127 Seek: An Energy Efficient Control Packet Approach for WSN MAC Layer Design

Wireless sensor networks (WSN) offer a wide range of applications and it is also an intense area of research. Current research in wireless sensor networks focuses on stationary WSN where the nodes are deployed in a stationary position providing the base station with information about the subject under observation. However, a mobile sensor network is a collection of WSN nodes that are not stationary. Each of these nodes is capable of sensing, communicating and moving around. This paper proposes an energy efficient control packet and data delivery approach that can be applied in a MAC layer protocol based on S-MAC theory. The results were compared against IEEE802.15.4 (ZigBee standard) in terms of power consumption and data delivery latency using NS2.
