MAC protocol realization method and device for adjusting working cycles based on energy states

Abstract

The invention discloses an MAC protocol realization method and device for adjusting working cycles based on energy states. The method comprises the steps that when polling is carried out each time, a sink node sends polling packets to all sensor nodes; wherein data in the polling packets comprises the number of the energy collection type sensor nodes, the number of battery power supply type sensor nodes and the residual energy of all sensor nodes before the polling is started this time; and after receiving the polling packets, the active senor nodes update sleep duration in own working cycles according to the polling packets. According to the MAC protocol realization method and device for adjusting the working cycles based on the energy states disclosed by the invention, the battery power supply type sensor nodes are enabled to integrally have relatively long sleep duration proportions, the energy collection type sensor nodes with relatively poor energy states are enabled to have relatively long sleep proportions, so the energy consumption of the whole network is balanced, the reliability of the network in the relatively long time is ensured, and the transmission performance is improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for monitoring file data sent by QQ. Background technique [0002] With the development of science and technology, people rely more and more on the Internet, and the problem of network leaks has also emerged. Major companies: various departments have to control the use of the network by employees to prevent employees from leaking some confidential information. . [0003] At present, there are many network management and control tools on the market, most of which are used to control the computer, and the client needs to be installed on the computer, and the data collected by the client is sent to the monitoring terminal for monitoring. There are bound to be many problems in this way: 1: The client needs to be installed in each device to be monitored, and the operation is too cumbersome; 2: After the client is uninstalled or disabled, it will no longer play a...

Problems solved by technology

There are bound to be many problems in this way: 1: The client needs to be installed in each device to be monitored, and the operation is too cumbersome; 2: After the client is uninstalled or disabled, it will no longer play a monitoring role; 3: The client Installed in the system itself is protected by the authority control of the operating system and anti-virus software, which is not conducive to data capture 4: Since the client needs to run in the background, sending data to the server will inevitably increase power consumption. Not available on mobile devices

[0004] QQ is a very popular social tool, and it is often used as a tool for transferring files. However, most management and control tools do not monitor QQ file transfer data, which is also a gap in network management and control.
