Power consumption is an essentially important issue and an interesting challenge to prolong the lifetime of wireless sensor network (WSN). Sensors closer to a sink node have a larger forwarding traffic burden and consume more energy than nodes further away from the sink. The whole operational lifetime of WSN is deteriorated because of such an uneven node power consumption patterns, leading to what...
In this paper, we propose a distributed event contour tracking (DECT) algorithm for multi-sink wireless sensor networks. We focus on the convex-shaped area event, which has a large effect region and may trigger many sensors at the same time. An area event may change its shape or move with time. Wild animal migration, army march, gas diffusion and chemical pollution are typical examples of area events...
The region coverage is an important affecting factor of target detection performance in wireless video sensor networks (WVSN). However, the traditional region coverage can not estimate the target detection performance properly, so the concept of effective coverage is introduced in this paper, which can be considered as the equivalent of target detection performance. Moreover, we propose an effective...
In this paper, we present a design of PRMCS (Pharos remote monitoring and control system), and study the communication protocols based on WSN (wireless sensor network) for PRMCS. The PRMCS is the integrated pharos system, consisting of RTU (remote terminal unit), control center, and sensors. Two communication patterns based on WSN are used in PRMCS, one is used on the control center, the other on...
