Abstract
This paper proposes an Adaptive Energy-Saving mechanism to improve the performance of SMAC protocol (AES-SMAC). AES-SMAC is composed of two mechanisms, adaptive synchronous period (ASP) and dual element adaptive contention window (DEACW). In ASP, the cache queue of SMAC is simplified into a limited capacity of M/M/1 queuing model to calculate the node’s service efficiency. ASP also introduced a parameter called sleep conflict rate to evaluate the performance of node synchronization. Then ASP adjusts the length of synchronous period reasonably to achieve better performance. AES-SMAC protocol was compared with SMAC, ASP and DEACW via the simulation software NS2 in a scenario of Multi-hop topology. Simulation results show that AES-SMAC achieved better performance with higher throughput, lower average delay and higher energy utilization efficiency.
