Cooperative Residual Battery (CORB) Resource Optimization in AODV Routing Protocol

Abstract

In Ad-hoc network minimizing the energy utilization is one of the core issues in transmission of data with entail quality of service. Cooperative communication networks have been recently being studied as an alternative to MIMO wireless networks where cooperation between source destination and relay are considered. In this paper, Cooperative Residual Battery (CORB) Resource Optimization routing protocol is proposed in which the route formation in cooperative network from source to destination is established by selecting the minimum battery consuming node as relay. Packet reception ratio is considered for efficiently switching between the direct communication and cooperative communication depending on the type of scenario’s that occur in real time. The proposed work is based on the modification done on AODV protocol. The relay selection in cooperative communication is established based on least hop count and residual battery life of a node. The protocol is mainly based on selecting a helper node from a list of intermediate nodes that are consuming less energy to forward the data on to the destination. Considerable modification in Route request and Route reply packet is done in order to carry the Residual battery information of nodes that are handling the Control packets (RREQ & RREP), along with the control packets, routing table is modified for managing the routing information. Simulation is carried out to assess the essence of the protocol proposed.
