摘　　要：针对现有无线传感网络模拟器的难以扩展、单应用和低效率等问题,提出了一种新型的LENS模拟器。在设计上LENS利用了部件编程模型,具备良好的可扩展性。通过使用脚本,可为网络中的节点设置多个应用程序,并对网络拓扑进行详细控制。同时,nesC语言被用于协议栈的编写,有利于所模拟的算法向实际硬件平台的移植,并且具有较高的执行效率。仿真试验表明在模拟大规模无线传感网络时,LENS的内存损耗仅是J-Sim的5%,而运行时间比J-Sim快5-7倍。关键词:无线传感网络;模拟器;可配置;多应用;In view of the fact that existing wireless sensor network simulators have problems of extensibility, single - application, and low efficiency, a new simulator, called LENS, is proposed. LENS uses component - programming model, and possesses good extensibility. By using script, the new simulator can assign multi - applications to nodes in the network, and control in detail the topology of the network. Meanwhile, nesC programming language is used to implement the protocol stack. This facilitates the port of the simulated algorithms towards the physical platform, also have relatively high execution speed. Simulation results showed that when simulating large - scale wireless sensor networks the memory consumption of LENS is only 5 per cent of that of J - Sim, and the execution speed is 5 - 7 times faster than that of J - Sim.
