Embodiment Construction

[0054] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] Figure 1 is the hardware architecture of the simulation platform used to simulate the mobile ad hoc network. The platform consists of a control node and several experimental nodes, which are connected through high-speed switches. Each experimental node is equipped with a wireless network interface, which is connected to an external antenna through an SMA interface, and an adjustable RF signal attenuator with dual SMA interfaces is inserted between the wireless network interface and the external antenna, such as: BOWEISZZ007 program-controlled step attenuation device.

[0056] Figure 2 is the control node software architecture in the simulation platform. The "user operation interface" provides the user with an experimental setting input interface. This module samples the user-defined mobile ad hoc network scene time, and then transmits...

Abstract

Using application - interface isolation technique, the method fixes up mapping relation between nodes to be simulated and experiment node. Based on mapping relation of nodes, experiment node dispatches data packets of application program to realize simulation of self-organization network. The invention deploys mapping relation of nodes at sampling time on different wireless nodes on simulation platform to retain characteristic of distribution operation of application. Meanwhile, the method combines the technique with damping control for radio frequency signal to obtain high simulation validity for two features including wireless link of transmission characteristic, and node movement in mobile self-organization network. The invention guarantees better validity of simulation.

Description

technical field [0001] The invention relates to a mobile ad hoc network technology, in particular to a method for simulating a mobile ad hoc network. Background technique [0002] Mobile Ad-hoc NETwork (MANET) is an autonomous system composed of nodes that can move arbitrarily, and is a wireless multi-hop network with dynamically changing topology. Compared with the existing wireless cellular network (Cellular Networks) and wireless local area network (Wireless LAN), it has the advantages of no pre-deployment, networking anytime and anywhere, self-organization and self-maintenance. [0003] In recent years, the research and development of protocols related to mobile ad hoc networks has continued to be hot. Protocol evaluation is an important link in the process of network protocol design and development, which directly affects the quality and efficiency of network protocol design and development. Simulation, emulation, and real-world experiments are the three main approache...
