Adaptive Gateway Discovery Algorithm Based on Gateway Pheromone for Manet to Access the Internet

Abstract

The invention relates to a gateway pheromone-based adaptive gateway discovery algorithm for MANET accessing the Internet. The steps are: first, the link stability assessment method is used to select a stable link and predict whether the link is disconnected; second, the gateway pheromone is used to mark whether the node has the qualification to forward GWADV information, and the GWADV information is passed by The gateway, the node with the forwarding qualification and the source node are forwarded to the source node in the active area; third, periodically adjust the forwarding qualification of the node, adjust the active area, and make the active area automatically adapt to the topology change of the MANET, so that the GWADV The information is forwarded to the source node. The present invention has few nodes involved in forwarding, stable established routes, low control overhead, high overall performance of the network, strong adaptability, and no additional hardware requirements and energy consumption.

Description

technical field [0001] The invention belongs to the field of mobile ad hoc networks (MANET: MobileAdHocNetworks), and specifically relates to a gateway pheromone-based adaptive gateway discovery algorithm for MANET access to the Internet. Background technique [0002] Mobile Ad Hoc Networks (MANET: MobileAdHocNetworks) is a network composed of a group of mobile nodes with routing and forwarding functions, which can communicate in an environment without any communication infrastructure support. Communication between two nodes can be realized through multi-hop, and the intermediate node is not only a terminal node, but also has the function of routing and forwarding. [0003] The access of mobile ad hoc network to the Internet can expand the application of ad hoc network, and it is also a goal of the next generation 4G network to seamlessly connect all existing networks. Because the address structure in MANET is not compatible with the IP address structure, the two cannot be ...

AI Technical Summary

Problems solved by technology

[0006] 2. Although the hybrid gateway discovery algorithm can reduce the control overhead to a certain extent, once the TTL parameter is determined, all nodes in the active area will still periodically generate a large number of control packets

[0007] 3. Due to the mobility of nodes in MANET, the network topology is unstable

The current gateway discovery algorithm does not take into account the selection of stable routes when establishing routes to gateways
