Performance Evaluation of AREA-MAC: A Cross-Layer Perspective,
In: The Fifth International Conference on Mobile Computing and Ubiquitous Networking (ICMU 2010), April 2010.

Abstract: A medium access control (MAC) protocol generally regulates the access of devices to a shared medium. In case of wireless sensor networks (WSNs), it is also responsible to create energy-efficient links between nodes, where messages can be sent to the sink node in a timely manner. This paper evaluates AREA-MAC, a medium access control protocol designed for real-time and energy-efficient WSN applications. AREA-MAC uses the low power listening (LPL) technique with short preamble messages to minimize latency, energy consumption, and control overhead on nodes. Though AREA-MAC is mainly associated with the MAC layer, it exploits simple routing at the network layer and interacts with application as well as PHY layers. In this evaluation a crosslayer design perspective is adopted, where direct interaction between different layers is examined. Through simulation study, we evaluate the timeliness, energy-efficiency, and packet reception ratio for nodes using AREA-MAC with and without cross-layer support. Results show that the cross-layering improves network performance in terms of timeliness and energyefficiency but it comes at the cost of relatively low packet reception ratio at the sink node.
