In this paper, we present new results on the second-round SHA-3 candidate ECHO. We describe a method to construct a collision in the compression function of ECHO-256 reduced to fou...
—We propose two new protocols based on physical layer network coding for collision resolution in multiple access networks. When a collision occurs the receiver decodes the sum of...
—In this paper, we introduce a collision model for vehicular cluster and we propose path selection algorithms for multi-hop VANETs. That is, we propose the intuitive algorithm na...
We present a velocity-based model for realistic collision avoidance among virtual characters. Our approach is elaborated from experimental data and is based on the simple hypothesi...
Abstract—Packet collision causes packet loss and wastes resources in wireless networks. It becomes even worse in dense WSNs, due to burst-traffic and congestion around sinks. In...
Abstract— We present an algorithm for collision-free navigation of multiple flying robots in three-dimensional workspace. Our approach extends the model of a simple car to a sim...
We describe simple one-dimensional models of passive (no energy input, no control), generally dissipative, vertical hopping and oneball juggling. The central observation is that i...

Abstract: Hash functions are used in many cryptographic constructions under various assumptions, and the practical impact of collision attacks is often unclear. In this paper, we s...
A numerical scheme for bubble trajectories including their collisions is developed. An Eulerian-Lagrangian computational scheme is used to study the bubble trajectories. The 2D ave...
Collisions in overlapping channels are becoming an increasingly important problem in the deployment of high-speed wireless networks. In this paper, we present Remap, a simple, nov...
