Low energy consumption is very important in WSN (Wireless Sensor Network), since sensor nodes are powered by limited power batteries. In recent years, mobile relay has been studied in order to save the energy consumption on WSN. Initial route construction is needed for mobile relay to determine the sequence of relaying nodes. Battery-Aware Initial Route construction by Dijkstra's Algorithm (BAIR-D) has been proposed. BAIR-D employs Dijkstra's algorithm and takes into account node's battery level into the cost function to find the initial route. However, when applying it to multiple sources, the constructed paths are necessarily overlapped with high probability.
