In this paper, we study the location routing problem with replenishment facilities (LRPRF), an extension of the location routing problem (LRP) where the vehicles can replenish at some replenishment facilities. Vehicles leave the depot with load on-board, serve customers until out of load, and then either return to a replenishment facility to reload or return to the depot, completing their route...

identifying municipal solid waste (msw) disposal sites and appropriately managing them is a challenging task to many developing countries like bangladesh. it is a complex issue in an urban area, as increasing population levels, rapid economic growth and rise in community living standard, accelerates the generation rate of msw. the study area is zone-2 (mirpur-pallabi) of dhaka north city corpor...

Vehicular ad hoc networks are an emerging technology with an extensive capability in various applications including vehicles safety, traffic management and intelligent transportation systems. Considering the high mobility of vehicles and their inhomogeneous distributions, designing an efficient routing protocol seems necessary. Given the fact that a road is crowded at some sections and is not c...

heretofore several position-based routing protocols have been developed for mobile ad hoc networks. many of these protocols assume that a location service is available which provides location information on the nodes in the network.our solutions decrease location update without loss of query success rate or throughput and even increase those.simulation results show that our methods are effectiv...

Existing geographic routing algorithms face serious challenges due to location errors, nonplanarity issues and overhead of location service. To solve these issues, we propose Topological Cluster Based Geographic Routing that combines topology-based routing and geographic routing. It is a localized routing scheme where the geographic routing is performed on an overlay network of topological clus...

With the rising interest of expedient, safe, and high-efficient transportation, vehicular ad hoc networks (VANETs) have turned into a critical technology in smart transportation systems. Because of the high mobility of nodes, VANETs are vulnerable to security attacks. In this paper, we propose a novel framework of software-defined VANETs with trust management. Specifically, we separate the forw...

Manufacturers, who re-supply a large number of customers, continually struggle with the question of how to formulate a replenishment strategy. The purpose of this paper is to determine the optimal set of routes for a group of vehicles in the transportation network under defined constraints – which is known as the Vehicle Routing Problem (VRP) – delivering new items, and resolving the invent...

Transportation planning requires both, decisions on the choice of transport resources and decisions on the deployment of the chosen resources. Therefore, transportation orders must be assigned to resources for fulfillment while the operations for the usage of each resource have to be planned. Most freight forwarding companies have to cope with a strongly fluctuating demand on the transportation...
