Contention-Free Station Communication Matching Algorithm in Multi-Hop Power Management for Wireless Ad-Hoc Networks

摘要

Many single-hop power management mechanisms have been proposed in previous studies. Compared to the multi-hop power management mechanisms, the design of the single-hop power management mechanism in a wireless network is relatively simple. However, existing methods are difficult to balance the transmission utilization and energy efficiency. This paper proposes the Contention-Free Station Communication Matching (CFSCM) algorithm for multi-hop power management. CFSCM is based on list-based scheduling with Time-Division Multiple Access (TDMA). CFSCMappropriately schedules the data transmission of nodes andpower management. In addition, CFSCM adopts multiple channels to improve the performance of data transmission. Simulation results show that the proposed method can significantly improve transmission utilization and avoid the hidden terminal problems.
