Embodiment Construction

[0018] A miniature sensor node is mainly composed of four parts: power supply, sensing unit, processing unit and transceiver unit. In addition to the power supply unit that generates energy, the sensing unit, processing unit and transceiver unit are all energy sources of sensor nodes, and the data transceiver unit is the main part of energy consumption.

[0019] The methods of energy control mainly focus on the dormancy mechanism, data fusion, conflict avoidance and error correction, etc. They are applied to all aspects of the computing module and communication module. The specific analysis is as follows:

[0020] 1) Hardware energy saving

[0021] In hardware selection, low-power components should be used to make a compromise between performance and power consumption to reduce the overall power consumption of the system. The processor should support the adjustment of the operating voltage and operating frequency, so as to provide the necessary conditions for the dormancy of ...

Abstract

The invention discloses an energy saving method for an IPv6 wireless sensor network. Nodes of the wireless sensor network are generally comparatively small which are usually powered by batteries, the number of nodes is very huge and batteries changing is very troublesome. As a result, energy saving is an important part in applications of the wireless sensor network. After analyzing the traditional energy saving methods applied to the wireless sensor network and the energy consumption of each module of the sensor nodes, the invention carries out an energy consumption test on each module relating to a specific node, removes unimportant devices with huge energy consumption, invents a nodes dormancy mechanism and a network synchronized dormancy mechanism, and brings forward a scheduling algorithm for sensor network dormancy and a command frame format for the same. The invention effectively solves the problem of energy saving in the wireless sensor networks.

Description

technical field [0001] The invention relates to an energy-saving scheme for an IPv6 wireless sensor network. Background technique [0002] Wireless sensor network nodes are the most basic components of wireless sensor networks, responsible for information collection, processing and transmission. Wireless sensor nodes are small in size and usually use batteries with limited energy. Since sensor nodes have very limited computing, storage, and communication capabilities, they need to communicate frequently with distant base stations. Network lifetime measured by time - all nodes in the network are depleted of energy or no longer provide effective event detection, directly impacting the effectiveness of the network. Due to the large number of sensor nodes, low cost requirements, wide distribution area, and complex deployment area environment, some areas cannot even be reached by personnel, so it is unrealistic for wireless sensor nodes to supplement energy by replacing batterie...
