Wireless Body Area Networks (WBAN), standardized as IEEE 802.15.6, enable digital devices on/around thehuman body to communicate with one another. WBAN is essentially a person’s piconet consisting of a master (mobile)device and several slave devices, which follows his/her mobility pattern, and hence, occasionally collides with anotherpiconet as people meet or pass by. As such, a mechanism to detect collision and avoid interference is needed forintra-piconet communications. In this paper, we focus on this notorious problem of piconet collision and proposeDistributed Time Division Piconet Coexistence (DTDPC) using local time offset exchange as a simple, attractivesolution. The proposed DTDPC provides different level of services for various applications. Besides our simulationresults have shown that the proposed solution outperforms the conventional CSMA protocols.
