Abstract

The invention discloses a multi-metric fusion objective function construction method of a routing protocol, which comprises the following steps of: respectively calculating a hop count Rank value of each child node, an expected transmission frequency from the child node to a father node and a storage parameter of the father node by collecting child node routing data and cache information data of a Mac layer, and constructing a multi-metric fusion objective function; a multi-metric fusion model is obtained; calculating the Rank value of each sub-node of the topological structure according to the multi-metric fusion model, and constructing a network topological structure; according to the method, on the basis of the link load problem, multiple metrics are constructed through the cache proportion and the cache growth rate and fused to form the high-reliability routing protocol, under the condition that the basic communication quality and the transmission hop count are guaranteed, link balance under the condition that the load is heavy is achieved, the reliability and robustness of the whole routing protocol are improved, and the service life of the routing protocol is prolonged. And the basic communication quality and the transmission hop count are ensured.

Description

technical field [0001] The invention relates to the field of routing protocols, in particular to a method for constructing a multi-metric fusion objective function of a routing protocol. Background technique [0002] Low Power and Lossy Network (LLN) is a link network composed of a large number of restricted nodes, which is mainly manifested in the limitations of its processing capacity, storage capacity, and energy reserve capacity. In 2012, the IETF organization proposed an IPv6 routing protocol for low-power and lossy networks (IPv6 Routing Protocol for Low-Power and Lossy Network, RPL) for LLN network characteristics. The RPL routing protocol is a distance vector routing protocol. Objective Function (OF) is a crucial part in the RPL routing protocol to establish a destination-oriented directed acyclic graph (Destination Oriented DAG, DODAG) topology. It defines the goals of routing performance, such as low latency, energy saving, and high reliability. The objective fu...
