Method and node equipment for implementing certain access of network in wireless gridding network

Abstract

The invention discloses a method of implementing deterministic accessing in wireless grid network. Each node in network shares period interval time SI of time slot MDAOP selected by deterministic accessing mode of distribution grid. The said node determines the time slot MDAOP to be distributed based on SI and the MDAOP time slot information is sent to a neighbor node of establishing deterministic accessing with the said node. The said neighbor node establishes deterministic accessing with the said node based on the received MDAOP information. The invention also provides a wireless grid network node device, composed of a information sending and receiving unit, a period interval time setting unit, a time slot assignment unit. The said invention can prevent the nodes from generating collision on distributing the MDAOP time slot and reduce the competition of node on accessing to the channel.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and node equipment for realizing network deterministic access in a wireless grid network. Background technique [0002] The development of wireless network technology is changing with each passing day. Various 802.11x standards are constantly being updated, and new wireless network architectures and technologies are constantly being proposed, such as WLAN Mesh (wireless mesh network). Its core guiding ideology is to make each node in the network Both can send and receive signals, and the wireless Mesh network is also called a multi-hop network. In a traditional WLAN, each client accesses the network through a wireless link connected to an AP (access point). If users want to communicate with each other, they must first visit a fixed AP. This network structure is called called a single-hop network. In a wireless Mesh network, wireless device nodes can act as...

Problems solved by technology

[0027] The main purpose of the present invention is to provide a method for realizing network deterministic access in a wireless mesh network, so as to solve the problem that existing MDA schemes have conflicts when allocating idle time slots and do not support asynchronous Mesh nodes, and avoid multiple Conflicts occur when hopping nodes allocate MDAOP time slots, and deterministic access to Mesh is realized in asynchronous Mesh nodes, reducing competition when Mesh nodes access channels
