This paper provides a comprehensive survey on addressing the target coverage problem to maximize the network lifetime by placing the minimum number of sensors and without affecting the quality of monitoring. Energy utilization is one of the important key challenges in the research area of sensor networks. Deployment of sensor nodes should be with extreme coverage and connectivity but with less ...

In the context of coverage planning and control, the power of the common pilot channel signal determines the coverage area of a network cell. It also impacts the network capacity and thus the quality of service. We consider the problem of minimizing the total amount of pilot power subject to a full coverage constraint. Our optimization approach, based on parallel autonomous agents, gives very g...

Barrier coverage of a wireless sensor network is a critical issue in military and homeland security applications, aiming to detect intruders that attempt to cross the deployed region. While a range of problems related to barrier coverage have been investigated, little effort has been made to explore the effects of different sensor deployment strategies and mechanisms to improve barrier coverage...

Abstract The problem of an optimal coverage a wireless sensor network area is considered. To solve this problem, Cellular Automata (CA) approach proposed. More specifically, the objective to find CA rules which are able cover 2D space by minimum number so–called “Sensor Tiles”. A tile consists von Neumann neighborhood range 2 centered at “point” and surrounded 12 sensing “pixels”. Two probabili...

The research on wireless sensor networks has achieved a lot in recent years and some of the results have been put into practical applications, but with increasing demand requirements for networks, many old new problems need to be solved urgently. In this paper, data topology optimization algorithm based local tree reconstruction heterogeneous is proposed transmission that are easily affected by...
