WSN has many advantages such as randomness, adaptively, easy use in harshclimate and so on. Because of these advantages, it can be used in many situations whichare strict in time, accuracy, reliability WSN has broad prospects, and therefore, we studythe modeling and simulation of wireless sensor. A lot of problems in theimplementation phase may be found in advance and can be modified to reduce losses. Ithas some practical significance.This paper discusses typical computing model, system modeling language anddevelopment tools. This paper researched system modeling techniques and processes ofa wireless sensor network. Analysis of the wireless sensor network architecture, andnetwork topology, routing protocols and typical mechanism was studied to determinedemand distance vector MANET routing (AODV) protocol as the wireless sensornetwork modeling protocol used.Discussed Ptolemyâ…¡simulation environment and modeling of wireless sensornetwork system constraints, system design considerations of performance indicators.The specific implementation process of every module was described in detail. Ptolemyâ…¡based tools to achieve the three modules, the node module, power module and thewhole module. Which node the node module to complete the most basic function of thesystem, such as information transmission, routing generation, maintenance, etc. Energysimulation module to complete the process of energy loss in the impact of nodeinformation received. Overall simulation model from the macro point of view the wholenetwork to receive and send messages situation.According to the design process of traditional sensor networks, this paperestablished new modeling and simulation methods. The modeling and simulationmethods which were proposed in this paper have reference value for design andapplication of wireless sensor networks in the future. |
