Critical Density for Coverage and Connectivity in Two-Dimensional Aligned-Orientation Directional Sensor Networks Using Continuum Percolation
Sensing coverage is one of the fundamental design issues in wireless sensor networks, which reflects the surveillance quality provided by them. Moreover, network connectivity enables the gathered data by sensors to reach to the sink node. Given an initially uncovered field, and as more and more directional sensors are continuously added to the sensor network, the size of partial covered areas i...
متن کاملCritical density for coverage and connectivity in two-dimensional fixed-orientation directional sensor networks using continuum percolation
Given an initially uncovered field, and as more and more directional sensors (sensors with sector shape sensing area) are continuously added to the sensor network, the size of partial covered areas increases. At some point, the situation abruptly changes from small fragmented covered areas to a single large covered area. This abrupt change is called the sensing-coverage phase transition (SCPT)....
متن کاملDirectional Wireless Sensor Networks with Guaranteed and Coverage and Connectivity
To successfully perform the assigned sensing tasks by a wireless sensor network, sensors must both form a connected network via multi-hop wireless communication, and cover the entire working area or some specific locations. Therefore, deploying a wireless sensor network to provide connected coverage becomes a critical research issue. Most of the existing work [1] on the connected coverage probl...
متن کاملImproving Target Coverage and Network Connectivity of Mobile Sensor Networks
Mobile sensor network is the collection of independent and scattered sensors with capacity of mobility. In recent years, Mobility of Sensors has been utilized to improve the target coverage quality and network connectivity in randomly deployed mobile sensor networks. Target coverage and Network connectivity are two main challenging issues of mobile sensor networks. Target coverage covers a set ...
متن کاملCoverage and Connectivity Problem in Sensor Networks
In over deployed sensor networks, one approach to Conserve energy is to keep only a small subset of sensors active at Any instant. For the coverage problems, the monitoring area in a set of points that require sensing, called demand points, and consider that the node coverage area is a circle of range R, where R is the sensing range, If the Distance between a demand point and a sensor node is l...
