In last two decades, various monitoring systems have been designed and deployed in urban
environments, toward the realization of the so called smart cities. Such systems are based …

In this paper, we consider a cellular controlled unmanned aerial vehicle (UAV) network in
which multiple UAVs cooperatively complete each sensing task. We first propose a sense …

Effectively monitoring maritime environments has become a vital problem in maritime
applications. Traditional methods are not only expensive and time consuming but also …

Heterogeneous sensor networks (HSNs) comprise of different types of sensors with varying
range and sensing quality. Coverage is one of the most important performance metrics for …

Lifetime requirements and coverage demands are emphasized in wireless sensor networks.
An area coverage algorithm based on differential evolution is developed in this study to …

The coverage problem is one basic problem in the wireless sensor networks (WSN). In one
limited region, how to reasonably arrange the sensor nodes to achieve the best coverage is …

In WSN, sensors work with batteries. Sensors have only limited amount of energy in
batteries. It is infeasible to recharge or replace batteries in case of discharge. It is necessary …
