Aimed at the problem of energy-consuming in the routings of the wireless sensor networks and taking account of,we considered the energy level of each sensor node and the total energy-consuming during data transmitting between sensor nodes,a routing model was proposed based on multi-object programming,and then the routing problem of the sensor networks was transformed into that of the multiplication of a matrix by a vector.By using the evaluation scheme based on optimization satisfactory degree,the problem of multi-object routing was simplified into a single-object optimization.Accordingly,a routing algorithm with matrix multiplication was presented to suit to the wireless sensor networks.Simulation results showed that the proposed algorithm could make the utilization of limited energy resources rational,prolong the network service life to a large extent,and decrease the average energy consumption.
