Problems solved by technology

However, with the increase of mobile users, the amount of routing calculations is becoming more and more huge, especially in some large-scale occasions such as New Year's Eve party, because there are too many clients in the same area, resulting in a heavy burden of communication, even lead to system paralysis

Embodiment Construction

[0015] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments are specifically cited below, and in conjunction with the accompanying drawings, the detailed description is as follows:

[0016] Figure 1A A schematic diagram of a wireless communication network 10 according to an embodiment of the present invention is shown. The wireless communication network 10 has eight nodes such as MH1 to MH8, and uses DSDV algorithm to transmit routing information. Wherein, for each node, the DSDV algorithm maintains a routing table (routing table) for recording relevant information reaching each node. For example, for an MH4 node, its routing table can be as follows Figure 1B shown.

[0017] exist Figure 1B In , the routing table is composed of eight routing items, which are the routing items of nodes MH1 to MH8 respectively. Among them, each routing item includes five columns, whic...

Abstract

The invention discloses a wireless communication network and a routing method. The wireless communication network comprises a first node and a second node, wherein the first node is used for transmitting a first routing message and is provided with a first routing table; the first routing table comprises a first routing item corresponding to a destination node; the first routing item comprises a first sub-node field; the second node is used for generating and transmitting a second routing message according to the first routing message; and the second routing message comprises a second parent node field which is marked as the first node for transmitting the first routing message, wherein the first node is further used for receiving the second routing message and storing a first mark in thefirst sub-node field included in the first routing item after the second parent node field included in the second routing message is marked as the first node, wherein the first mark represents the second node for transmitting the second routing message.

Description

technical field [0001] The invention relates to a wireless communication technology, in particular to a wireless communication network and a routing method which can reduce routing burden. Background technique [0002] In the mechanism of wireless communication, the routing information is transmitted between mobile clients (nodes) through the planning of the node sequence distance vector (Destination-Sequenced Distance-Vector, DSDV) routing algorithm, so that each node can understand the communication The path to any destination node and related information. In order to achieve fast and efficient communication, the DSDV routing algorithm will plan the shortest path to a specific destination node for each node. However, with the increase of mobile users, the amount of routing calculations is becoming more and more huge, especially in some large-scale occasions such as New Year's Eve party, because there are too many clients in the same area, resulting in a heavy burden of co...
