Abstract

The invention discloses a method and system for realizing a virtual special network platform based on a multi-NAT (Network Address Translation) pure IPv6 (Internet Protocol Version 6) network. The method comprises the steps of S1, an encryption tunnel between a client subsystem and a server subsystem; S2, the client subsystem monitors and resolves user data and forwards the user data satisfying a predetermined condition to the encryption tunnel; S3, the server subsystem reads the user data from the encryption tunnel and carries out protocol analysis on the user data and puts the user data based on a dns (Domain Name System) protocol and / or http protocol to different queues for forwarding; and S4, the server subsystem returns a dns resolving result and / or an http response message to the client subsystem through the encryption tunnel and moreover adds the messages to a cache.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a MAC protocol implementation method and device for adjusting a work cycle based on an energy state. Background technique [0002] In recent years, wireless sensor networks have been widely used in various scenarios, such as health management, industrial measurement, and agricultural monitoring. The scale of sensor networks under these applications is very large, and the traditional battery-powered wireless sensor network cannot meet the demand due to its limited life cycle. Therefore, energy harvesting wireless sensor network (EH-WSN) has received extensive attention. Energy-harvesting sensors can absorb energy from the external environment (solar energy, wind energy, electromagnetic energy, etc.), so their life cycle can ideally be infinitely long. However, because most of the energy in the external environment changes dynamically and intermittently in ...
