Embodiment Construction

[0066] The network address initialization configuration process of the method for automatically assigning IP addresses of mobile ad hoc network nodes based on neighbor agents is as follows:

[0067] 1) There is only one node A in the initial network, and a neighbor request NRQ (Neighbor Request) message is sent through a one-hop broadcast to search for adjacent nodes.

[0068] 2) Since it is in the network initialization stage, node A does not receive any response message, then node A selects the internal IP address for self-configuration. Node A can determine the network identification length NIDL by manual setting or by default, and randomly generate the network identification number ID. The host identification length HIDL can be calculated by subtracting the network identification length NIDL from the IP address length L, and the host identification number is set to 1.

[0069] 3) Determine the optional base system according to the length HIDL of the host identification nu...

Abstract

The automatic address allocation method of mobile mobile ad hoc network adopts the IP address hierarchical allocation mode based on neighbor agent and non-conflict detection. The address allocation information has genetic characteristics, and the variable-length available IP address control word is used to control the IP address allocation process. The method includes mobile ad hoc network address initialization configuration, IP address automatic allocation protocol, IP address allocation control process, IP address relay protocol, IP address pool recovery protocol, network merge transformation and network segmentation transformation. Conflict detection IP address hierarchical allocation mode, address allocation information has genetic characteristics, using variable-length available IP address control word, flexible control of the allocation process of available IP address space, effectively avoiding address allocation conflicts, no need for address conflict detection, Improve the efficiency of address allocation, reduce the use of multicast or broadcast packets in the process of address allocation, reduce resource consumption, and are applicable to various versions of IP address allocation.

Description

technical field [0001] The invention relates to a mobile ad hoc network IP address automatic configuration method, which belongs to the technical field of mobile ad hoc networks. Background technique [0002] Mobile Ad Hoc Networks (MANET, Mobile Ad Hoc Networks) is composed of a group of wireless mobile nodes, does not rely on the existing fixed communication network infrastructure, no central entity, self-organized multi-hop network. Each network node can enter and leave the network dynamically, freely, and frequently, and the nodes communicate with each other through wireless links. Because the mobile nodes are not fixed, the wireless link is unstable and the bandwidth is limited, and there is no central management device, etc., the automatic allocation of IP addresses in the MANET network environment is more difficult and complicated than the wired network.
