Wireless sensor networks are characterized by stringent battery resource. Owing to a wide range of applications, sensor networks are expected to support variable amounts of traffic loads. The resulting peak loads may drive the network into congestion, leading to high latency whereas low traffic loads cause energy wastage in idle-listening. This paper presents a preamble sampling based Medium Access Control (MAC) protocol for wireless sensor networks, which is highly optimized to traffic types and traffic loads in the network. Our MAC protocol exercises various optimization techniques on the preamble length based on traffic requirements. We present an analytical modeling of the protocol and derive the optimum performance parameters, which are validated using real implementation on a COTS sensor node platform. We also present in-depth simulation results for performance metrics such as power consumption, latency and delivery rates. These results adhere to our real hardware implementation results. A comparative analysis of our protocol against other state-of-the-art sensor network MAC protocols is presented in the paper to show the gains of our approach.
