Wireless Mesh Network (WMN) provides a cheaper option for backhauls that can be leveraged to provide low-cost access services. Compared to conventional wireless LANs, the benefits of a WMN include greater range because of packet relaying and higher throughput because of shorter hops. A WMN, however, may be subject to a variety of faults that are hard to diagnose manually. In this paper we discu...

This paper deals with a practical transportation model known as the Vehicle Routing Problem with Backhauls (VRPB), which aims at designing the minimum cost route set for satisfying both delivery and pick-up demands. In methodological terms, we propose a local search metaheuristic which explores rich solution neighborhoods composed of exchanges of variable-length customer sequences. To efficient...

This paper investigates moving networks of Unmanned Aerial Vehicles to extend connectivity and guarantee data rates in the 5G by analysing possible hovering locations based on limitations such as flight time coverage. The authors provide analytic bounds requirements terms extension for vehicular served fixed Enhanced Mobile BroadBand infrastructure, where both infrastructures are modelled using...

We present a unified heuristic which is able to solve five different variants of the vehicle routing problem: the vehicle routing problem with time windows (VRPTW), the capacitated vehicle routing problem (CVRP), the multi-depot vehicle routing problem (MDVRP), the site-dependent vehicle routing problem (SDVRP) and the open vehicle routing problem (OVRP). All problemvariants are transformed int...

the vehicle routing problem with backhauls (vrpb) as an extension of the classical vehicle routing prob-lem (vrp) attempts to define a set of routes which services both linehaul customers whom product are to be delivered and backhaul customers whom goods need to be collected. a primary objective for the problem usually is minimizing the total distribution cost. most real-life problems have othe...

The forthcoming communication networks for public safety authorities rely on the fifth generation (5G) of mobile networking technologies. Police officers, paramedics, border guards, as well fire and rescue personnel, will connect through commercial operator's access network rapidly deployable tactical bubbles. This transition from closed dedicated infrastructure to hybrid architecture expand th...
