On the Shortest Recycle Path Algorithm of Wireless Sensor Node

Along with the spreading application of wireless sensor network, once the node energy is exhausted, it will cause environmental pollution. Therefore, the problem of node recovery becomes increasingly important. The automatic recycling of robot will become one of the feasible methods. The key is how to use less time and energy consumption to recycle all nodes as well as prolong the lifespan of wireless sensor network. This paper proposes a recovery algorithm based on the greed algorithm. Through quantitative tests, the results show that the proposed new algorithm can save the energy consumption and maintain the lifespan of wireless network, thus reaching a balance.
