A comprehensive analytical model for QoS-based routing protocols evaluation in WBANs

Abstract

WBANs (Wireless Body Area Networks) emerge as a promising solution for monitoring human's physiological activities and actions and overcoming a lot of promising application scenarios. The increasing demand on real time applications in WBANs anticipates efficient quality of service (QoS) based routing protocols for data delivery. In this paper, we develop an analytical model for the framework of QoS-based routing protocols taking in charge important metrics in order to estimate the success and failure of routing process. The proposed analytical model is based on Markov chain, in which an absorbing chain is constructed to characterize the packet delivery process which take into consideration priorities of traffics, single-hop and multi-hop strategies. An extensive numerical results are presented to illustrate the effectiveness of the proposed model.
