摘要：In wireless sensor network, due to impossibility of replacing battery, the problem of energy and network lifetime is one of the important parameters. In asymmetric sensor networks, due to limited range of normal sensors it is not possible to communicate directly with central station by these sensors. In noted network, manager nodes are used which have more energy, processing power and broader telecommunication range. Connectivity and sending information to central station are done through them. The optimal selection and considering the energy of intermediate nodes to select and transmit data and also increasing network lifetime is one of the most important parts of wireless network design. In this paper, a gravitational force algorithm is used to solve the problem that is a power aware Selection algorithm in sensor network.
