Cross-layer route method of mobile self-organizing network based on minimum interference

Abstract

The invention discloses a cross-layer route method of a mobile self-organizing network based on minimum interference. Performance of a routing protocol is seriously influenced by channel competition and grouping collision in a mobile Ad Hoc network, and thereby performance of the network is influenced. In addition, the competition and the collision are become to be complicated and changeable caused by arbitrary movement of nodes. Therefore, the fact that the competition and the collision are analyzed to build an appropriate route under the condition of the arbitrary movement of the nodes is very important. The cross-layer route method based on the minimum interference is provided through length of time of the competition and the collision generated by each hop of the route and the forecast interference nodes. The cross-layer route method divides the interference nodes into two types, wherein one type of interference just influences the competition of channels and the other type of the interference not only influences the competition of the channels, but also enables grouping to produce the collision. Under the condition of overall consideration of the competition and the collision, the cross-layer route method of the mobile self-organizing network based on the minimum interference is capable of defining new routing judgment to build the route, building the route with the minimum interference and guaranteeing that the route is not frequently disconnected.

Description

technical field [0001] The invention relates to a cross-layer routing implementation scheme based on minimum interference in a mobile ad hoc network, which belongs to the technical field of communication. Background technique [0002] Mobile ad hoc networks (MANETs) are a kind of self-organized multi-hop wireless network without a center, and nodes can freely enter or leave the network as hosts and routers. However, due to the arbitrary mobility of nodes, the network topology changes frequently and is often unpredictable. So how to choose the route to the destination node has become an important and core problem in ad hoc network. Due to the unique characteristics of MANETs, ​​the cross-layer design of routing protocols has become an irresistible trend. The main idea of ​​cross-layer design is to use the correlation of each layer to increase the vertical communication between layers and reduce the horizontal communication between nodes. Reduce resource waste and improve ne...

Problems solved by technology

[0004] At present, there are few researches on cross-layer routing of mobile Ad Hoc networks based on competition and packet collision, and more are based on the number of neighbor nodes to judge the strength of interference , so there will be two problems: 1) For a node in the network, not all neighbor nodes will interfere with it, only the working nodes selected as routes to forward packets will interfere with it

2) Nodes must periodically send HELLO broadcast packets (without GPS device) to fully count neighbor node information, which not only increases the workload of nodes, but more seriously, the performance of the network will also be greatly reduced due to the periodic sending of broadcast packets

The inability to determine or estimate future network information based on past and current network information is a common defect of many routing protocols

If we know the movement model of the node, it will make it possible to solve the above problems
