  3. Abstract:
  4. This paper proposes a new medium-access control (MAC) protocol designed for wireless sensor networks. A wireless sensor network is an array of large number of sensors interconnected by a multi-hop ad-hoc network. The primary objective for the sensor network is achieving to low-power consumption while latency is usually less important compare to traditional wireless networks. This characteristic of sensor network motivates the design of new MAC layer so that power consumption is reduced. In this paper, a novel traffic-aware algorithm based on distributed node schedule management (DMD) protocol is introduced that utilizes distributed dynamic node scheduling strategy to dramatically increase energy saving, especially in intermediate devices inside a multi-hop network. The simulation results show noticeable power consumption improvements compared to 802.1 I-like, sensor MAC and dynamic SMAC protocols especially in the large scales which has been achieved in trade of more latency. © 2004 IEEE
