Problems solved by technology

The node mobility under the Ad hoc network is high, and the link status is unstable, which leads to drastic changes in the network topology compared with other networks. At the same time, when the network link status is unstable, different routing services are provided for business types. ; In addition, the high delay and low bandwidth of wireless links also limit the spread of routing information and the effectiveness of routing topology

Embodiment Construction

[0034] Wireless routing protocols generally have two modes: table-driven and on-demand. Table-driven uses the method of periodically sending routing messages to exchange routing information and establish a network topology. Real-time exchange of routing information to establish a network topology. As the means of routing information collection, the two methods have their own advantages and disadvantages, which are mainly reflected in the timeliness of routing information and the controllability of routing overhead. As an Ad hoc routing protocol, it provides differentiated services for services, which can reflect its advantages. Therefore, the key to wireless routing protocol design is to improve the timeliness of routing information, reduce routing overhead and provide differentiated business services.

[0035] The present invention adopts following means to realize above-mentioned design purpose:

[0036] 1) See attached figure 1 , add an intranet routing layer between the...

Abstract

The invention discloses a routing algorithm based on ultra short wave radio, including: an internal network routing layer is added between IP layer and MAC layer; the routing layer runs the compression algorithm of the link information and achieves the selection and the distribution of the optimal path; the beneficial technology effect of the invention lies in providing a simple routing algorithm with high betimes, controllable overhead, and with distinguishing business services.

Description

technical field [0001] The invention relates to a wireless network communication technology, in particular to a routing algorithm based on an ultrashort wave radio station. Background technique [0002] Ad hoc network is a wireless, multi-hop self-organizing network. The node mobility under the Ad hoc network is high, and the link status is unstable, which leads to drastic changes in the network topology compared with other networks. At the same time, when the network link status is unstable, different routing services are provided for business types. ; In addition, the high delay and low bandwidth of wireless links also limit the spread of routing information and the effectiveness of routing topology. Therefore, it is necessary to design a routing algorithm based on ultrashort-wave radio stations and adapt to Ad hoc networks, reduce routing overhead while satisfying the real-time nature of routing information, and provide differentiated services for businesses according to...
