Due to many damages that human activities have imposed on the environment, authorities, manufacturers, and industry owners have taken into account the development of supply chain more than ever. One of the most influential and essential human activities in the supply chain are transportation which green vehicles such as electric vehicles (EVs) are expected to generate higher economic and enviro...

System Area Networks (SANs), which usually accept irregular topologies, have been used to connect nodes in PC/WS clusters or high-performance storage systems. Although routing algorithms for SANs usually find out alternative paths, SANs usually accept only deterministic routings. Thus, path selection algorithm, which chooses a single path from alternative paths, becomes essential for advanced r...

A routing protocol chooses one of the several paths (routes) from a source node to a destination node in the computer network, to send a packet of information. In this paper, we propose a new routing protocol, which we call st-routing protocol, based on st-numbering of a graph. The protocol fits well in noisy environments where robustness of routing using alternative paths is a major issue. The...

Shortest path computation is a fundamental problem in road networks with various applications in research and industry. However, returning only the shortest path is often not satisfying. Users might also be interested in alternative paths that are slightly longer but have other desired properties, e.g., less frequent traffic congestion. In this paper, we study alternative routing and, in partic...
