摘要
设计并实现Sumlock的异构空间高密度WSN解决方案,试图解决WSN节点空间密度趋大时所面临的通信拥塞和多功能WSNs集成的问题。采用了集中式拓扑结构,提出采用非WSN的高速通信方式来解决WSN的通信瓶颈问题,有效地改善WSN系统的信道利用率和系统吞吐率。理论上,Sumlock可以支持空间中无限多个节点,在仅采用ZigBee构建感知层时,可以支持65536×21个节点,根据一些实验的结果,实际上的支持节点可以达到200×21个左右。
A heterogeneousspace-dense WSN solution named Sumlock is designed and implemented, to solve the problem that sys-tem may meet bottleneck when the number of nodes in space increase and the troubles when multi-function WSNs are integrated. The system employs centralized topology architecture, which can solve the communication bottlenecks by employing a non-WSN way to communicate among WSNs. This architecture can improve both channel utilization and system throughput effectively. Theo-retically it can support infinite number of nodes
