An energy-efficient data gathering protocol called E2DGP that takes advantage of spatial and temporal correlation of sampling data for WSNs is proposed in this paper. E2DGP includes a clustering method of balancing energy consumption, a data prediction transmission strategy and an energy-aware multihop routing algorithm. In clustering process phase, the initial probability of node for cluster head...
Future wireless sensor networks (WSNs) are projected to run multiple applications in the same network infrastructure. While such multi-application WSNs (MA-WSNs) are economically more efficient and adapt better to the changing environments than traditional single-application WSNs, they usually require frequent code redistribution on wireless sensors, making it critical to design energy efficient post-deployment...
In this paper, a novel distributed, energy-efficient WSNs protocol for maneuvering target tracking with special consideration of spatiotemporal constraints is proposed, which is referred to as ldquomaneuvering target tracking Mobicastrdquo (MTT-Mobicast). MTT-Mobicast protocol is a spatiotemporal multicast protocol that distributes messages to the sensor nodes located in special zones that evolve...
