Survey of DoS Attacks on LTE infrastructure used in AMI System and Countermeasures

Smart grid as a cyber-physical infrastructure is vulnerable to a wide variety of attacks. In the smart grid applications, it is essential to investigate attack detection and mitigation methods. AMI is one of the smart grid's applications which collects measurement and event data and sends them to the control centers. Due to the properties of LTE cellular network, it is widely suggested for AMI communication infrastructure. In this paper LTE
¹
network vulnerabilities that lead to Denial of Service to legitimate subscriber have been introduced and the appropriate solutions have been investigated to reduce these attacks or detect them in AMI system.
