Wireless sensor network (WSN) emulation system

Abstract

The invention discloses a wireless sensor network (WSN) emulation system. The emulation system comprises a user interface, a bottom module library, a node member library, an emulation environment scene library, a running object library, a parameter configuration library, a node composition relation library, a service database, a packet information library, a packet head information library, a module registering unit, a module selecting unit, a module assembling unit, a parameter setting unit, a topology data generating unit, a service scheduling unit, a display unit and a result statistic unit. Aiming at the characteristics that the WSN takes data as the center and is application-oriented, the system emulates the communication protocols in the WSN environment and multiple kinds of application based on the WSN and can undergo modular extension as required. The system can synchronously count the energy consumption of each sensor node through an energy model thereof during the WSN emulation test so as to objectively and actually provide reference technical indexes for research schemes.

Description

technical field [0001] The invention belongs to the field of wireless sensor network (WSN, Wireless Sensor Networks) simulation technology, and in particular relates to a simulation system for simulating communication protocols and various sensor network-based applications under the WSN environment. Background technique [0002] At present, there are several general-purpose network simulation systems that can be used for WSN, such as NS-2 (network simulator-2), OPNET, TOSSIM (TinyOS simulator), etc., which have become the mainstream simulation systems for WSN research, but these mainstream general-purpose simulation systems The system has different degrees of defects in the simulation of WSN: [0003] (1) NS-2 is a discrete event simulation tool for network research, which can simulate complex network environments such as wired, wireless, local connections, and satellite connections. NS-2 can simulate various network protocols such as TCP protocol, routing algorithm, and mu...

AI Technical Summary

Problems solved by technology

Therefore, to implement WSN simulation on a general network simulation system, a large number of protocol addition work and cross-layer protocol modification will inevitably occur, which increases the difficulty and workload of simulation

[0009] (3) Some simulation systems do not evaluate the energy consumption of wireless sensor nodes, and energy consumption is just a very critical performance indicator in WSN research

[0010] (4) Most general-purpose simulation systems only aim at the description and simulation of the underlying protocol, and cannot realize the algorithm simulation of the abstract application layer
