Energy Efficient Multi Channel MAC Protocols for Wireless Ad Hoc Networks

Wireless ad-hoc networks are expected to support a variety of services with diverse Quality-of-service (QoS) requirements. For example, a mixture of delay-sensitive applications and delay-tolerant ones must be supported. Given that the two principal wireless network resources, i.e., bandwidth and energy, are scarce, the main challenge in designing wireless networks is to use network resources as efficiently as possible while providing the QoS required by the users. This paper presents an overview of energy efficient Multi channel MAC protocols and summarizes them in a technical way.
