【摘要】 提出一种基于节点聚类的无线传感器网络模拟方法,部署同类应用的节点在模拟器中采用单一实体建模,通过多个实体之间的通信实现不同节点的交互,并利用实体之间的同步驱动模拟事件的顺序进行。基于节点聚类方法,在主流模拟工具TOSSIM的基础上设计并实现了一个无线传感器网络模拟器ETMA;实验结果表明,基于节点聚类的模拟方法不仅可支持多应用无线传感器网络的模拟,同时还具有良好的可伸缩性。更多还原

【Abstract】 A node clustering based approach was proposed to solve effectively the large scale WSN simulation with mul- tiple applications by partitioning nodes into different clusters. Nodes in a single cluster running the same application were simulated with the same single entity. Interactions between nodes were simulated by entity communication, and a syn- chronous mechanism was also proposed to ensure the simulation events execute orderly. A node clustering based simula- tor ETMA was designed and implemented on top of TOSSIM. Empirical studies on ETMA show that the node clustering approach can support multi-application WSN simulation with high scalability.更多还原
