Energy efficient neighbor coverage-based probabilistic rebroadcasting in MANET

Abstract

Mobile Ad hoc network is a communication network build with limited resource without any fixed infrastructure. Broadcasting mechanism is used to build a structure and maintain a virtual infrastructure for communications. Methods and algorithms have already proposed with the objective to overcome the challenges of MANET. Still there is need of developing an efficient broadcasting model due to the bottlenecks of existing systems. This paper proposes an enhanced rebroadcasting algorithm where the decision of rebroadcasting was made for the next level neighbor nodes with immediate or wait state. This approach helps in increasing the speed to cover unreached nodes in a network and reduces number of rebroadcast in the network. This in turn reduces the energy consumption in a network. Simulation results of the proposed approach were analyzed and compared with the existing works. Results prove that the proposed work has higher packet delivery ratio of an average 99.964 percentage for different pause times. It has also reduced the energy consumption of the network to an average of 0.0617 joules for the experimented scenario. Delay in packet transactions by the proposed algorithm was observed to be reduced to an average of 0.00634 ms in the network.
