Abstract
In this study, RFID technology and wireless photoelectric sensor (WOSN) technology were combined in the acquisition of traffic information. RFID tag and photoelectric sensor were used as a node to build a traffic information collection network. To improve the life cycle and load performance of the network, and achieve the optimal distribution among nodes, the ant colony optimization (ACO) algorithm was taken as the research object, and the network node distribution routing algorithm of multiple RFID tags-photoelectric sensor nodes was designed. The improved ACO based on energy and distance was selected for self-organizing distribution, so that the nodes distributed locally could be regarded as a whole. Then, each local head node transmitted information based on the route generated by the improved ACO, so that the traffic information obtained by each head node was sent to the aggregation node at the lowest cost. In the experiment, the multi RFID tag-photoelectric sensor node distribution based on the improved ACO can extend the network life cycle, and achieve a balanced network load.
