We consider a grid network where nodes contain small buffers. A packet that faces a crowded buffer in its route will get extra latency and may be dropped. In this paper, we propose a novel flow control protocol called RFCC for grid networks. RFCC tries to reroute delayed packets and utilizes network coding to introduce a configurable amount of redundant information in the network, thereby incre...

increasing urban network has both positive (accessibility) and negative (air pollution) impacts. in this research air quality is chosen as key elements with respect to their critical roles in quality of life and urban health. the overall objective of this study is to develop a mathematical model to plan appropriate locations for residential land uses and urban transportation network development...

Originally studied for designing min cost connecting grid (in distribution, transportation, communication applications) to connect a set of cities. Under arc lengths > 0 min cost connecting network will bea spanning tree (ST). Earliest algo. (Boruvka's) dates back to 1926! Undirected, connected G = (N A c). To nd an uncon-strained MCST in G. c arbitrary. Constrained MCST problems (typical const...

the objective of this study was to develop a cost minimizing pattern for cube sugar and sugar transportation from production centers to refinement and storage centers and finally to distribution and consumption  centers in  fars province. producing centers are marvdasht (27.3%), eghlid (27.9%), fasa (11.3%), kavar (7.3%) and mamasani (20.2%). some of the province’s cube sugar and sugar is provi...

this paper examines the effect of the poor road transportation network on crop production in one of the rural agrarian local government of kwara state, nigeria. a well-structured interview schedule was conducted to elicit information from 120 crop farmers using a two-stage sampling technique. findings from the study revealed that the poor road transportation network in their area had led to a r...

With an increasing deployment of plug-in electric vehicles, evaluating and mitigating the impacts of additional electrical loads created by these vehicles on power distribution grids become more important. This paper explores the use of prices of electricity at public charging stations as an instrument, in couple of road pricing, to better manage both power distribution and urban transportation...

In this article we present an algorithm for converting a network problem with several sources and several sinks including several transfer nodes and condition of supplying the demand of any sink from a particular source to the transportation problem.  Towards this end, and considering the very special structure of transportation algorithm, after implementing the shortest path algorithm or ...
