Aimed at the inapplicability of LEACH protocol for large-scale sensor network and uneven energy consumption, a Distributed Self-organizing Clustering Routing protocol (DSCR) for large-scale sensor network is proposed. Based on clustering, the network routing is divided into two levels: parent cluster and cluster. The cluster structure is formed by the back-off mechanism related to the residual energy...
This paper analyzes the coverage problem under the shadow fading of the WSN with sensors deployed in the monitor region randomly and high density. Because the target sensed probability by multi-sensors is better than the single sensor, in the paper the collaborative sensing model is deduced, and then a coverage configuration scheme based on cooperative sensing model under shadowing is promoted. In...
Coverage control in high dense wireless sensor network is an important way to make the network more efficient, which can schedule the sensors in active or sleeping state at the right time on the precondition of maintaining the network coverage. Aiming to make the best of redundant coverage of the high dense network, an area control protocol based on probabilistic coverage model is designed. To simplify...
