Target Q-Coverage Problem with Bounded Service Delay in Directional Sensor Networks

Improving 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) ...

Target 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...

Connected Coverage in Wireless Sensor Networks with Directional Antennas

In this paper we address a new unexplored problem concerning directional antennas in wireless sensor networks (WSNs), namely the optimal patterns that achieve connected coverage. As their name implies, directional antennas can focus their transmission energy in a certain direction. This feature gives rise to lower cross-interference and greater communication distance, given certain amount of en...
