- Abstract
Neighbor discovery enables nodes in the networks to discover each other through simple information interaction, which was suitable for the new mobile low duty cycle sensor network (MLDC-WSN). However, because the nodes in MLDC-WSN can move randomly and sleep, the network topology was changed frequently, which results in that some nodes need a lot of energy and time to find their neighbors. How to realize fast neighbor discovery for all nodes in the network was a difficult problem in current research. To solve this problem, a new low-latency neighbor discovery algorithm based on multi-beacon messages was proposed. In this algorithm, the nodes were discovered by sending a short beacon message through their neighbor nodes, and by adjusting the time and frequency of beacon message sent, a lower neighbor discovery delay was obtained. Eventually, through quantitative analysis and simulation experiments, it is found that compared with existing algorithms, this algorithm can find all neighbor nodes in MLDC-WSN with less energy consumption, lower latency and greater probability.
