Poster: behavior-aware probabilistic routing for wireless body area sensor networks

Wireless Body Area Networks (WBANs) can provide continuous and remote monitoring of patients´ physiological history, facilitate automatic sports training, and promote interactive games. However, existing single-hop wireless communication scheme faces two major challenges: the impermeability of human body to radio waves at frequencies commonly used in WBANs, and the highly dynamic network topology resulted from human movements. In this paper, (i) a prototype of multi-hop WBAN is built to characterize the network connectivity during human movements, (ii) a probabilistic routing algorithm is proposed, and (iii) the evaluation on our prototype system shows that the proposed scheme outperforms existing routings in terms of average delivery ratio, number of hops, and end-to-end delay.
