speed and range of the transmission signal then compared with the AODV routing protocol based on parameters such as throughput, packet delivery ratio and delay. The results showed that the S-DSDV routing protocol has better performance than the standard DSDV routing protocol. Key words : DSDV, Link Expiration Time, AODV, MANET, Routing Protocol

Ad-hoc network is a network of moving wireless nodes which do not have a central or permanent influence over their connections. It is a mobile node device that is auto configured and connected to an arbitrary infrastructure through wireless connections. Therefore, due to the highly complex environment, MANET routing is acrucial activity. Various protocols are used to enhance the routing process, such that a network route is found between every transmitter and the host receiver. In this post, we modified the AODV protocol to increase the rate of throughput, end-to-end delays, and packet distribution, etc. We used ns3 simulator to compare the protocols AODV, DSDV, OLSR and Enhanced AODV. It is noteworthy that EAODV routing protocols perform much better than OLSR that the DSDV routing protocol provides high throughput, a lower latency and high delivery ratio of packages. In addition, our proposed energy efficient model has changed conventional AODV. Our improved EAODV protocol's overall performance is 3% superior to other conventional protocols.

Wireless networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology; thus the need for a robust dynamic routing protocol that can accommodate such an environment. To improve the packet delivery ratio of Destination-Sequenced Distance Vector (DSDV) routing protocol in mobile ad hoc networks with high mobility, a message exchange scheme for its invalid route reconstruction is being used. Two protocols AODV and DSDV simulated using NS-2 package and were compared in terms throughput, end to end delay and packet faction delivery varying number of nodes, speed and time. Simulation results show that DSDV compared with AODV, DSDV routing protocol consumes more bandwidth, because of the frequent broadcasting of routing updates. While the AODV is better than DSDV as it doesn’t maintain any routing tables at nodes which results in less overhead and more bandwidth. AODV perform better under high mobility simulations than DSDV. High mobility results in frequent link failures and the overhead involved in updating all the nodes with the new routing information as in DSDV is much more than that involved AODV, where the routes are created as and when required. AODV use on -demand route discovery, but with different routing mechanics. AODV uses routing tables, one route per destination, and destination sequence numbers,

Effective disaster management is required for the peoples who are trapped in the disaster scenario but unfortunately when disaster situation occurs the infrastructure support is no longer available to the rescue team. Ad hoc networks which are infrastructure-less networks can easily deploy in such situation. In disaster area mobility model, disaster area is divided into different zones such as incident zone, casualty treatment zones, transport areas, hospital zones, etc. Also, in order to tackle high mobility of nodes and frequent failure of links in a network, there is a need of adaptive routing protocol. Reinforcement learning is used to design such adaptive routing protocol which shows good improvement in packet delivery ratio, delay and average energy consumed.

Networking Technology

Recently, the flying ad-hoc network (FANETs) is a popular networking technology used to create a wireless network through unmanned aerial vehicles (UAVs). In this network, the UAV nodes work as intermediate nodes that communicate with each other to transmit data packets over the network, in the absence of fixed an infrastructure. Due to high mobility degree of UAV nodes, network formation and deformation among the UAVs are very frequent. Therefore, effective routing is a more challenging issue in FANETs. This paper presents performance evaluations and comparisons of the popular topology-based routing protocol namely AODV and position-based routing protocol, namely LAR for high speed mobility as well as a verity of the density of UAV nodes in the FANETs environment through NS-2 simulator. The extensive simulation results have shown that LAR gives better performance than AODV significantly in terms of the packet delivery ratio, normalized routing overhead, end-to-end delay, and average throughput, which make it a more effective routing protocol for the highly dynamic nature of FANETs.

In mobile ad hoc wireless networks (MANETs), traditional protocol like AODV performs well for low mobility of nodes but not for high node mobility. So, it becomes important to consider mobility factor during the path selection procedure of routing protocol. Here, a fuzzy logic mobility based protocol (FLM-AODV) that considers the mobility factor is proposed. Due to the consideration of mobility factor, the proposed protocol has better performance than the traditional AODV. The experiment results show that the proposed protocol has advantages of improved average end-to-end delay and packet delivery ratio (PDR) over existing AODV protocol.

