基于联合退避-功率感知机制的物联网节点信息防碰撞算法
Node Information Anti-collision Algorithm for Internet of Things Based on Combining Backoff Power Perception Mechanism
摘要
Abstract
In order to overcome the problem of serious signal interference induced by Internet of Things(IoT) node data confliction in current IoT node anti-collision algorithm,a new IoT node information anti-collision algorithm is proposed.The discrete orthogonal modulation and demodulation mechanisms of the radio frequency identification signal are constructed to reduce the channel collision caused by the mutual interference among the nodes.Combining backoff power perception mechanism is built and node data collision avoidance rules are defined to improve the fluctuation range of the transmitted power.Experimental results show that this algorithm has a longer signal recognition distance and lower channel collision probability compared with ColorWava and Decision Information Controlling Algorithm(DICA).关键词
