Problems solved by technology

[0003] However, in many existing location-based routing protocols, in order to obtain the location of the destination node, a server is required to provide location information of all nodes, the amount of data maintained is large, and the query time is long

specific Embodiment approach

[0059] 1. Prepare the corresponding role ID allocation plan according to the organization establishment, scale, etc.; each organization member will be assigned a role ID. In this embodiment, an ad-hoc network is deployed in a battalion, and the establishment is divided into four levels: battalion, company, platoon, and squad. The example scenario is shown in FIG. 1 . The organizational structure of a battalion is: a battalion includes three companies, numbered respectively: 1 company, 2 companies, and 3 companies. A company includes three rows, numbered respectively: 1 row, 2 rows, 3 rows. The three rows of 1 company are numbered as follows: 1 company 1 row, 1 company 2 rows, 1 company 3 rows. A platoon includes three classes, numbered respectively: Class 1, Class 2, and Class 3. For example, there are three shifts in 1 row and 3 rows, and the numbers are: 1 shift in 1 row and 3 rows, 2 shifts in 1 row and 3 rows, and 3 shifts in 1 row and 3 rows. A squad has a squad leade...

Abstract

The invention relates to a position-aided high dynamic wireless router and a routing method for establishing a non IP network and is used in a wireless self-organized network. The router includes: a receiver; a transmitter; locating equipment acquiring receiver position information, connected with the receiver and providing with geographical data corresponding with the geographical position of the receiver; application software in the equipment; a local information table of the equipment; a neighbor equipment table of the equipment; and a memory used to store the application software, the local information table and the neighbor equipment table. The routing method of the invention includes the following steps: 1) a role allocation and maintenance module perform the role ID allocation and role ID change of the equipment; 2) an information table maintenance module creates, updates and inquiries the information table in the equipment; 3) a route module creates, updates and inquiries the neighbor equipment table in the equipment and completes the information transmission between the equipment. The invention avoids great amount of maintenance expenditure caused by high dynamic change of the network, effectively controls information flooding, reduces the memory needed by maintenance position information and is applicable to the network with large scale and high dynamic node change.

Description

technical field [0001] The invention relates to a highly dynamic wireless router and a routing method for constructing a non-IP network with location assistance, and belongs to the technical field of wireless ad hoc network routing. Background technique [0002] Traditional Ad Hoc routing protocols mainly include DSR (Dynamic Source Routing), AODV (Ad-Hoc0n-demand Distance Vector Routing), DSDV (Destination-Sequenced Distance-Vector) and FSR (Fisheye State Routing). Due to the broadcast nature of route discovery and when the path is long, the route is easily invalidated, resulting in a large amount of routing overhead, so one of their main disadvantages is that they are not suitable for medium-to-large-scale, medium-to-high-speed movement occasions. Therefore, many location-based routing protocols are proposed to solve the shortcomings of traditional routing protocols. The location-based routing protocol uses the location information of nodes to complete data forwarding, an...
