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.

Optimized Dynamic Collision Avoidance Algorithm for USV Path Planning. [PDF]
Sensors (Basel), 2023 Ship collision avoidance is a complex process that is influenced by numerous factors. In this study, we propose a novel method called the Optimal Collision Avoidance Point (OCAP) for unmanned surface vehicles (USVs) to determine when to take appropriate ...

Orbital debris–debris collision avoidance [PDF]
Advances in Space Research, 2011 We focus on preventing collisions between debris and debris, for which there is no current, effective mitigation strategy. We investigate the feasibility of using a medium-powered (5 kW) ground-based laser combined with a ground-based telescope to prevent collisions between debris objects in low-Earth orbit (LEO).
