| This dissertation is about the project of Information Transmission Subsystem (ITS) Development, a project of the National High-Tech Research and Development Program of China. The main task of this project is doing research on the wireless self-organized network technology which is used in the information transmission subsystem of field forces.To accord with the hierarchical organization of army, the ITS is organized with a 3-layerd network structure. Each layer is made up of several wireless self-organized subnets (the top-level layer has only one subnet). Each communication node in the network has not only wireless interfaces but also a wired Ethernet interface which can connect a wired subnet. Layered self-organized networks have two kinds of self-organized routing algorithms. One is used in the subnet; another is used between two layers. The design of self-organized routing algorithm for the ITS based on MANET is the main part of this dissertation.In this self-organized network, each subnet follows the tree structure based on Kernel Tree Routing Protocol (KTRP). Because the network structure in KTRP is 2-layered formed with wireless routers and wireless hosts, some necessary modifications should be made according to the network topology and node attributes that this project needs. Besides, how to achieve the self-organization and routing between two layers making use of kernel tree structure in subnet is the emphasis in this self-organized routing algorithm research.First, it gives a snapshot of some typical self-organized routing protocols in MANET. Then the design of self-organized routing algorithm based on KTRP is elaborated as the main part of this dissertation, including the choosing of key nodes, the main algorithm modification of KTRP to accommodate with the interior routing in subnet, the access flow between two layers, primary packet formats, tables, and IP routing algorithm. At last, the simulation model of the self-organized routing algorithm... |
