Efficient Routing Based on Core Relay Intermediate Nodes in MANET

Abstract

Efficient routing in mobile ad hoc network (MANET) is necessary for effective data communication among nodes. Routing can be done either singlehop or multi-hop. If source and destination are within the transmission range then single-hop routing is established, else multi-hop routing is required to route the data packets to reach the destination. Selection of next hop based on the speed of movement of nodes and transmission range: reduces overall energy consumption, link failures and delay constraints. The weights of the link quality between the nodes present in the network can be estimated by cost metrics such as distance and travelling speed of the node. The success of the data transmission via core relay intermediate nodes (CRIN) can be analysed using NS-2 tool. The efficiency of 0.4% is improved by the proposed scheme. Network performance can be enhanced through shortest path so that messages may be delivered in a timely manner.
