Several low earth orbit (LEO) satellite constellations have been proposed for mobile satellite systems (MSS’s). Due to nonstationary coverage regions of individual LEO satellites, the offered traffic load for each cell varies continuously. The variation of the traffic load essentially requires dynamic channel assignment. Furthermore, extremely frequent handover requests require specific techniq...

Abstract– With limited frequency spectrum and a tremendous growth in the demand for mobile communication services, the problem of channel assignment becomes increasingly important. Efficient channel assignment allows for an increased utilization of the limited frequency spectrum available for land mobile radio-telephone service. In this paper, a new traffic-adaptive non-uniform compact pattern ...

How to model traveler’s perception of travel time is always an important issue in the development of traffic assignment models. Since travelers rarely have perfect knowledge of the road network or of the traveling conditions, they choose routes based on their perceived travel times. Traditionally, travelers’ perceived travel times are treated as random variables, leading to the stochastic traff...

This paper proposes a distributed and adaptive channel assignment (D-CAS) scheme for wireless sensor networks. D-CAS performs statistical analysis of load pattern of the individual cluster and adjusts channel assignment dynamically as per requirement generated by the current cluster’ traffic load. It follows a static schedule during infrastructure establishment based on initial traffic conditio...

The number of electric vehicles is increasing rapidly worldwide, leading to demand for charging. This will negatively impact the grid. Therefore, it essential relieve power grid operation pressure by changing charging behaviour users. In this paper, was guided price instruments maintain balance paper uses travel simulation establish relationship between and electricity prices. results were eval...

In transportation modeling, after defining a road network and its origin-destination (OD) matrix, the next important question is how to assign traffic among OD-pairs. Nowadays, advanced traveler information systems (ATIS) make it possible realize user equilibrium solution. Simultaneously, with advent of Cooperative Intelligent Transport Systems (C-ITS), solve assignment problem in system optimu...
