Data communication in wireless sensor networks (WSNs) exhibits distinctive characteristics. Routing in WSNs still relies on simple variations of traditional distance vector or link state based protocols, thus suffering low throughput and less robustness. Drawing intuitions from the Brownian motions where localized momentum exchanges enable global energy diffusion, we propose an innovative routing...
Sensor data streams exhibit unique characteristics such as inherent information uncertainty, intrinsic data sample correlations (both within and across streams) and resource constraints. In this paper, we introduce a new data model, called probabilistic stream relational algebra (PSRA), that extends conventional relational model to capture these new characteristics faced in managing data in sensor...
