关于无线传感网的模拟

typical wireless sensor network (WSN) consists of a large number of sensor nodes, and is envisioned to support a wide range of applications. As most sensor nodes are operating unattended for a long lifetime, the need for robust software is very important for networked sensor systems. Simulation of networked sensor systems should be an important phase in application development. In this paper, we provide a detailed technical review of sensor network simulators. We not only list existing sensor simulators in the literature, but also summarize each simulator's advantages and disadvantages. Hence, simulator users can benefit from this summarization. We also include the most recent works, including TimeTOSSIM, AvroraZ, and COOJA, etc.
