Random backoff algorithm for multi link transmission in embedded wireless sensor networks
To ensure smooth link transmission and stable network operation,a random backoff algorithm for multi link transmission in embedded wireless sensor networks was proposed.According to actual needs,use different frequency channels or orthogonal channels to transfer data,the cluster head rate vector was adjusted according to the principles and attributes of utility function design,and the backoff window size consistent was made.By recording the backoff times of embedded wireless sensor network link transmission,clarifying the busy status of the network,increasing the transmission success rate gain,reducing link transmission competition,and achieving network security and stability through adaptive random backoff correction,the dynamic adjustment of the initial competition window was carried out.The results show that the proposed algorithm has a high system throughput,can reduce network congestion and occurrence of link data collisions.
