Advances in network technology have encouraged the development of ad-hoc services. MANET is one of them. In MANET, a routing protocol is required that can facilitate communication reliably. To get this reliable routing, in this study simulation of two routing protocols, namely AODV and OLSR. In the Manhattan Grid Mobility (MGM) model with communication loads using the FTP protocol. The simulation results show that the end-to-end value of service quality is 0.00210 second and throughput of 0.353428 Mbps for high FTP load in AODV routing. While the OLSR protocol routing obtained end to end delay value is 0.00071 second and throughput of 0.532025 Mbps for high load load FTP. For high load FTP traffic loads, 0.042436 second response time upload and 0.085789 second time response download on AODV protocol routing. On the OLSR routing protocol the upload time response rate is 0.084756 second response time and 0.09271 seconds download time response.

Improved Performance

RPL (IPv6 Routing Protocol for Low-Power and Lossy Net- works) was developed by IETF (Internet Engineering Task Force) as the protocol for LLNs (low power and lossy networks) that comprise of resource constrained components such as those used in Internet of Things applications. Since then the research community and the industry have come up with many enhancements of RPL aimed at achieving a diverse range of objectives that include better performance under heavy traffic loads, higher throughput, lower packet loss, energy conservation, longer network lifetime, mobility of nodes and enhanced security. This paper presents a review of the various methods proposed to achieve these objectives. A comparative review and a taxonomy of these methods are presented in this paper. We aim to provide valuable insights into RPL and present the foundation for future works.

Vehicular Ad Hoc Networks (VANETs) is the most growing research area in wireless communication and has been gaining significant attention over recent years due to its role in designing intelligent transportation systems. Wireless multi-hop forwarding in VANETs is challenging since the data has to be relayed as soon as possible through the intermediate vehicles from the source to destination. This paper proposes a modified fuzzy-based greedy routing protocol (MFGR) which is an enhanced version of fuzzy logic-based greedy routing protocol (FLGR). Our proposed protocol applies fuzzy logic for the selection of the next greedy forwarder to forward the data reliably towards the destination. Five parameters, namely distance, direction, speed, position, and trust have been used to evaluate the node’s stability using fuzzy logic. The simulation results demonstrate that the proposed MFGR scheme can achieve the best performance in terms of the highest packet delivery ratio (PDR) and minimizes the average number of hops among all protocols.

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.
