Energy efficient, delay sensitive, fault tolerant wireless sensor network for military monitoring

In this paper, a new TDMA based wireless sensor network (WSN) for military monitoring is proposed. The most important design considerations of the newly developed sensor network system are energy consumption, delay, scalability and fault tolerance. There are three main parts of the system: time synchronization based on the sink with high range transmitter, SyncHRT; data indicator slot mechanism, DISM; and a new time scheduling mechanism ft_DTSM. Analytic model has shown that energy consumption performance of the newly proposed system is better than most of the existing MAC layers for WSN. According to simulation studies, its delay performance is also superior to most of the other WSN systems. Although there may be other architectures which perform better than our system for certain performance metrics, the newly proposed military monitoring system can operate with a good optimization on energy consumption, delay and fault tolerance.
