Performance modeling of mobile sensor networks

In the paper a performance evaluation model of mobile wireless sensor network is presented. The model is based on renewal theory. The hierarchical structure of the network holds a clusters composed of ordinary sensors. Afterwards, all clusterhead sensors belong to a backbone network which is needed for data transmission to the sink of the sensor network. Some sensors are mobile and can send their data to the clusterhead sensors. In this paper, we address one of the fundamental problems, namely performance modeling of mobile wireless sensor networks. Moreover, our model can also be used for ordinary wireless sensor networks which are static and geometrically constrained. Specific models are suggested and analysed for different communication needs.
