Abstract

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.
