Over the last decade, wireless devices have developed rapidly until predictions will develop with high complexity and dynamic. So that new capabilities are needed for problems in this problem. Software Defined Network (SDN) is generally a wire-based network, but to meet needs of users terms its implementation, it has begun introduce Wireless-based SDN called Wireless (SDWN) which provide...

(ABSTRACT) In this dissertation, we consider two important problems pertaining to the analysis of transportation systems. The first of these is an approach-dependent, time-dependent, label-constrained shortest path problem that arises in the context of the Route Planner Module of the Transportation Analysis Simulation System (TRANSIMS), which has been developed by the Los Alamos National Labora...

All-Pairs Shortest Paths: Earlier, we saw that Dijkstra’s algorithm and the Bellman-Ford algorithm both solved the problem of computing shortest paths in graphs from a single source vertex. Suppose that we want instead to compute shortest paths between all pairs of vertices. We could do this applying either Dijkstra or Bellman-Ford using every vertex as a source, but today we will consider an a...

Dijkstra is a greedy algorithm that gives choice of several available shortest routes and then provides solution. The application Dijkstra's Algorithm in everyday life very diverse. This study collects research results regarding the to solve problems such as path problem, this mini-review paper can explain for various things, including solving bi-objective routes, multi-objective emergency evac...

Shortest path algorithms finds applications in large real world domains. All pair shortest path (APSP) and single source shortest path (SSSP) both have their special applications domains. All though every SSSP can be applied for all vertices to calculate APSP. But APSP cant. In this paper heterogeneous implementation of Floyd warshalls algorithm and Dijkstra’s algorithm is compared on dense gra...

To save the escaping time for the coal mine flood, improve the emergency rescue efficiency, an NShortest Paths algorithm utilized bidirectional search is presented, which is based on the classical Dijkstra algorithm. The algorithm was proposed roadway length equivalent weights to simulate the mine roadway length. Combined with GIS theory to extract topology structure of mine, an undirected weig...

In a number of applications, the problem of determining the optimum path occurs. This applications range from finding the fastest path in a network, to determining the safest path for mobile vehicle, wandering on the surface of Mars. In this context, we shall limit our scope to the case of finding paths in Euclidean two-dimensional space. Moreover we shall limit the case study to movements alon...
