- Abstract
A novel wireless ad hoc network architecture based on cellular infrastructure is proposed for electric internet of things to address the problem in traditional wireless Ad hoc networks. The proposed scheme combines D2D with Ad Hoc network, benefiting from the advantage of centralized resource scheduling and cooperation mechanism, the deployment time and robustness of the network can be greatly improved. At the same time, considering the strong correlation of shadow fading of cellular links in a D2D cluster, the probability of decoding failure for all receiving nodes could dramatically increases in a specific scenario. To address the problem, a fast retransmission and error correction scheme is designed. The proposed scheme exploits the soft information combine technique. Therefore, the base station does not need to retransmit the error packages. Consequently, the capacity of self-healing and robustness of electric internet of things is enhanced. Simulation results show that the proposed cellular D2 D ad hoc network and retransmission scheme can achieve better performance in terms of both average number of retransmission and network delay.
