Embodiment Construction

[0035] One. Routing method overview of the present invention

[0036] The existing mainstream Ad Hoc routing protocols, such as DSR, AODV, DSDV, etc., cannot effectively support multi-rate communication, mainly because they select routes based on the principle of minimum hops. The final generated routes mainly contain long-distance links with low rates. Nodes sending data on this route will not have the opportunity to use high-speed communication, so they will not be able to use multi-rate transmission capabilities.

[0037] The method proposed by the invention is to optimize each member link of the minimum hop route, and divide the long-distance low-speed link into a link set composed of a plurality of short-distance high-speed links. When data is sent along routes made up of these short links, the equivalent total transfer rate is higher than that achievable by direct data transfer over the corresponding long-distance links.

[0038] In order to be able to realize the abov...

Abstract

The method includes following steps: through adding sub-layer functional unit in local route between network layer and data link layer, the route figured out by network layer is optimized; the route contains multi high speed short link divided up from a low speed long distance link; these short links build up new route to transmit data and support multi speed transmission; meanwhile the sub-layer of local route also needs to renew the internal link state table and neighboring node state table in order to provide message parameter for next optimization of route.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a mobile Ad Hoc network function layer structure and routing method that can support multi-rate transmission. The Ad Hoc network is a multi-hop, temporary autonomous system composed of a group of mobile terminals with wireless transceiver devices, which can be used in special occasions such as disaster relief, field inspections, and temporary meetings. Background technique [0002] With the continuous development of information technology, people's demand for mobile communication is getting stronger and stronger. In recent years, mobile communication technology has been rapidly developed and popularized, and mobile communication technologies such as cellular mobile communication systems, wireless local area networks, and Bluetooth technology have emerged one after another. The emergence of these technologies has greatly facilitated people's lives, and at the same time promote...
