The improvement of sensor networks' lifetime has been a major research challenge in recent years. This is because sensor nodes are battery powered and may be difficult to replace when deployed. Low energy adaptive clustering hierarchical (LEACH) routing ...
In this paper, a protocol called distributed genetic algorithm for lifetime coverage optimisation (DiGALCO) is suggested to preserve the coverage and enhance the lifetime of a wireless sensor network (WSN). DiGALCO combines three energy-efficient schemes: ...
In target based wireless sensor networks (WSNs), coverage and connectivity are the two most important issues for guaranteed data forwarding from each target to a remote base station (BS). Given a set of target points, finding minimum number of potential ...
