Wireless Sensor Networks(WSN) is a hot spot of the research of wireless networks currently, the key of achieving efficient transmission business is to control node energy and improve the network lifetime in wireless sensor networks. The paper first uses Boolean sensing model based on Poisson point process to identify the function of the rate of coverage and the node density in unit area, and then...
The existing data gathering scheme in wireless sensor networks usually takes place from sensors to static sinks. If sink can move randomly, data gathering process needs the cooperation of sinks. In this article, a load balancing data gathering scheme is proposed. In our scheme, the sensed data for target is stored in the storage path pointed to the network center, and the query request put forward...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
