Embodiment Construction

[0014] The technical solutions of the present invention will be described in more detail below in conjunction with the accompanying drawings and specific implementation examples.

[0015] The present invention proposes a node that delays the occurrence of business data and its forward and backward directions (the forward direction refers to the direction from the node to the central control node, and the backward direction refers to the direction from the node to the tail node). When the data transmission is completed, several neighboring nodes The mechanism for entering the hibernate state. When the above-mentioned nodes are going to enter the periodic sleep and wake-up state after the business data transmission is completed, their working hours should be appropriately extended, so that if the node that next generates business data transmission falls within the above-mentioned nodes in a short period of time, the purpose of fast wake-up can be achieved .

Abstract

The invention provides a link hibernation method for a wireless sensor multi-hop network chain-like topological structure. Supposed that all nodes before the Kth node in a link are in a work state during business data transmitting, and all the nodes after the Kth node are in a periodical hibernation awakening state. The inherent hibernation delay time of the nodes is T2, that is, the nodes enter the periodical hibernation awakening state if no business data is transmitted in the time period T2. When the Kth node finishes the transmission of the business data, the Kth node and all nodes which are K/i before the Kth node enter the periodical hibernation awakening state after delaying a time period T3, and the other nodes enter the periodical hibernation awakening state according to normal conditions, wherein i is bigger than or equal to 1 and smaller than or equal to k. When business data transmitting is carried on in a certain local area in the link frequently in short time, the purpose of quickly awakening the link can be achieved, so that the timeliness and the reliability of the system are improved.

Description

technical field [0001] The invention relates to a link dormancy method of a wireless sensor multi-hop network chain topology structure, belonging to the field of wireless communication. technical background [0002] The wireless chain communication system is designed for the band-like application scenarios where the communication area is chain-like topology. It has its unique advantages in the application scenarios that require band-like coverage, such as wind-resistant sand forests, coastal beaches, and border defense perimeters. Currently, it has Extensive market demand. [0003] When the link enters the dormant state because there is no business demand, delay the period of the node in the link that is far away from the master node from entering the dormant state according to certain rules, which can solve the problem that a certain local area in the link frequently The problem of frequently waking up the link due to business data transmission. [0004] None of the exist...
