Low power consumption wireless personal area network tree-like routing method based on IPv6

Abstract

The invention belongs to the field of wireless sensor networks, and particularly relates to a low power consumption wireless personal area network tree-like routing method based on IPv6. The method is divided into a node networking stage, a data transmission stage and a path repair stage during operation. The method uses the optimal parent node selection mechanism based on load balancing and an adaptive path prognosis repair mechanism. By reducing the redundancy of a control message and increasing the selected parameters in the parent node selection process, the problems of unreasonable selection, redundancy expenditure in the control message and the like of the existing low power consumption wireless personal area network tree-like routing method based on IPv6 are solved. During a path repair process, the relationship between a failure node and the previous hop node is determined, and then path repair is carried out in a targeted manner. Downlink path repair, the repair of the failure node and other descendant nodes in an uplink transmission process and the like of the existing low power consumption wireless personal area network tree-like routing method based on IPv6 are realized. The node survival rate is improved. The network survival time, the data transmission success rate and other performances are improved.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, in particular to an IPv6-based low-power wireless personal area network tree routing method. Background technique [0002] Since the development of wireless network technology, it has become an indispensable means of communication in people's daily life. From the simple and easy-to-use pager in the past to the increasingly powerful mobile phone, they are all representative products of wireless communication technology. With the increasing demand for communication between people and machines, between machines and machines, in order to meet the requirements of emerging applications in terms of cost, power consumption, and flexibility, wireless sensor networks have emerged as the times require. Wireless Sensor Network (WSN) is an ad hoc network system composed of a large number of small sensor nodes with low power consumption and wireless communication. Its physical layer and data ...
