Problems solved by technology

(2) Limited resources: the working energy provided to the mobile host in the Ad hoc network is limited; on the other hand, the network itself provides limited bandwidth and the conflict and interference between signals, so that the limited transmission bandwidth available to the mobile host will be far less than the theoretical maximum bandwidth
(4) Low security: Ad hoc network nodes communicate through wireless channels, and the transmitted information is very vulnerable to various attacks such as monitoring, retransmission, tampering, forgery, etc.
Because the control packet formats of each routing protocol are different, generally speaking, networks using different routing protocols cannot communicate normally.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the implementation process of the mechanism, but the implementation process should not be construed as limiting the present invention.

[0018] The purpose of this mechanism is to integrate two wireless ad hoc networks running different routing protocols into one network, unify routing protocols, and resolve conflicting IPs, so as to facilitate long-term communication between the two networks. In this mechanism, we stipulate that the node that detects the other party's network is the border node, the border node that first detects the other party's network and sends a fusion request message is the active node, and the border node of the other party's network that communicates with it is the passive node.

[0019] In order to complete the fusion, information exchange between nodes is required. For this purpose, we define the following message types:

[0020] Fusion request message: the message sent...

Abstract

The present invention provides a fusion mechanism of wireless self-organizing network operating different routing protocols. The aim of the mechanism is self-adaptingly execute network fusing through perception in the gradual closing process of two networks. The node finds the other network through real-time interception. The network authentication is executed through handshaking information. A uniform routing protocol is confirmed through a priority comparing algorithm and the conflicted IP is discovered through Hash algorithm. The mechanism simply and effectively realizes the fusion of two networks and finally unifies routing protocols. The IP conflict is settled and the long-time communication of two networks is facilitated.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a wireless self-organizing network, that is, an Ad hoc network. Specifically, it is a wireless self-organizing network fusion mechanism that runs different routing protocols, which can adaptively complete network fusion, unify routing protocols, and resolve IP conflicts. Background technique [0002] Ad hoc network is a temporary autonomous wireless system composed of stationary or mobile nodes. It does not rely on the existing network infrastructure, and relies on the mutual cooperation between nodes to complete the network interconnection between nodes. Ad hoc networks are mainly used in the military, emergency occasions and temporary occasions where wiring is not easy. At present, the Ad hoc network is gradually developing towards the commercial environment, such as sensor network, virtual classroom and home network. [0003] The characteristics of the Ad hoc network ar...
