Embodiment

[0050] like figure 2 As shown, there are a total of 9 nodes in the network in the example, the circle represents the Internet node, the triangle represents the mobile ad hoc network node, and its ip addresses are 192.168.1.1, 192.168.1.2 ... 192.168.1.9 For the convenience of description, we The 9 nodes are numbered, the 4 Internet nodes are numbered 1 to 4 respectively, and the 5 mobile ad hoc network nodes are numbered a to e respectively. According to the actual needs, we specify the value of n as 2, then the gateway node requires that the number of neighbors is greater than or equal to 3.

[0051] In the neighbor detection phase, each node broadcasts hello messages and processes the received hello messages, thereby generating the neighbor table of the node, and sending it to the administrator node through broadcasting. The administrator node gets the following information: image 3 An overall neighbor table is shown.

[0052] In the generation stage of the relationship ...

Abstract

The invention discloses a route fusion method for a mobile ad hoc network and Internet mixed environment. The method includes detection of neighbor nodes, establishment and maintainment of a relational network, assessment of credit rating, establishment of sub-networks and forwarding of gateway packets. According to the invention, the intercommunication between the mobile ad hoc network and the Internet is realized, and the message intercommunication between the nodes using different routing protocols is realized, so that the mobile ad hoc network and the Internet are allowed to respectively use the routing protocols suitable for the own network environment, and the routing and transmission efficiency of data is improved.

Description

technical field [0001] The invention relates to a mobile ad hoc network (Mobile Ad Hoc Network) technology, in particular to a route fusion method oriented to a mixed environment of the mobile ad hoc network and the Internet. Background technique [0002] Mobile ad hoc network is a network that combines mobile communication and computer network. The information exchange of the network adopts the packet switching mechanism in the computer network. The user terminal is a portable terminal that can be moved. Each user terminal in the ad hoc network has both Both router and host functions. As a host, the terminal needs to run various user-oriented applications, such as editors, browsers, etc.; as a router, the terminal needs to run the corresponding routing protocol, and complete the forwarding and routing maintenance of data packets according to the routing strategy and routing table. Nodes are required to implement a suitable routing protocol. The goal of the ad hoc network ...
