Enhancing network lifetime in wireless sensor network is related with target coverage problem while continuously monitoring a set of targets. Target coverage problem is nothing but each target should be in the coverage range of at least one sensor node. A sensor cover is a set of sensors that covers all the targets. Target coverage is achieved by proper deployment of sensor nodes and network lifetime...
One of the major functions of a Wireless Sensor Network (WSN) is to provide the coverage to the network area. Many critical applications require different levels of coverage in the different parts of the network area which is generally called differential coverage. Providing differential coverage service in different period of time is a challenging due to the limited capabilities of the network nodes...
For some sensor network applications, the problem of sweep coverage, which periodically covers POIs (Points of Interest) to sense events, is of importance. How to schedule minimum number of mobile sensors to achieve the sweep coverage within specified sweep period is a challenging problem, especially when the POIs to be scanned exceeds certain scale and the speed of mobile sensor is limited. Therefore,...
Previously the cost and extremely limited capabilities of sensors prohibited quality of service (QoS) implementations in wireless sensor networks. With advances in technology, sensors are becoming significantly less expensive and the increases in computational and storage capabilities are opening the door for new, sophisticated algorithms to be implemented. Newer sensor network applications require...
