Wireless network adopts centralized transmission technique for transmission of power. But typical wireless ad hoc network do not have centralized coordinators for transmission of power, so it is difficult for a node in ad hoc network to predict the future transmissions of its neighbours. Thus, instead of centralized transmission, distributed MAC protocols are widely adopted in wireless ad hoc network. The authors discuss various distributed MAC protocol for power saving. Wireless network is increasing popularly, many types of wireless services have become available, including cellular systems, satellite communication networks, and Wireless Local Area Networks (WLANs).