Mobile ad hoc networks (MANETs) can be defined as a collection of large number of mobile nodes that form temporary network without aid of any existing network infrastructure or central access point. The Efficient routing protocols can provide significant benefits to mobile ad hoc networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. The main method for evaluating the performance of MANETs is simulation. The Network Simulator is a discrete event driven simulator. The goal of ns-2 is to support networking ,research, and education. In this paper we create a new Routing Protocol called My Router step by step in Ns-2.Then we evaluate its performance based on several parameters such as Packet Delivery Ratio , End to End Delay etc and compare it with MANET routing protocol OLSR .

Reduce Energy Consumption

An ad hoc network is a dynamically wireless mobile network. It can construct network automatically and quickly. Because of the importance and universality of application, ad hoc network is trend to become a research hotspot. It is necessary to research an effective routing protocol so as to be adapted to mobility of terminal equipment and to provide the reliable data transmission. This paper firstly studied and analyzed existed routing protocols, and simulated these protocols. Finally we proposed an improved routing protocol based on DSR and AODV, in which we divided all nodes into different clusters, and every cluster has only one cluster head. These nodes within the same cluster communicate using DSR protocol while those nodes in the different cluster communicate through the cluster head using AODV protocol. So, the data packet can go through the shortest link, thus it can decrease transmission delay and reduce energy consumption remarkably. Finally we use the network simulation software named NS2 to simulate experiment result. The results show that this protocol can improve the performance and the service quality of the network.

Mobile Ad Hoc

Mobile Ad-hoc Network (MANET) is a dynamic wireless network without any infrastructures. The network is weak and vulnerable to many types of attacks. One of these attacks is BlackHole. In this attack, a malicious node advertises itself as having a high sequence number and a shortest path to a specific node to absorb packets. The effect of BlackHole attack on ad-hoc network using AODV as a routing protocol will be examined in this research. We also propose a new mechanism, called DPBA-AODV, to detect and prevent BlackHole attacks on AODV protocol. Simulation result, by using NS2, depicts the efficiency of our proposed mechanism in packet delivery ratio under the presence of BlackHole nodes.

Route Request

A Mobile Ad Hoc Network (MANET) protocol requires proper settings to perform data transmission optimally. To overcome this problem, it is necessary to select the correct routing protocol and use the routing protocol’s default parameter values. This study examined the effect of route request parameters, such as RREQ_RETRIES and MAX_RREQ_TIMOUT, on the Ad Hoc On-demand Distance Vector (AODV) protocol, which was then compared with the default AODV performance Optimized Link State Routing (OLSR) protocols. The performance metrics used for measuring performance were Packet Delivery Ratio (PDR), throughput, delay, packet loss, energy consumption, and routing overhead. The results show that the OLSR protocol has a smaller delay than the AODV protocol, while in other measurements, the AODV protocol is better than OLSR. By reducing the combination value of RREQ_RETRIES, MAX_RREQ_TIMEOUT in AODV routing to (2, 10 s) and (3, 5 s), the protocol’s performance can be improved. The two combinations result in an average increase in throughput performance of 3.09%, a decrease in delay of 17.7%, a decrease in packet loss of 27.15%, and an increase in PDR of 4.8%. For variations in the speed of movement of nodes, 20 m/s has the best performance, while 5 m/s has the worst performance.

Video streaming is content sent in compressed form over the netwoks and viwed the users progressively. The transmission of video with the end goal that it can be prepared as consistent and nonstop stream. The point is that to give client support to client at anyplace and at whatever time. Mobile Ad hoc Networks (MANETs) are considered an attractive nertwork for information transmission in many applications where the customer programme can begin showing the information before the whole record has been transmitted. Ad hoc On-demand Distance Vector (AODV) protocol is considered as one of the most important routing protocols in MANET. However, routing protocols assume a crucial part in transmission of information over the network. This paper investigates the performance of AODV Routing Protocol under video traffic over PHY IEEE 802.11g. The protocol model was developed in OPNET. Different outcomes from simulation based models are analyzed and appropriate reasons are also discussed. A different scenarios of video streaming were used. The metric in terms of throughput, end to end delay, packet delivery ratio and routing overhead were measured. A comparision with GRP and GRP are also reported.
