Evaluation of Energy Efficient Reactive Routing Protocols in QoS Enabled Routing for MANETS
نویسنده
چکیده
A mobile node has a finite and decreasing energy. When finding routes, energy aware routing increases the network lifetime. Energy saving mechanism is required for the efficient operation of the battery powered network. In general, all the neighboring nodes overhear transmission when a node is transmitting a packet. Overhearing is caused by receiving information that is not addressed to it. Energy consumed by overhearing nodes is same as that of receiving nodes. The main aim of this work is to develop an energy conserving mechanism to reduce energy expenditure due to overhearing. To minimize energy, number of overhearing nodes is randomly selected based on probability. This probability based overhearing is integrated with AODV routing protocol. This proposed approach is implemented in NS2 simulator. Simulation results are presented to demonstrate the performance metrics such as throughput, packet delivery ratio, end-end delay and energy consumption of the network.
