Abstract: Wireless Sensor Networks are found suitable for applications such as surveillance, precision agriculture, smart homes, automation, vehicular traffic management, habitat monitoring, and disaster detection. A medium Access Control (MAC) protocol is the first protocol layer above the Physical Layer (PHY) and consequently MAC protocols are heavily influenced by its properties. The fundamental task of any MAC protocol is to regulate the access of a number of nodes to a shared medium in such a way that certain application-dependent performance requirements are satisfied. Medium access in wireless networks is difficult mainly because of impossible (or very difficult) to send and receive at the same time. Interference situation at receiver is what counts for transmission success, but can be very different from what sender can observe. High error rates (for signaling packets) compound the issues. In this paper, we present an energy efficient MAC protocol for WSNs that avoids overhearing and reduces contention and delay by asynchronously scheduling the wakeup time of neighboring nodes.
Keywords: MAC, PHY, contention.
