  • Vehicle Routing Problem Analysis

    In this project, Vehicle Routing Problem (VRP) is studied. VRP is an NP-hard combinatorial optimization problem. It appears in a large number of real world situations, such as transportation of people and products, delivery services, garbage collection etc. It can be applied everywhere, for vehicles, trains, plains; that is why Vehicle Routing Problem is of great practical importance in real life. The Vehicle Routing Problems (VRPs) are the ones concerning the distribution of goods between depots and customers. In particular, the solution of VRP calls for the determination of a set of routes, each performed by a single vehicle that starts and ends at its own depot, such that all requirements of the customers are fulfilled, all operational constraints…

  • KSSL Case Study

    Because of the global impact of such attacks, routing security is a critical issue for the whole Internet infrastructure. Attacks on routing protocols can cause legitimate traffic to flow over unsecure paths and create various types of security exposure for higher layer protocols ranging from eavesdropping to denial of service. Several routing protocols are used to exchange network topology and routing table information between routers. Commonly used intra-domain routing protocols are the…

  • Software Defined Networking ( Sdn )

    interface for switches, routers and middle-boxes1 from diverse vendors [2]. According to Sarah Sorensen, the author of the book of “The Sustainable Network”, “SDN tackles the barriers that constrain scale, automation, and agility by decoupling the forwarding layer from the control layer, which provides a central view and control over the network.” The basic idea behind SDN is to decouple forwarding plane from control plane, therefore SDN- capable switches are merely responsible for forwarding…

  • Case Study: Monitoring IP Spoofing

    packet will take. Hence it is this key observation that made the solution possible, that is analyze what can’t be manipulated by the attacker; the route. Now if a system knows about the best path from a given source to any destination and if it also has some information about the global topology, it can easily analyze the route a packet took and immediately decide if it really originated from the address that it claims to be. If a packet is genuine, it must have followed the best path but if the…

  • Reflective Essay: Nonverbal Routing

    She was focused and direct. The most memorable answer was to eyelash: “Ohhh… the hairs above your eye…I am pretty sure they are hairs.” It was priceless to see her face when I said “eyelash.” On “credible” she commented we just learned this. She gave examples, but did not know a concrete definition. This section is a little harder for me to grade. The subjectivity of the answers causes me to pause and question my score. Based upon her non-verbal routing score she needed to begin on the Nonverbal…

  • Classical Vehicle Routing Case Study

    The PVRP develops the classical Vehicle Routing Problem (VRP) to a planning horizon of several days. Each customer requires a certain number of visits within this time horizon while there is some flexibility on the exact days of the visits. The PVRP is a problem which occurs in companies that have to accomplish periodic repair and maintenance activities or that collect/deliver goods periodically. ¬Early formulations of the PVRP were developed by Beltrami and Bodin (1974) [13]. Christofides and…

  • Dark Net Research Papers

    The dark net and all its secret Drugs, human trafficking, and cyberwarfare, these are the thing that can be found on the dark net. The dark net gives us access to all of the content that is not available to us through the normal means. It was developed in the 1990s by the U.S Navy, it is an encrypted web search that allows anyone to search anything in the comfort of their own home without the fear of being found by the authorities. The dark net has many search engines that is well protected,…

  • Routing And Wavelength Assignment Problem (RWA)

    Design Analysis A connection is recognized in the optical layer regulates to carry the information among the clients in the network. The optical connection is preserved between a source node, s and destination node, d is known as an light path. The problem in finding a route for a light path with wavelength assigned to the light path is submitted as the routing and wavelength assignment problem (RWA). The problem of RWA is divided into two parts : Routing and Wavelength Assignment. In the…

  • Capacitated Vehicle Routing Problem Case Study

    1.1.1 The constituent elements of capacitated vehicle routing problem All kinds of the vehicle routing problem contain a series of essential elements, which primarily are depot, customers, goods, vehicles, routes and the constraints and objective functions proposed to resolve the problem. 1. Depot. Depot is usually the beginning point and terminal of every delivery route. In a specific vehicle routing problem, the number of depot can be one or more than one. The location of the depot can be…

  • The Travelling Salesman Problem: Vehicle Routing Problem

    One of the key functions in logistics systems is physical distribution, involving the flow of products from manufacturing plants or central depots through the transportation network to consumers. It is an expensive function, especially for the industries involving distribution. The Operational Research literature has addressed this problem by calling it as the vehicle routing problem (VRP). Vehicle scheduling or vehicle routing problem (VRP) is a combinatorial optimization and integer…
