“…El-Hoiydi and Decotignie proposed Wise MAC [16] that reduces the transmission duration of preamble using a table of the sleep schedules of neighbor sensor nodes to avoid overhearing. Shi et al proposed wake-up-frame (WUF) Scheme [17] that consists of the several short-wake-up-frames (SWUF) including the normal MAC layer header, the destination MAC address, and the position of the current SWUF in the whole WUF. The sensor nodes can sleep when channel is busy because it recognizes the start of a data packet and the destination address.…”

This paper presents an energy efficient medium access control (MAC) protocol for delay‐sensitive data transmission over wireless sensor network. In general, energy consumption and delay depend on channel monitoring interval (CMI) and data sensing period at each sensor node. Based on this fact, we propose a new preamble structure to effectively advertise CMI and avoid the overhearing problem. In order to pursue an effective tradeoff between energy consumption and delay, we also develop a CMI determining algorithm that searches for a sub‐optimal solution with a low computational complexity in a distributive way. Finally, experimental results are provided to compare the proposed MAC protocol with existing sensor MAC protocols. Copyright © 2010 John Wiley & Sons, Ltd.
