Modeling performance of CSMA/CA with retransmissions in wireless personal area networks

Despite the widespread uses in military, smart building, habitat monitoring, Wireless sensor networks (WSNs) just begun showing their superiority in the medical and healthcare domain. Facing same challenges as other applications, deployment of WPANs in medical domain exert many more stringent requirements, due to the nature of high accessibility and the privacy sensitive requirement of medical environment, the application of WPANs must be carefully examined before practical use. This paper considers the performance of WPANs deployed in the specific domains, particularly on the behavior of sensor nodes while accessing the shared channels during communicating each other, by theory of Markov chain. © 2013, Atlantis Press.
