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 de- mand for solutions to reduce energy consumption and improve channel use. This work addresses the problems of multi-channel assignment and communication scheduling in wireless networks. Considering that channel allocation is a NP-complete problem, this paper presents a time and energy-efficient heuristic to tackle the multi-channel assignment problem. Once channel assignment is performed, an energy-efficient protocol allows the stations to complete their data transfers using minimum resources. The protocol divides its operation in management and transmission stages. The main contribution of this work is to present a multi-channel communication protocol that efficiently reduces communication time by exploring multiple channels even for control messages. Empirical results show that the management stage takes, in average, less than 9% from the protocol total time while the transmission stage, in average, takes only 5% more time than the optimum time.
