DTN routing in body sensor networks with dynamic postural partitioning

摘要: This paper presents novel store-and-forward packet routing algorithms for Wireless Body Area Networks (WBAN) with frequent postural partitioning. A prototype WBAN has been constructed experimentally characterizing on-body topology disconnections in the presence of ultra short range radio links, unpredictable RF attenuation, and human mobility. On-body DTN protocols are then developed using a stochastic link cost formulation, capturing multi-scale topological localities movements. Performance proposed evaluated via simulation, compared number existing single-copy an flooding mechanism that serves as performance benchmark delay lower-bound. It is shown modeling spatio-temporal locality disconnection patterns, can provide better to probabilistic, opportunistic, utility-based literature.
