Embodiment Construction

[0065] In order to improve the simulation efficiency of the simulator, the embodiment of the present invention is based on the idea of ​​a discrete event simulation model. The so-called discrete event-driven model system refers to a class of systems whose activities and state changes only occur at discrete time points. The state of this type of system is only related to discrete time points, and the system state changes only when events occur at discrete time points. The important feature is that the state of the simulated system presents discrete changes. In discrete simulation, event is an extremely important concept, and event is the fact that causes discrete changes in the state of the system. The time point at which the event occurs becomes the event time point. It is reasonable to use the discrete event-driven model to simulate the network system, because the state of the network system generally only changes with the occurrence of discrete events such as the arrival o...

Abstract

When present network simulation software carries out mobile wireless sensor node data transmission simulation, support of mobile node pertinence is lacked, in simulation design, mobile route description of a mobile node is difficult, a simulation code compiling amount is large, and result output is tedious. Therefore, the invention provides a wireless sensor network emulator facing mobile node data transmission, and the wireless sensor network emulator supports the mobile node. An emulator reads a script to carry out initialization at an initialization phase; a system adds an initialization event to an event queue to promote whole simulation; a scheduler reads an event at a head part of an event queue, and delivers the event to a related event processing program for processing; in a scheduler operation period, according to time generated by a node model and an energy consumption model, the emulator carries out simulation on node sending and receiving messages, a mobile behavior of the mobile node and energy consumption of the node, and according to a type of a processing event, formats corresponding event information and outputs the information to a tracking file. When simulation is finished, running condition of a network is outputted.
