Ad Hoc network Construction method based on OMAP 3530Mini development board

Abstract

The invention relate to an Ad Hoc network construction method based on an OMAP 3530Mini development board which realizes the Ad Hoc network by using the OMAP 3530Mini development board as a hardware platform and using a wireless local area network card as hardware support. The method comprises the following steps of: manufacturing an embedded kernel suitable for the OMAP 3530Mini development board in the development environment of Ubuntu, adding necessary function in the kernel to adapt the requirement of the Ad Hoc network, manufacturing a simple root file system to finish the basic function of the file system, compiling the driver of the wireless local area network card in an intersecting way so that the driver can be successfully operated on the development board, driving the wireless local area network card to operate, compiling a wireless configuration tool in an intersecting way to perform network configuration on the wireless local area network card, transplanting an AODV (Ad Hoc On-demand Distance Vector) routing protocol so that a node in the network can perform multi-hop communication so as to finally construct the Ad Hoc network, performing point-to-point communication test and multi-hop test on the constructed network, and performing tests of functions for word communication, voice communication, ftp file transmission and the like.

Description

technical field [0001] The invention belongs to a method for realizing an Ad Hoc network in the technical field of wireless communication, and in particular relates to how to realize a method for building a wireless self-organizing network on a specific hardware platform OMAP3530Mini development board. Background technique [0002] The mobile Ad Hoc network is composed of a group of wireless mobile nodes. It is a network system that can be quickly deployed without relying on the existing fixed communication infrastructure. It is a self-organizing and self-healing network without any central entity; Network nodes cooperate with each other, communicate through wireless links, exchange information, and share information and services; network nodes can enter and leave the network dynamically, freely, and frequently without prior warning or notification, and Communication with other nodes in the network will not be disrupted. [0003] Ad Hoc network has the following characteris...

AI Technical Summary

Problems solved by technology

3. Bandwidth limitations and varying link capacities

6. Node energy is limited

7. The unidirectionality of the channel

However, the above-mentioned networks are only applicable to areas with existing backbone networks. For areas where no backbone network exists or where the backbone network has been For cities, battlefields and other special places destroyed by other disasters, the above-mentioned mobile communication network cannot meet the demand
