example 1

[0038] Example 1: Assume that a certain route (hereinafter referred to as route 1) accesses area network 2 through routing switching node 2, and diffuses to area network 1 through routing switching node 1, and calculates the comprehensive routing cost of route 1 as follows:

[0039] Let the access interface of route one access area network 2 be the X interface of route switching node 2 (the described X interface belongs to area network 2), establish route one at the access routing expense of described X interface as k 11 , let the lowest intra-area network cost from routing node 2 to routing node 1 in area network 2 be k 12 , then the comprehensive routing cost K of route 1 1 =k 11 +k 12 ; where k 11 、k 12 All can be calculated according to the method of the OLSR routing protocol in the prior art.

example 2

[0040]Example two: assume that a certain route (hereinafter referred to as route two) accesses area network 3 through route switching node 4, and after said route two passes through area network 1, spreads to area network 2 through route switching node 1, and calculates the value of route two as follows Integrated routing overhead:

[0041] Let the access interface of route two access area network 3 be the Y interface of route switching node 4 (the Y interface belongs to area network 3), set the access routing cost of route two at the Y interface as k 21 , let the lowest intra-area network cost from routing switching node 4 to routing switching node 3 in area network 3 be k 22 , let the lowest intra-area network cost from routing switching node 3 to routing switching node 1 in area network 1 be k 23 , then the comprehensive routing cost K of route two 2 =k 21 +k 22 +k 23 , where k 21 、k 22 、k 23 All can be calculated according to the method of the OLSR routing protocol...

Abstract

The invention provides an organization method based on an OLSR routing protocol wireless network, and the wireless network comprises a plurality of routing switching nodes, and a single routing switching node comprises a plurality of interfaces. The organization method is characterized by comprising the following steps: 1) dividing a plurality of interfaces in a wireless network into a plurality of regional networks according to regions, then allocating regional ID numbers to the regional networks, and then allocating respective aggregation network segments to the regional networks; the organizing method of the wireless network comprises the steps of (1) establishing a plurality of local area networks; (2) carrying out routing information interaction on the plurality of local area networksaccording to the first method; (3) calculating a routing table. The organizing method of the wireless network can improve expandability, stability and high efficiency of the wireless network based onthe OLSR routing protocol.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a method for organizing a wireless network based on an OLSR routing protocol. Background technique [0002] The OLSR routing protocol is an optimized link state routing protocol proposed by the IETF MANET (mobile ad hoc network) working group for wireless mobile AdHoc networks. Since the agreement was announced in October 2003, it has undergone many improvements, refinements and enhancements. However, with the rapid development and large-scale use of narrowband wireless networks, especially ultrashort wave radio technology, the OLSR routing protocol has been unable to support it, resulting in a limited network scale and affecting its full application. [0003] Therefore, the wireless network based on the OLSR routing protocol has limited scale, poor scalability, insufficient convergence efficiency and low stability, which are problems that need to be solve...
