Wireless sensor networks are characterised by dense deployment of energy constrained
nodes. Owing to the deployment of large number of sensor nodes in uncontrolled hostile …

With an increasing acceptance of Wireless Sensor Networks (WSNs), the health of individual
sensor is becoming critical in identifying important events in the region of interest. One of the …

Wireless sensor networks (WSN) are inherently fault-prone due to the shared wireless
communication medium and harsh environments in which they are deployed. Energy is one …

Energy is one of the most constraining factors in wireless sensor networks and node failures
due to crash and energy exhaustion are commonplace. In order to avoid degradation of …

空间信息网是一种融合陆海空天信息系统的新型自组织网络, 成为研究热点.
针对网络特点和应用需求, 提出一种预防和恢复相结合的拓扑重构策略, 通过检测拓扑关键点 …

Wireless Sensor networks (WSN) are inherently fault-prone due to the shared wireless
communication medium and harsh environments in which they are deployed. Energy is one …

In this paper, we consider the sensor replacement problem in hybrid wireless sensor
networks composed of mobile and static sensors. Mobility equipped mobile sensors are …

This paper identifies faulty sensor (s) in a polynomial-based data aggregation scenario,
TREG proposed in our earlier work. In TREG, function approximation is performed over the …

In the past few years wireless sensor networks have received a greater interest in
application such as disaster management, border protection, combat field reconnaissance …
