Abstract: In order to satisfy the requirement of data freshness in Wireless Sensor Network(WSN), by combining network data transportation and mobile element transportation, this paper proposes an efficient carrying routing algorithm. It calculates the optimal node positions for mobile elements to transmit data, and plans the paths of mobile elements, so that the energy consumption of sensor nodes is reduced and the network performance is improved. Simulation results show that the proposed algorithm can reduce network energy consumption under the premise of guaranteeing data freshness.
