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

An auto-allocation method of addresses of mobile ad hoc networks adopts an IP address stratified allocation mode based on neighbour proxy collision-free detection, address allocation information is provided with hereditary property; usable IP address control word which can become long is adopted to control the process of IP address allocation; the method comprises mobile ad hoc network address initialization configuration, an IP address auto-allocation protocol, an IP address allocation control process, an IP address trunking protocol, an IP address pool recover protocol, network merger and transformation and network partitioning and transformation; the invention adopts the IP address stratified allocation mode based on neighbour proxy collision-free detection, the address allocation information is provided with hereditary property, the usable IP address control word which can become long is adopted to flexibly control the allocation process of IP address space, thus effectively avoiding address allocation conflict, dispensing with address conflict detection, improving address allocation efficiency, reducing use of multicast or broadcast message in the process of address allocation, lowering resource consumption, and being applicable to allocation of IP addresses of multiple versions.

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.
