Sensing and coverage are the two relevant tasks for a sensor network. Quality of sensor network totally depends upon the sensing ability of sensors. In a certain monitored region success of detecting or sensing an object with the help of sensor network tells that how efficiently the network coverage perform. Here in this paper we have proposed a clustering algorithm for the deployment of sensor...

Seamless connectivity in 4G wireless networks requires the development of intelligent proactive mechanisms for efficiently predicting vertical handovers. Random device mobility patterns further increase the complexity of the handover process. Geographical topologies such as indoor and outdoor environments also exert additional constraints on network coverage and device mobility. The ability of ...

At present, free-to-move node self-deployment algorithms aim at event coverage and cannot improve network coverage under the premise of considering network connectivity, network reliability and network deployment energy consumption. Thus, this study proposes pigeon-based self-deployment algorithm (PSA) for underwater wireless sensor networks to overcome the limitations of these existing algorit...

Multi-hop relay network systems allow users to communicate with a base station via a relay station, such as WiMAX 802.16j and Long Term Evolution (LTE)-Advanced. The overall coverage for the systems can be increased apparently and the throughput for the users will be enhanced by deploying suitable relay stations in such network systems. Considering a trade-off among the network throughput, the ...

In order to reduce the algorithm complexity of the target coverage problem in Wireless Sensor Network, three kinds of approaches are designed to decrease the network scale, that is, one is deleting the redundant sensor nodes, another is removing the redundant targets, and the third is decomposing the target coverage graph into multiple independent sub graphs. This paper proves that the three ap...
