Car-following is the most common driving scenario where a following vehicle follows lead in same lane. One crucial factor of car-following behavior style which affects speed and gap selection, acceleration pattern, fuel consumption. However, existing research used limited categories through pre-defined patterns failed to encode into data-driven models. To address these limitations, we propose Aggressiveness Informed Car-Following (AICF) modeling approach, embeds as dynamic input feature In...
Pure all-optical packet-switched networks in which both header processing and packet routing are carried out the optical domain overcome bandwidth bottlenecks of optoelectronic conversions therefore expected to meet needs next generation high speed networks. Due limited capabilities available logic devices, realizations pure near future will likely employ schemes that minimize complexity control. In this paper, we propose a novel self-routing scheme identifies output ports nodes network...
A deflection routing scheme for small to medium size future all-optical networks with arbitrary topologies is proposed. The proposed assumes only single-bit processing and no buffers. primary output selection the alternate choices by a packet at each node are encoded in header order reduce signal requirement. Additional features such as priority time-to-live fields have also been defined. performance of studied using AT&T North America OC-48 optical fiber network topology.
A deflection routing algorithm that can be applied to a novel self-routing address scheme for networks with arbitrary topology is proposed. The proposed implemented all-optically using bitwise optical logic gates. Besides the primary output link selection, alternate choices by packet at each node in case of are also encoded header. Priority classes defined scheme. performance studied AT&T North America OC-48 fiber network topology.
Due to limited available photonic devices, optical networks in the near future will likely employ routing schemes that do not require sophisticated processing of packets. In this paper, we propose a novel self-routing scheme for all-optical packet can be applied with arbitrary topology. The proposed requires only single bit and implemented existing technologies.
Two multicast protocols are proposed for deflection-routed all-optical packet-switched networks. One scheme sends a deflected packet back to the root node while other it deflection point. Both schemes can be implemented using demonstrated optical signal processing technology. The performance of two compared Manhattan street We found that back-to-the-root-node performed better than back-to-the-deflection-node scheme. A hybrid approach further improve system performance.
