EEMC-MAC: An Energy Efficient Protocol for Multi-Channel Wireless Networks
Thiago Fernandes Neves, Jacir Luiz BORDIM · 2013
Abstract—The popularization of wireless network technologies has driven the quest for efficient solutions in the use of the available resources. In particular, there is an increasing demand for solutions to reduce energy consumption and improve spectrum use. In this context, this work addresses the problems of energy efficient multi-channel assignment and communication scheduling in wireless networks. Considering that the channel allocation is an NP-complete problem, this paper presents a time and energy-efficient protocol. The protocol divides its operation in management and transmission stages. Empirical results show that the management stage, in average, takes less than 5 % from the total protocol execution time, while the transmission stage is optimum in terms of energy consumption. Keywords—wireless networks; energy efficient protocols; multi-channel assignment; scheduling. I.
