Data Relay Node Aware Optimization Algorithm of Mobile Sensor Networks Based on Time Migration Mechanism

In order to solve the data transmission process of mobile sensor network data transmission, the ability to transmit data is weak, and it is difficult to reduce the level of data link, which is easy to cause the problem of network congestion. In this paper, a data relay node aware optimization algorithm for mobile sensor networks based on time migration mechanism is proposed. First of all, through the sensor nodes in the collision process of quasi time migration factors, take based on series parallel calculation of the optimal data transmission success rate, to achieve the initial screening of network transmission link; and then according to the node data delivery success rate, through the analysis of the data receiving node-sending process, data delivery threshold, reduce the delay of data the forwarding process; then based on the adaptive node perception, there are multiple paths to transmit data in the node, the perception of the optimal transmission path and a suboptimal transmission path as the optimal transmission path to the backup cache, optimize the transmission congestion control node, reduce the effect of jitter on data link transmission. Simulation results show that compared with the CS algorithm in WSN, PR Cara algorithm, algorithm in this paper has higher next hop node transmission success delivery probability and data packet transmission level, and lower the degree of link congestion, effectively reducing the data transmission delay.
