MODIFIED DIJKSTRA'S ALGORITHM WITH CROSS-LAYER QOS
Andrei Bogdan Rus, Virgil Dobrota Adrian Vedinas, Georgeta Boanea Melinda Barabas · 2010
This paper presents a modified Dijkstra's algorithm that calculates the distance between multiple sources and a single destination. It corrects the deficiencies of the classical approach by taking into account the dynamicity of the QoS parameters at the Physical Layer and MAC Sub-layer. The proposed composite metric is based on the available transfer rate, one-way delay and bit error rate, all of them measured or calculated in real time due to a Cross-Layer QoS software module. The proof-of-concept was obtained by simulations in OMNET++.
