Wireless Sensor Networks (WSNs) are composed of a large number of sensor nodes that are densely deployed either inside the phenomenon or very close to it. Energy efficiency and network lifetime are two challenges that most of researchers deal with. In general, Base Station (BS) used to retrieve data from sensor nodes is far from the sensor field and how to adjust the communication between nodes and BS to achieve energy efficiency and long network lifetime is very important. In this paper, the authors propose a novel sub-optimum Average Lifetime-oriented Long-distance (ALL) data transmission algorithm. It makes tradeoff between energy cost and residual energy and balances lifetime among all sensor nodes to achieve dramatic lifetime prolongation for network.
