An Enhanced Energy Efficient Hybrid Asynchronous Duty Cycle MAC in Wireless Sensor

Abstract

Abstract Wireless sensor network (WSN) has countless potential application in many areas due to its easy deployment process, lower installation cost, less cabling required, and high mobility. However, limited energy residue (especially deposited in small size battery) is always a major obstacle in WSN. Improving mechanism on MAC layer is one of the potential research that could increase battery lifespan. In the active phase of the MAC layer, a node can receive and transmit packet when awake. Then, a node is in a sleep phase, it switches off the radio automatically to save energy and gives alert. While in idle listening phase, node still using the energy. Duty cycling performed in MAC layer don’t involve turning off their radio and switching sleep mode but repeating off/on process. Therefore, this study proposed mechanism of WSN that used in order to enhance power energy using duty cycle in MAC layer. The proposed of asynchronous duty cycle MAC layer using a hybrid duty cycle MAC in implementation the performance of WSN. In addition, this paper also elaborated the design asynchronous hybrid duty cycle MAC with multi-hop broadcast.
