Critical 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)....

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...

Directional 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...

Two-Dimensional Critical Percolation

We use SLE6 paths to construct a process of continuum nonsimple loops in the plane and prove that this process coincides with the full continuum scaling limit of 2D critical site percolation on the triangular lattice – that is, the scaling limit of the set of all interfaces between different clusters. Some properties of the loop process, including conformal invariance, are also proved. In the m...

Coverage 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...
