Abstract

In this paper a high throughput, low latency, mobility adaptive and energy efficient medium access protocol MAC called Mobility Adaptive MA for wireless sensor networks. MA-MAC ensures that transmissions incur no collisions, and allows nodes to undergo sleep mode whenever they are not transmitting or receiving. It uses delay allocation scheme based on traffic priority at each node and avoids allocating same backoff delay for more than one node unless they are in separate clusters. It also allows nodes to determine when they can switch to sleep mode during operation. MA-MAC for mobile nodes provides fast association between the mobile node and the cluster coordinator. The proposed MAC performs well in both static and mobile scenarios, which shows its significance over existing MAC protocols proposed for mobile applications. The performance of MA-MAC is evaluated through extensive simulation, analysis and comparison with other mobility aware MAC protocols. The results show that MA-MAC outperforms significantly the existing CSMA/CA, Sensor Mac S-MAC, Mobile MAC MOB-MAC, Mobility aware Delay sensitive MAC MD-MAC and Dynamic Sensor MAC DS-MAC protocols including throughput, latency and energy consumption.
