Multilayer MAC with Adaptive listening for WSN

Abstract

In general, WSN refers to a group of nodes that is deployed to monitor a particular environment. The nodes are usually wireless sensors that maintain high energy to enhance the network lifetime. The energy of a node will be wasted if the node keeps on working throughout the simulation time or even when it has no packets. This paper presents two innovative approaches for MAC. They are (1) Mathematical Modeling in MAC and (2) MAC with Relay Nodes. We proposed a new technique for MAC with a multilayer approach. In this paper, a MAC with and without multilayer is simulated using NS-2.35. SMAC approach integrated with adaptive listening in the sleep and idle states for the nodes will leverage a better energy efficiency and throughput. The final result shows that the ML-MAC is the suitable method for WSN applications.
