1 Hop or 2 hops: Topology analysis in Body Area Network

Research output: Contribution to conferenceOther


Wireless Body Area Networks (WBANs) have recently received much attention due to the possibility to be usedin healthcare applications. For these applications, link reliabilityand energy efficiency are critical issues, as in many cases, informationcarried can be vital for the patient and batteries cannot be easily replaced. The wireless on-body channel experiences significant temporal variation due to body movements and the use of relays is sometimes necessary in order to guarantee reliability or improve lifetime.In this paper, an experimental evaluation is used to givea better understanding about reliability, energy consumptionand lifetime in a single hop or a two hops communication.This analysis keeps into consideration the correlations between propagation on different links which affect simultaneously the time-varying connectivity on different links of the body. Theresults shows that an off-body relays could be used to increase data reliability, minimize energy requirements and maximize network lifetime.
