Wireless Body Area Networks (WBANs) comprise a fast growing technology that enables remote monitoring of vital signs and is aimed at providing support for healthcare services. These systems normally use low-power wireless technologies, such as IEEE 802.15.4, which are limited in bandwidth and range. The dense population of patients in places like hospitals is likely to raise situations where the coexistence of multiple WBANs results in severe loss of performance and functionality. Therefore providing coexistence mitigation mechanisms for this kind of systems is a necessity. In this paper, we present the performance analysis of a simulated mechanism designed to mitigate the harmful effects of coexistence on the operation of IEEE 802.15.4 based WBANs. The distributed and collaborative design of this scheme makes it well suited for typical healthcare applications. The proposed mechanism detects the coexistence situation and reorganizes the communication of the coexisting WBANs. We implement the proposed scheme and show the simulation results using OPNET.
