摘要：the wireless sensor networks (WSN) are widely used for the scientific, industrial and social applications such as earth science, machines data logging, air pollution measurements etc. In most of the applications the network nodes has to be relay on their battery sources because of their placements or any other reasons. Since the battery can provide only limited power the node there is always a possibility of complete power drainage of nodes which can deeply affect the overall communication of the network. Since the node nearest to sink has to deal with maximum traffic which drain it quickly, hence to minimize the power relay node are used which are supplied by some high capacity power source and used to communicate with sink nodes. However the placement of relay nodes and sink nodes are also crucial because every node need to communicate with it and larger distance may cause greater power requirements for transmission. This paper presents a genetic algorithm based optimal sink and relay node placement technique to minimize the energy usage while managing and considering as possible as practical conditions like nodes distribution, nodes data transmission rates, transmission range of the nodes, processing power requirements of nodes
