LS-Sumlock:高密度异构无线传感网管理

LS-Sumlock: Management System for High-Density Heterogeneous Wireless Sensor Network

为解决ZigBee在节点趋多时面临的系统瓶颈,提出了一种新的构建大规模异构无线传感器网络的系统架构。该系统架构采用了高速三层异构WSN模型,有效地改善WSN系统的信道利用率和系统吞吐率。LS-Sumlock提供比传统的ZigBee单PAN多约20倍的系统容量,理论上,支持超过65536×21个节点。从3个层面改善了整个系统的通信和处理能力,并且能够很好地兼容现有的小规模WSN系统,能够通过简单的方法为现有的WSN扩容并改善其系统性能。

To solve the system bottleneck when ZigBee nodes increase, a new management system for high-density heterogeneous wireless sensor networkwas proposed. The system employs high-speed three-level heterogeneous WSN model, which can improve both channel utilization and system throughput effectively. The system could provides 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 system can be very compatible with the existing small-scale WSN system, which can be easily integrated in system to enlarge its capacity and improve its system performance.
