Enhancement of Asynchronous MAC Protocol in Wireless Sensor Networks for Smart Monitoring Applications
Up to now, many research works have been focusing on designs in MAC layer of Wireless Sensor Networks (WSNs) to target high throughput, low latency and solving the problem of idle listening. In this paper, an enhancement of Low-power asynchronous protocol for MAC layer, namely E-MAC, is proposed to target a long lifetime of sensor nodes working 6LoWPAN/IPv6 networks. Moreover, the E-MAC protocol is implemented on TI low-power platforms to verify the efficiency of the proposed design. Several parameters such as energy consumption, latency and packet delivery ratio are simulated and measured in a real monitoring test-bed to show the better performance in comparison with other popular MAC protocols.
