RETRACTED ARTICLE: Research on distributed localization algorithm for wireless sensor network nodes in multimedia data transmission process

Abstract

Aiming at the need of massive transmission bandwidth and efficient transmission efficiency in the transmission of multimedia data in wireless sensor networks, this paper proposes an improved BP neural network localization algorithm based on artificial bee colony algorithm to solve the problem of network node localization in the transmission of multimedia data in wireless sensor networks. The algorithm first completes the coarse location of the nodes by the three side distributed location algorithm through signal strength. Then, the BP neural network is optimized by artificial bee colony to locate accurately. The distance weight is determined based on the precise location and the errors generated in the process of ranging are corrected. Finally, a localization algorithm with high accuracy and robustness for wireless sensor network nodes is formed. The simulation results show that the proposed algorithm has a significant improvement in the performance and efficiency of sensor node positioning, and has a broad prospect in the transmission of multimedia data.
