Problems solved by technology

However, the dynamic change of the MANET topology makes it impossible to find a stable DHCP server in the MANET, so the centralized address automatic configuration method of DHCP cannot be used in the MANET
In addition, IPv6 also provides a stateless address autoconfiguration protocol [3] S.Thomson, T.Narten, "IPv6 Stateless AddressAutoconfiguration", RFC2462, 1998, but it can only be used in single-hop networks, and cannot adapt to multi-hop networks. jumping MANET

Embodiment Construction

[0066] The address automatic configuration method in the mobile ad hoc network, its configuration process is as follows:

[0067] Step S1: After the automatic address configuration starts, a temporary address and a tentative address are generated;

[0068] Step S2: broadcast AREQ to the network, and wait for the arrival of AREP;

[0069] Step S3: The MANET node receives the AREQ, and processes it according to its own IP address, the address and status in the routing table, and the temporary cache record. If it finds that the experimental address is duplicated with its own IP address, it sends the AREP to the requesting node;

[0070] Step S4: The MANET node receives the AREP, and processes it according to the tentative address requested by itself. If the address in the AREP is found to be the same as the requested address, a new tentative address is generated, and repeated address detection is performed again.

[0071] figure 1 The processing steps of each event are as foll...

Abstract

This invention relates to a method for automatically configuring address in MANET which combines itself with AODV route to increase repeated address test efficiency including: first of all, the s, a node of MANET, generates a temporary address for transmitting address configuration information and generates an experiment address then to broadcast AREQ and test the uniqueness of the requested address. The nodes who got the AREQ should refresh the route lists, if MANET node finds its own IP address or that in the route list is the same with the adder, that shows the adder is used. AREP is broadcast to s which generates a new address after receiving AREP and repeats the adder test. If s does not receive AREP, it assigns the adder to netcards.

Description

technical field [0001] The invention belongs to the technical field of mobile ad hoc networks, and relates to an address automatic configuration method in the mobile ad hoc network. Background technique [0002] MANET (Mobile Ad Hoc Networks) is a wireless multi-hop network without a base station. It is a point-to-point self-creating, self-organizing, and self-managing network with a highly dynamic topology and arbitrary movement of nodes. Literature [1] Ramanathan R, Redi J, "A Brief Overview of mobile Adhoc Networks: Challenges and Directions", IEEE Communications Magazine, 50 th Anniversary Commemorative Issue [C], 2002. AODV (Ad hoc On-demand Distance Vector) is an on-demand driven routing protocol in MANET [2] C.Perkins, "Ad hoc On-Demand Distance Vector (AODV) Routing", RFC3561, July 2003. The use of address automatic configuration technology in MANET can reduce the cumbersome manual configuration of users and enhance the flexibility and convenience of MANET network...
