摘要：A fundamental challenge in the design of Wireless Sensor Network is to enhance the network lifetime. Wireless Sensor nodes carry limited irreplaceable power source. In single static sink node based wireless sensor network, a sensor node spends most of its energy for relaying data packets especially which are located in the surrounding area of the sink node. They dissipate their energy so fast due to many to one traffic pattern and finally they die. This uneven depletion phenomenon is known as hot spot problem which becomes more serious as the number of sensor nodes increase. Replacing these energy sources in the field is usually not practicable. So if the distance between a sensor node and sink node is reduced, the energy consumption will also reduce. Here, the proposed system implements multiple sink nodes with an energy efficient routing algorithm based on local information only. Simulation results show that the networks with this lifetime-oriented strategy achieve a significant improvement on network lifetime
