AMI network anti-interference attack routing algorithm for advanced measurement system of smart power grid

Abstract

The invention discloses an AMI network anti-interference attack routing algorithm for an advanced measurement system of a smart power grid. The algorithm is an improvement of an RPL routing algorithm,a default RPL path with the optimal performance index can be optimally selected, multiple standby paths can be selected at the same time, and the probability that the standby paths and the default path fail at the same time under the condition that interference attacks exist can be minimum. According to the method, after a default mother node is selected, a penalty term is added to a Rank value of each potential mother node according to an availability history vector, and then a node with the Rank value still smaller than that of the node is selected as a standby mother node. And when the default mother node is unavailable due to Jamming attack, the node can be quickly switched to the standby mother node. When a downlink routing path is formed, DAO information of a node is sent to all mother nodes, so that Root nodes can collect downlink potential routing paths as much as possible, and then a default path and an alternative path reaching a certain downlink node are selected accordingto the provided path availability historical vector.

technical field [0001] The invention belongs to the field of AMI routing algorithms for smart grid advanced measurement systems, and relates to an anti-jamming attack smart grid wireless network routing algorithm, in particular to a smart grid advanced measurement system AMI network anti-interference attack routing algorithm. Background technique [0002] Smart grid advanced measurement system AMI uses wireless communication to establish a communication network for smart meters. How to design a reasonable routing algorithm for smart meters has become a research hotspot. IETF (Internet Engineering Task Force) established the ROLL (Routing Over Low-power and Lossy networks working group) and designed a standard protocol RPL (IPv6 Routing Protocol for Low-power and Lossy networks) suitable for low-power and lossy networks .This protocol is widely considered to be applicable to the smart grid AMI communication network, and a large amount of related research work is in progress. ...

Problems solved by technology

However, there are a series of unresolved problems in the RPL protocol. For example, the routing path in RPL is dominated by a default path. When a fault occurs, the process of rediscovering a new route is very time-consuming, and when there is an interference attack in the AMI network, the RPL The efficiency of routing protocols will be greatly reduced

[0003] In the traditional RPL routing algorithm, a default path plays a major role in the routing path. When a fault occurs, the process of rediscovering a new route is very time-consuming, and when there is interference attack in the AMI network, the efficiency of the RPL routing protocol will be greatly reduced.
