Embodiment Construction

[0060] A typical campus communication scenario can be deployed and implemented in the following ways. PCAgent and mobile phones are required to complete the ad hoc communication network composed of fixed entities and mobile entities, and realize the perception and communication functions of communication terminals, such as information query on catering and shopping, positioning in GIS and Web, and perception of preferential information of merchants. If at least two PCAgents are set, the PCAgent switching during the mobile phone movement can be displayed, that is, the terminal will select the PCAgent with the smallest delay for connection. At least two terminals can realize mobile instant communication between terminals, including text information and voice information.

[0061] 1. The configuration and requirements of the terminal are as follows:

[0062] 1). Mobile phones, PDAs, UMPCs and other portable in-vehicle devices that support WiFi functions.

[0063] 2).Fixed-wirel...

Abstract

The invention discloses a site sensing communication method of an ad hoc wireless network, which comprises the following steps that: 1) all mobile and fixed entities in the communication process are equipped with wireless terminals and set as an ad hoc mode, and directly communicate in a point-to-point peer mode without needing a base station or center to transfer; 2) when the entity terminals encounter, the identity is recognized through neighbor discovery, and if the restriction stipulated by the route is met, mutual communication is triggered; otherwise, the entity terminals can delay the transfer and cache the held information until the restriction is met or time is up to discard the information; and 3) a node of each entity terminal can issue the public information thereof or the place thereof; and when the entity terminals encounter, data information interaction is performed according to the communication process so as to realize mutual sensing and recognition of the entities on the site. The method disclosed by the invention has a small code space, a high information transfer submission rate and high expandability and invulnerability, realizes point-to-point direct sensing communication, can obtain the site information around the actual environment of each terminal, and can be applied to the induction of traffic information.

Description

technical field [0001] The invention relates to a wireless network, in particular to a point-to-point peer-to-peer communication and interaction method of wireless network nodes. Background technique [0002] In the transportation system, the necessary information interaction and communication between traffic participants, vehicles and even roads are of great significance to the effective, stable and safe operation of the system. In addition to relying on the information sources provided by the vehicle and public infrastructure to obtain vehicle and road condition information, if the driver can use the language of the vehicle to interact with other vehicles for necessary information, the information exchange, cooperation, and cooperation among drivers on the road can be realized. , Supervision, can realize vehicle collision avoidance, traffic congestion early warning, mutual inspection of vehicle conditions, mutual supervision of driving behavior, etc., effectively increase ...
