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 کاملNew Lower Bound on the Critical Density in Continuum Percolation
Percolation theory has become a useful tool for the analysis of large scale wireless networks. We investigate the fundamental problem of characterizing the critical density λc for Poisson random geometric graphs in continuum percolation theory. In two-dimensional space with the Euclidean norm, simulation studies show λc ≈ 1.44, while the best theoretical bounds obtained thus far are 0.696 < λc ...
متن کاملContinuum Limits for Critical Percolation and Other Stochastic Geometric Models
The talk presented at ICMP 97 focused on the scaling limits of critical percolation models, and some other systems whose salient features can be described by collections of random lines. In the scaling limit we keep track of features seen on the macroscopic scale, in situations where the short–distance scale at which the system’s basic variables are defined is taken to zero. Among the challengi...
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...
