Multi-ship Coordinated Collision Avoidance Decision Based on Improved Twin Delayed Deep Deterministic Policy Gradient [PDF]

Jisuanji kexue, 2023
At present,most models of collision avoidance algorithms take ships as single agent to make collision avoidance decisions,without considering the coordinated avoidance between ships.In the scenario of multi-ship meeting,it will lead to poor avoidance ...

Collision avoidance tree networks [PDF]

Computer Networks and ISDN Systems, 1994
Abstract The Collision Avoidance Tree is a local area network based on a hardware device called the collision avoidance switch. The collision avoidance switch arbitrates random access to a shared communication channel and avoids the penalty of collisions among packets.
