Energy Efficient with Collision Free MAC Protocol for Wireless Sensor Network

Abstract

In modern networks, a Wireless Sensor Network (WSN) is distributed far and wide to monitor physical or environmental situations. In WSNs, the Medium Access Control (MAC) protocol is greatly affected in energy consumption of sensor nodes by controlling the node radio functionalities. Many MAC protocols have been successfully designed towards the prime objective of energy efficiency. However, the classical layered protocols are mostly based on the existing solutions, which lead to significant overhead. This paper mainly contributes towards developing MAC protocol that considers energy consumption, packet delay, packet delivery, traffic adaptability, and many others for nodes in wireless networks. The simulation results and analysis illustrate that the proposed MAC protocol outperforms the contention-based and scheduling-based MAC protocols in terms of packet delivery ratio, network lifetime, delivery delay to the BS and energy consumption for various traffic loads in the network.
