Realization method for mobile handover of next generation of IP full wireless sensor network

Abstract

The invention discloses a realization method for mobile handover of a next generation of IP full wireless sensor network. The wireless sensor network comprises a gateway node, a fixed sensor node, a mobile sensor node and a correlative node of the mobile sensor node. The current correlative node of the mobile sensor node is used for carrying out mobile monitoring to the mobile sensor node; and when the mobile sensor node is about to being separated from a communication scope of the mobile sensor node, the correlative node is responsible for searching a next correlative node of the mobile sensor node and executing the mobile handover to ensure the accuracy and the continuity of the mobile sensor node during the communication. In the invention, the mobile handover control information is automatically routed through a network topology, so that the power consumption and the delay time brought by routing are saved. In addition, the mobile sensor node is not required to carry out care-of address and participate in the mobile handover control process, so that the energy is saved, and the service life is prolonged. The invention can be applied to various fields like agricultural facility modernization, medical heat care and the like.

Description

technical field [0001] The invention relates to a system for realizing mobile handover, in particular to a method for realizing mobile handover of a next-generation all-IP wireless sensor network. Background technique [0002] With the wide application of Wireless Sensor Network (WSN) and the development of next-generation Internet, the realization of all-IP communication interconnection between WSN and next-generation Internet has become an inevitable trend of future development. At present, the IETF (Internet Engineering Task Force) working group is working on the research of all-IP communication between WSN and next-generation Internet, and proposed the basic framework of next-generation all-IP wireless sensor network. [0003] With the continuous growth of users' demand for mobile services, the next-generation all-IP wireless sensor network can only obtain greater application space if it provides good mobility support. At present, there are still some problems in the ap...

AI Technical Summary

Problems solved by technology

[0004] 1) In the existing mobile protocol, mobile sensor nodes need to send and receive a large amount of control information to ensure smooth communication during the mobile process and reduce the loss of data packets, and the transmission of control information will consume a lot of energy, which will greatly reduce the sensor the lifetime of the node;

[0005] 2) Existing mobile protocols are implemented based on the network layer, that is, each control information packet needs to include an IPv6 header, which will cause a lot of overhead for sensor nodes with limited resources, and will also shorten the life of sensor nodes
