Embodiment Construction

[0054] to combine figure 1 The steps to illustrate the implementation method of the cross-layer wireless sensor network medium access control protocol are: network initialization, periodic listening, and periodic sleep; where the time of each periodic listening is fixed, and each periodic listening includes three steps: synchronization, request and response A time window; the sleep time of each cycle sleep is fixed when no business occurs in the area with the largest node communication interference. Once there is a business, the node can perform data transmission or adaptive wake-up or forced wake-up; the following describes the working time of each stage specific settings.

[0055] The purpose of the network initialization phase is to make the network nodes form a virtual synchronous cluster. In order to expand the range of virtual synchronization clusters, the present invention increases the random waiting window time for nodes to declare synchronization messages, and reduc...

Abstract

The invention relates to a method for realizing cross-layer wireless sensor network medium access control protocol. The method mainly arranges a plurality of nodes as forcible arousing nodes after the wireless sensor network nodes enter a periodic sleeping time so as to find a node in a future communication path from the nodes, thus realizing multi-hop transmission of one interception / sleeping periodic data. The method is mainly used for solving the problems that the wireless sensor network which is sensitive to time delay and has little service quantity can not meet the channel to access a waiting time delay.

Description

technical field [0001] The invention relates to a method for realizing a cross-layer wireless sensor network media access control protocol, which belongs to the field of wireless sensor networks. Background technique [0002] Wireless sensor network is one of the IT technologies that will have a significant impact on human life after the Internet. The wireless sensor network integrates the logical information world and the objective physical world, thereby changing the way of interaction between human and nature and expanding the ability of human to recognize the world. As a ubiquitous sensing technology, wireless sensor networks are widely used in military, environmental, medical, household and other commercial and industrial fields; in special fields such as space exploration, anti-terrorism, and disaster relief, it also has unique technical advantages. [0003] A wireless sensor network is a fully distributed system without a central node. It has many similarities with a...
