A wireless sensor network consists of a large number of small, resource-constrained devices and usually operates in hostile environments that are prone to link and node failures. ...
Spatial query execution is an essential functionality of a sensor network, where a query gathers sensor data within a specific geographic region. Redundancy within a sensor networ...
Abstract. Recent researches on energy efficient coverage configuration in wireless sensor networks mainly address the goal of 100% or near 100% coverage preserving. However, we fin...
—In this paper, we propose a new control method to cover “holes” in wireless sensor networks. Many applications often face the problem of holes when some sensor nodes are dis...
