Abstract

A routing protocol is used to determine the optimal path to forward the packets from source to destination. A separate set of protocols is designed for IPv4&IPv6 network such as RIP, OSPF-v2, RIPng, OSPF-v3, and AODV. IPv4 is replaced by IPv6 (next generation internet protocol), but both the protocols are not suitable for each other, due to this they need to coexist for a long time. In this paper, the performance is evaluated for different routing protocols for IPv4 and IPv6 over wired, wireless and the hybrid network. Simulations are carried out on EXata/Cyber 2.1 Simulator/Emulator. The performance of routing protocols is measured on the basis of throughput, jitter, end-to-end delay and packet delivery ratio (PDR). By the simulation, on the basis of throughput and PDR performance of AODV (IPv4) is very good as compared with other routing protocols. It has been observed that due to the size of the IPv6 header, which is larger than IPv4 header the performance of routing protocols downgrades.

Abstract

MANETs are very advantageous and fruitful when there is no infrastructure or has been destroyed due to some reasons like earthquake, floods and so on. Data communication in MANETs are very challenging issue due to threats like limited battery power, limited bandwidth, mobility, routing and QoS and so on. Due to these challenges and scarcity of resources in MANETs, it's very difficult to achieve high quality of service. QAODV, AODV, OLSR, DSDV and ZRP and so on, are some of very popular routing protocols for MANETs. Minimum no. of hops is the route selection criteria used by most of the routing protocols. This makes it necessary to consider QoS parameters to the routing protocols. Above mentioned protocols are not pure QoS routing protocol and insufficient to achieve high Qos because they do not consider parameters which will affect the QoS, Instead they only consider hop count as a route selection criteria. We present a new QoS based routing algorithm AODV-QSRP (AODV based QoS Routing Protocol) for Mobile Adhoc Netwok. AODV-QSRP is based on existing AODV and is reactive (On-Demand) in nature. AODV-QSRP attempts to provide high QoS for the real time applications while considering the various important QoS parameters like Bandwidth, Delay, Link Quality and Battery power for route selection. We have simulated and compared the performance of AODV-QSRP with QAODV, AODV, OLSR, DSDV and ZRP. To implement and simulating the result Network Simulator-2 (NS-2.32) on Fedora platform is used, which is an event driven and real-time simulator.

Abstract

In today's life, Wireless Networks (WNs) are being used very fast in every area. They have been used in various applications, but finding some of the weaknesses, such as mobility, diversity, lack of resources and so on, finding an optimum route is very complex and problematic. By reducing the energy consumption on each node, the quality of the network can be ensured. Need to increase the battery life of the node to increase the network lifecycle. Therefore, reducing energy consumption can extend the battery life of the node. There is a fundamental research issue for finding and maintaining routes between multi-path routing nodes. This paper discusses routing protocols based on Zone Technology, which uses the energy, distance, and power of the node to maintain high circulation and accelerate the path search process and maintain high search. Zone-based Leader Election Routing Protocol (ZBLE) is one of the new protocols, which is a modified form of AOMDV. The Zone Leader Node and Zone Members are selected using the value of energy, position, and power of the node. The performance of the proposed communication protocol is evaluated with other existing protocols such as AODV and AOMDV. The simulation result is that when it receives the best path for data communication with proper energy conservation. Network simulator version 2.35 is used for simulation purpose. To support our ideas, we used the 5 quality of service parameters such as packet distribution ratio, energy consumption, network lifetime, and throughput.
