Abstract: Opportunistic routing has been an efficient approach for improving the performance of wireless multihop networks due to its salient features to take advantage of the broadcast and lossy nature of wireless channels. In this paper, we propose a deep reinforcement learning based energy efficient opportunistic routing algorithm for wireless multihop networks, which enables a learning agent to train and learn optimized routing policy to reduce the transmission time while balancing the energy consumption to extend the life of the network in an opportunistic way. Furthermore, the proposed algorithm can significantly alleviate the cold start problem and achieve better initial performance. Simulation results demonstrate that the proposed algorithm yield better performance as compared with existing algorithms.
