Abstract
Objectives: To propose power control techniques used in MAC protocol for wireless networks. Methods/Statistical Analysis: Energy reductions techniques are essential for wireless networks, as battery powered wireless hosts have limited energy. Hence energy aware techniques with power saving mechanisms are restored to conserve energy of nodes in wireless networks. Power based connectivity is an ad-hoc implements power control mechanisms to enhance network life by improving throughput, cost effective routes and spatial reuse. This study proposes hybrid optimization for “Medium Access Control (MAC)” protocol to implement coordination functions and power control mechanisms. Hybrid optimization is based on “Genetic Algorithm (GA)” and “Gravitational Search Algorithm (GSA)”. Findings: Experiments with hybrid optimization are compared to GA fuzzy rules and Fuzzy methods. The result reveal that two hop power control with GA fuzzy logic method lowers route discovery time, increases cache replies, minimizes simulation time and end to end delay in contrast to DSR routing and two hop routing protocols. Application/Improvements: The new hybrid GA-GSA has a throughput of 8.89% and 1.62% and low end to end delay of 13.66% and 2% compared to Fuzzy and GA based Fuzzy respectively.
