Group management service plays a key role in wireless sensor networks (WSNs) as it provides support to high level middleware services such as object tracking, security, fault-tole...
Interference ranges can dramatically affect the throughput in wireless sensor networks. While the transmission range defines the maximum physical range of a radio signal the inter...
Abstract— Coverage is a fundamental problem in sensor networks. In this paper, we addressed the coverage problem from two different view points and refer to them as the worst and...
Abstract. The coverage problem in wireless sensor networks (WSNs) is to determine the number of active sensor nodes needed to cover the sensing area. The purpose is to extend the l...
