Nodes Deployment Method across Specific Zone of NB-IoT Based Heterogeneous Wireless Sensor Networks

NB-IoT leads to innovation in wireless sensor network. In NB-IoT-based Wireless Sensor Network, it is still a challenge to alter topology in accordance with actual applications. Since application-oriented topology control needs to change along with application requirements, so as to adapt to different scenes. We propose a node deployment method across specific zone with intelligent algorithm. The method predicts possible consumption of traffic and energy and designs the deploy model, which is optimized then using particle swarm optimization. Compared with methods with fixed threshold, the classification with adaptive threshold to determine node deployment improves deploy effect and enlarges monitoring scope.
