Editorial note for the special issue on smart transportation.

This paper proposes an algorithm called NiCS to not only detect GNSS signal spoofing but also counter it. The Guest Editors would like to present the sixth paper of the special issue, "Mitigating Spoofed GNSS Trajectories through Nature Inspired Algorithm", authored by Saravjeet Singh, Jaiteg Singh, and Sukhjit Singh. Unlike many other existing algorithms that rely on dedicated hardware, NiCS uses inertial sensors, which are widely available in mobile phones nowadays, making the algorithm easy to deploy.
