A Cross-Layer Optimization Scheme for Energy-Saving MAC Protocol Based on Wireless Ad-Hoc Network

In order to save energy and prolong the network lifetime for wireless ad-hoc network, this paper focuses on a cross-layer optimization design for energy-saving MAC protocol. As a consequence, Traffic Adaptive Energy-saving MAC protocol (TAE-MAC), as a new MAC protocol, is proposed. To the end for energy conservation, This protocol using multi-technique methods, such as multiple users low power detection (MUD-LPD), orthogonal frequency division multiplexing and code division multiple access (OFDM-CDMA), reduces the possibility of collision, bit error rate(BER), packet loss, excessive idle listening to channel and improves the success probability of data transmission. Eventually the simulation results show that the propose TAE-MAC outperforms CSMA/CA or TDMA in saving energy and energy efficiency for wireless ad-hoc network.
