Analytical modeling of multi-type failures in wireless body area networks

Wireless body area network is one of the most suitable technologies for building patient monitoring systems in hospitals, residential and work environment. The reliability of wireless body area networks is an important research issue since it may jeopardize the vital human life, unless managed properly. In this paper, a new modeling and analysis of in multi-type failures in a wireless body area networks is presented. First, the nodes are classified into types in accordance with their functions. Then, the node behavior has been modeled using a novel semi-Markov process. Simulation has finally been performed to evaluate the performance of the proposed model.
