Abstract

To achieve high protocol efficiency is one of the primary goals in designing routing protocols for mobile ad hoc networks (MANETs), because high protocol efficiency implies low additional control overhead and power cost, which are two key issues in MANETs due to the inherited bandwidth and power-constrained characteristic. In this paper, an AODV improvement protocol with the Hello message mechanism is presented based on wireless link availability prediction. The simulation results demonstrate that the improved AODV improves the performance in terms of latency and protocol efficiency greatly, compared to the standard AODV with the periodic Hello message broadcast mechanism.
