Abstract

According to wireless Ad hoc networks being able to adjust transmission rate, this paper studies the rate adaptation for network lifetime maximization. The problem is formulated as a mixed integer nonlinear programming, which can be solved using branch and bound methods. Further, a greedy distributed Maximizing Network Lifetime Rate Adaptation Algorithm (MNLRAA) is present. MNLRAA tries to selects the lower transmission rates for each link based on the traffic and the remaining energy at nodes so as to reduce energy consumption. The simulation results show that MNLRAA can improve more than 20% the network lifetime than the classic technique that all nodes transmit packet with the highest rate.
