Performance of Adaptive Scheduling MAC (AS-MAC) protocol with different AS-period in multi-hop networks

Abstract

Medium access control (MAC) protocol plays a crucial role in energy-efficiency, latency reduction and throughput for sensor networks. However, it is nontrivial to achieve good performance in different facets of metrics at the same time. In this paper, we present the performance of an Adaptive Scheduling MAC (AS-MAC) protocol with different Adaptive Scheduling period (AS-period) in multi-hop networks. AS-MAC achieves very good performance in energy-efficiency, end-to-end delay and packet delivery ratio (PDR) in different traffic loads, especially in the scenario of high traffic load. AS-MAC also exhibits adaptability to the different traffic loads with an adjustable AS-period.
