  • Abstract This paper considers a hybrid wireless sensor network. That contains two kinds of sensors, static and mobile sensors. Static sensors are scattered in the sensing field for environmental monitoring and indicating where events occurring. Then, mobile sensors can be dispatched to visit these event sites to conduct more advanced analysis. A big challenge is how to dispatch these mobile sensors to visit event sites using less energy, and extend the system lifetime accordingly. To prolong the usage time of mobile sensors, we also consider deploying few wireless chargers in the network to adaptively charge mobile sensors. Based on the above network architecture, this thesis proposes an efficient sensor dispatch mechanism to balance energy consumption of mobile sensors, and thereby extend their lifetime. Moreover, this mechanism can also select the best wireless charger for mobile sensors to charge in accordance with mobile sensors’ traveling path. In this way, mobile sensors can not only charge more power, but also reduce the amount of energy spent to more to a wireless charger. Through simulations, we demonstrate that our sensor dispatch mechanism can significantly increase the system lifetime.
