Problems solved by technology

In this way, the sensor node needs the mobile IP protocol for mobility management. Since the MIP protocol stack is a host-based mobility management protocol, the consumption of power and processing power for the sensor node is relatively large; The data packets between communication nodes with the outside world need to go through the tunnel between MR and HA, which is inconvenient for a lightweight sensor node

Abstract

The invention provides a technical scheme of sensor network group mobility management, which comprises steps as follows: when a sensor network node moves, an access network gateway corresponding to the sensor network node determines whether the sensor network group of the node moves, and requires a control device at the network side to carry out position updating on the network gateway corresponding to the sensor node in the sensor network group; and the network gateway carries out local position updating according to the confirmation message of the control device, and updates the addressable information of the sensor node in the sensor network group corresponding to the sensor network as well as the mapping relationship between the addressable information in the access network. The technical scheme implements mobile management on the sensor network group on the basis of the network side, does not need to implement related mobile management signaling on the sensor node, and is applicable to sensor nodes with limited power consumption and capacity.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for managing the mobility of a sensor network group. Background technique [0002] The sensor network is a comprehensive intelligent information system integrating information collection, information processing, and information transmission. It can be used in many fields such as public safety, ecological environmental protection, intelligent transportation, and smart home. For example, the sensor / controller network in the smart home, the collection of various parameters on the industrial site, and the unified network regulation of the controller can all be realized through the sensor network. [0003] When a sensor network moves, it needs to perform location update operations in related network entities. If each sensor node under the sensor network performs location update operations independently, it will cause a large number of mobility management sig...
