A Network Lifetime Extension-aware Cooperative Mac Protocol For Manets With Optimized Power Control

A Network Lifetime Extension-Aware Cooperative MAC Protocol for MANETs with Optimized Power Control

Abstract:

In this, a cooperative medium access control (CMAC) protocol, termed network lifetime Extension-aware CMAC for mobile ad-hoc networks is proposed. The main feature of the LEA-CMAC protocol is to enhance the network performance through the cooperative transmission to achieve a multi-objective target orientation. The unpredictable nature of wireless communication links results in the degradation of network performance in terms of throughput, end-to-end delay, energy potency, and network lifetime of MANETs. Through cooperative transmission, the network performance of MANETs can be improved, providing a helpful cooperation is satisfied and design parameters are fastidiously elected at the Mac layer. To achieve a multi-objective target-oriented CMAC protocol, we formulated an optimization problem to extend the network lifetime of MANETs. The optimization solution led to the investigation of Symmetric and asymmetric transmit power policies. We then projected a distributed relay choice method to select the simplest retransmitting node among the qualified relays, considerately on a transmit power, an adequate residual energy when cooperation, and a high cooperative gain. The simulation results show that the LEA-CMAC protocol can do a multi-objective target orientation by exploiting an asymmetric transmit power policy to improve the network performance.
