Due to the hardware characteristic of sensor nodes, energy consumption and balance are major problems in routing algorithm in Wireless Sensor Networks (WSNs). The networks should choose a route which not only has fewer hop count, but also makes the round of the nodes with less residual energy. In this paper, the authors first investigate the energy characteristic of the route and propose a routing-cost model. Then they compare the performance of routing-cost constructing method with other constructing methods on the platform of the ant routing algorithm in WSNs.
