Abstract

To be adaptive to the traffic variations in some real-time sensor applications, AC-MAC is proposed by Jin Ai et al. Based on Sensor Medium Access Control (S-MAC), AC-MAC introduces an adaptive duty cycle scheme within the framework of S-MAC. However, frequent transceiver state switches can lead to the increasing consumption of energy. In order to solve this problem, we focus our research on how to reduce the number of transceiver state switch. By combining AC-MAC with the Dynamic Power Management, it brings in a new protocol, an Adaptive Coordinated MAC Protocol based on Dynamic Power Management for Wireless Sensor Networks, AC-MAC/DPM, which not only guarantees low delay or high throughput, but also reduces the potential energy consumption when the traffic load is high.
