Network connectivity is a critical property that provides communication foundation for most wireless sensor network (WSN) applications to operate successfully. Existing results on the WSN connectivity analysis are primarily based on a uniform distribution of sensors in a bounded field of interest. However, the sensor distribution can be non-uniform in practice due to diverse deployment strategies,...
Network connectivity, as a fundamental issue in a wireless sensor network(WSN), has been receiving considerable attention during the past decade. Most works focused on how to maintain full connectivity while conserving network resources. However, full connectivity is actually a sufficient but not necessary condition for many WSNs to communicate and function successfully. In addition, full connectivity...
Different from existing works that address the sensing coverage and connectivity for general-purpose Wireless Sensor Network (WSN) applications or treat the sensing coverage and connectivity separately, this work investigates the K-sensing detection problem of a WSN in detecting a mobile intruder by integrating the sensing coverage and connectivity. To be specific, the intruder has to be sensed by...
Wireless sensor networks (WSN) have attracted a lot attention recently. How to maintain the properties of both the full coverage and the connectivity is a hot research topic. The current research results proved that a WSN is connected when the target area is fully covered and Rc (sensor's transmission radius) is larger than twice of Rs (sensor's sensing radius). In this paper, we propose a new concept...
