A Target Coverage Scheduling Scheme Based on Genetic Algorithms in Directional Sensor Networks
As a promising tool for monitoring the physical world, directional sensor networks (DSNs) consisting of a large number of directional sensors are attracting increasing attention. As directional sensors in DSNs have limited battery power and restricted angles of sensing range, maximizing the network lifetime while monitoring all the targets in a given area remains a challenge. A major technique ...
متن کاملImproving Energy-Efficient Target Coverage in Visual Sensor Networks
Target coverage is one of the important problems in visual sensor networks. The coverage should be accompanied with an efficient use of energy in order to increase the network lifetime. In this paper, we address the maximum lifetime for visual sensor networks (MLV) problem by maximizing the network lifetime while covering all the targets. For this purpose, we develop a simulated annealing (SA) ...
متن کاملProbabilistic coverage based sensor scheduling for target tracking sensor networks
In target tracking sensor networks, tracking quality and network lifetime are two conflicting optimization goals due to the limited battery power of the sensor nodes. During the movement of a target, how to select an optimal subset of sensors to wake up is of critical importance both for extending network lifetime and guaranteeing tracking quality. In this paper, we first propose a probabilisti...
متن کاملTarget coverage through distributed clustering in directional sensor networks
Maximum target coverage with minimum number of sensor nodes, known as an MCMS problem, is an important problem in directional sensor networks (DSNs). For guaranteed coverage and event reporting, the underlying mechanism must ensure that all targets are covered by the sensors and the resulting network is connected. Existing solutions allow individual sensor nodes to determine the sensing directi...

The wireless sensor networks have emerged as a promising tool for monitoring the physical world. Recently directional sensor networks (DSNs) consisting of directional sensors have gained attention. DSNs comprise a large number of sensors equipped with limited angles of sensing range and a limited battery. In DSNs, maximizing network lifetime while covering all the targets in a given area is sti...
