Abstract :
In this work, we consider modeling of a wireless sensor network with a TDMA media access protocol with slot reuse. It is assumed that the nodes have two modes of operation, active and sleep modes. We model the sensor network as a Jackson network with node breakdowns. We determine the joint distribution of the queue lengths in the sensor network. From this result, we derive the probability distribution of the number of active nodes and blocking probability of node activation. Then, we present the mean packet delay, average down period of a node as well as the network throughput. Finally, we discuss how the derived results may be used in the design of sensor networks
