Embodiment Construction

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] An Enhanced Guaranteed Time Slot (Enhanced Guaranteed Time Slot; EGTS for short) refers to a period of time and / or a channel allocated through negotiation between a sending node and a receiving node, where the sending node is adjacent to the receiving node. During this period of time and / or within the channel, only the sending node com...

Abstract

The embodiment of the invention provides a request sending method, a request sending system, an initial node, a middle node and a target node, and relates to the technical field of communication. The request sending method comprises the following steps that: the middle node receives an enhanced guaranteed time slot (EGTS) request which is broadcast by the initial node, wherein the EGTS request comprises a route find request which comprises a route identifier of a route from the initial node to the target node; when that the middle node receives the EGTS request at the first time is determined according to the route identifier, the route identifier in the route find request is recorded; the middle node adds an identifier of the middle node into the route find request, takes the identifier as a route record, and broadcasts the EGTS request so that the target node receives the EGTS request and acquires the route record in the EGTS request. By the embodiment in the invention, a route having a time delay guarantee between the multi-jump initial node and the target node is found in a wireless mesh network.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a method and system for sending a request, an initial node, an intermediate node, and a destination node. Background technique [0002] Wireless mesh (Mesh) network, that is, wireless mesh network, also known as multi-hop network, is a new type of wireless network technology that is completely different from traditional wireless networks. It is a wireless multi-hop mesh topology network with self-organizing , self-management, self-healing capabilities, and compatibility and interoperability with existing wireless networks. Wireless Mesh networks can be combined with multiple broadband wireless access technologies to form a wireless mesh network with multi-hop wireless links. This wireless mesh network can greatly increase the coverage of the wireless system, and at the same time improve the bandwidth capacity and communication reliability of...
