LS-Sumlock_高密度无线传感网管理

To solve the system bottleneck when ZigBee nodes increase, a new management system for high-density heterogeneous wireless sensor network was proposed. The system employs high-speed three-level heterogeneous WSN model, which can improve both channel utilization and system throughput effectively. Our system could provide more than 20 times node capacity of original ZigBee with a single PAN, which means that theoretically it can support more than 65536×21 nodes. What is more is that our system can be very compatible with the existing small-scale WSN system, which can be easily integrated in our system to enlarge its capacity and improve its system performance.
