Load and Energy Aware Adaptive Zone Routing Protocol for MANET

Abstract

In Mobile Ad Hoc Networks (MANET), during zone based routing, the zone radius should be adaptively varied depending on the overhead, energy consumption and packet reception rate. The load of the border nodules needs to be considered. This research work proposes  Load and Energy Aware Adaptive Zone Routing Protocol (LEA-AZRP). In this protocol, zone leader is selected based on the nodule load. Then the proactive routing is applied within each zone and reactive or on-demand route discovery is applied across the zones. The zone radius is adjusted depending on the packet reception rate and data delivery time. Based on the relative mobility of the nodule, load and residual energy, the zone leader selection and zone construction are processed. By simulation results, it will be shown that the LEA-AZRP achieves higher throughput with reduced energy consumption.
