Optimized Medium Access Control for Wireless Sensornetwork & Its Performance Analysis

Most of medium access control (MAC) protocols proposed for wireless sensor networks (WSN)are targeted only for single main objective, the energy efficiency. critical parameters such as bandwidth utilization, low-latency,, scalability, and fairness, are treated as secondary objectives. In this paper, it is focused on the Medium Access Control (MAC) layer in WSNs & an Optimized MAC scheme, for WSNs is proposed that extends lifetime of the network. This MAC protocol will solve energy inefficiency considering nodes latency based on network traffic and increases Packet delivery ratio. It will achieve high energy efficiency for large range of traffic loads and is able to adopt itself for improving the delay performance when network traffic load is high. Simulation experiments have been performed to demonstrate usefulness of proposed scheme
