Improving Node Selection using Modified Multipath Routing Protocol in MANET

Abstract

Internet connection always and everywhere despite the geographical position is provided by designing the Mobile ad hoc network (MANET). The disaster recovery, military, as well as environment monitoring are included within the applications of MANET. The communication processes are quite difficult for Resource-constrained environment of MANET. The limited batteries are the equipment used for the network nodes and replacing as well as recharging the batteries is quite challenging in the throughout the mission. Regardless of the circumstances, the nodes are added within the MANET and reliable as well as trustworthy methods must be present for performing the communication between the nodes. Trustworthiness is defined as the node’s point of view upon the other node and the representation is done numerically. Upon the basis of the earlier communication among the presented nodes, the calculation of the trust is done. Therefore, a modified multipath routing technique is required for addressing the limitations. Since the MANET is a peer-to-peer network and is an Infrastructureless network, the energy effectiveness is achieved with the help of the network layer. A modified multipath routing protocol is developed. Depending upon the present residual condition of the network nodes, the selection of the routing path is done. It is concluded by the simulation results that compared to the existing methods such as E-AODV, MRPC in terms of the lifetime of the network as well as the stability of the network, the proposed method performs effectively. Simulation results through NS2 software to verify the effectiveness of our method.
