Implementation method for intelligent building up network among wireless devices under wireless network grids

Abstract

The method of automatic building and maintaining route under wireless environment includes steps: wireless device sends out device detection packet including forwarding table and lifetime of packet etc. timely in broadcast mode, the forwarding table in use for recording IP addresses of all devices for forwarding a message, and the life time of packet in use for marking forwarding number; other wireless devices received detection packet carries out wireless symmetry detection, symmetrical route is continuous to be executed, otherwise detection packets are discarded; based on content of forwarding table, information of this device is recorded in tables of direct accessible, indirect accessible or discard; based on forwarding table and life time information, wireless device forwards or discards device detection packet; based on source device direct accessible and indirect accessible tables configures directly or through algorithm configures route from this device to target device.

Description

technical field [0001] The invention relates to wireless network technology, more specifically to a method for realizing intelligent networking among wireless devices in a wireless grid. [0002] The wireless grid referred to in the present invention is a logical entity composed of a group of wireless devices and the services issued by them. Multiple wireless devices and services work in coordination within the grid and exhibit consistent behavior to the outside. Users can access the entire logical grid without caring about the details of a certain device or a certain service. A wireless device in a wireless grid refers to a device with radio frequency transmitting and receiving functions. It has a central processor responsible for processing user operations of wireless devices and responding to access requests from other wireless devices. High-end wireless devices may also have information display functions and the ability to connect other peripherals. For example, mobile p...
