There is a requirement for a basic network security element included within the report. Individual Assessment: Individual assessment. The report phase of the work you submit shall be your own and not the product of collaboration with anyone else. Plagiarism will be penalised. IMPORTANT STATEMENT Plagiarism: the presentation of the work of another (from whatever source: book, journal, internet etc) as if it were one's own independent work. This can be anywhere on a continuum ranging from sloppy paraphrasing to verbatim transcription without crediting sources. You are advised to refer to the Student Handbook on matters of cheating and plagiarism as they relate to coursework, group assignments, class tests and examinations. Both cheating and plagiarism are totally unacceptable and the University maintains a strict policy against them. It is YOUR responsibility to be aware of this policy and to act accordingly. The University requires that the following statement is included in all module documents. "You are reminded of the University Disciplinary Procedures which refer to cheating. Except where the assessment of an assignment is group-based, the final piece of work which is submitted must be your own work. Close similarity between assignments is likely to lead to an investigation for cheating. It is not advisable to show your completed work to your colleagues or to share and exchange disks. You must also ensure that you acknowledge all sources you have used. Work which is discovered to be the result of collusion or plagiarism will be dealt with under the University's Disciplinary Procedures, and the penalty may involve the loss of academic credits. If you have any doubts about the extent to which you are allowed to collaborate with your colleagues, or the conventions for acknowledging the source you have used, you should first of all consult module documentation and, if still unclear, your module tutor." You will be asked to confirm in writing when handing in any piece of assessed work that it is your own by completing the Coursework Submission & Record Form which should be printed from ECMS My-course on https://mytid.bcu.ac.uk/. It is the STUDENT'S responsibility to accurately complete the form and comply with its rules and guidance as described in the student handbook for this academic year.

Assignment Details: Title: Wireless Call Centre Network Design Report Introduction You are required to write a report to the directors of a newly formed SME call centre company known as CompanyXYZ. Their priority is to implement customer service over the internet initially capable of securely handling services over both voice and data communications. All outside communications initially are channelled into a central call manager and then relayed to an operator. If the operator cannot deal with the request an enquiry is made to the wireless warehouse (Basic Signalling set BSS) via voice or data communications. The initial topology is shown in figure 1 below. Fig 1 Task A Discuss how a Wireless Call centre can be set up to communicate with the network outside world, utilising routing protocol and wireless technologies. Task B What are the issues with setting up a converge network transporting UDP and TCP traffic over a wireless network .How does the Cisco Call Manager help overcome any pre-mentioned issues Part C The warehouse will at times need to communicate with a remote site which is wireless based, to provide essential supplies forming an Extend Signalling Set (ESS). What is the difference between a BSS and an ESS, discuss in terms of figure 2 Fig 2 Part D To ensure that the wireless is effective within the warehouse environment you must discuss the problems of the RF carrier waves to pass through certain environments. The main environmental issues for a small warehouse are glass metal walls and floor, and stairwells. There is also the issue of wireless communication distance in terms of free space dissipation. These issues should be described and discussed within the report along within an analysis of the most appropriate wireless standard to be used. You are also required to discuss an appropriate 802.11 standard to ensure the most suitable WLAN environment for CompanyXYZ. Part D The company is also concerned with wireless security, the wireless network is currently using WEP for its network security, as a security analyst you have to show the weakness of WEP is exposed by showing the WEP key to the customer. The SSID is being broadcast (Widget W). Within the port state the weaknesses of WEP and state the WEP key that they have been using, also recommending a stronger security protocol for the wireless network. Finally you must ensure your report contains a short introduction and concise conclusion and must be of approximately 3000 words Information can gained from the course work and associated Labs. Also information can be gained from Cisco.com or any CCNA/CCNP Assessment Table of Assessment Criteria and Associated Grading Criteria Assessment Criteria  1. Voice wireless configuration 2.

The required development environment: Using the Visual Studio Development Environment of your choice (worth 100% of the total marks for the assignment), Coursework: 3D Rendering of any Two Shapes This section describes the main aim of this coursework task. Before you start this task, make sure you have read and understood the sections on the environment and data formats at the end of this document. This coursework exercise is a practical programming exercise which should be done using OpenGL. Robust reflections use stenciling. Robust projected shadows use both stenciling and polygon offset. I insist that you do not collaborate with anyone on this piece of work. You may discuss high level issues as laid down in the computer science assessed work guidelines. Try to keep your code and the use methods as tidy, do not tell anyone about your Innovation and novelty in the animation. Write a 300 words self-reflective commentary about the design and development experiences you had while undertaking the assignment, and what you learned about your own work practices as a result. The required development environment: Using the Visual Studio Development Environment of your choice. You can program either in C or C++. The goal of the coursework is to develop 3D rendering of any Two Shapes, to show how to combine texturing, lighting, rotation and projected shadows all in real-time with OpenGL. You should write a program that displays a virtual world with 3D object (any two shapes). Successfully rendered object will have the following characteristics: • Looks realistic. Objects could be colored, textured, show varied light sources, and object should be relevant to the scene; • Has some movement and rotation; • Can be viewed from different positions/angles (viewing/projection); • Allows user controlled viewing (keyboard and mouse inputs) The student should ensure that his/her program runs independently and without error on a machine (particularly if you have used the libraries at home on a PC) and that all required parts (files, including textures) are contained in your submission. The substantial comment must be included at the top of the program which includes your name, course, year and a statement that this is your own work. This comment should also include a description of what your program does (i.e. how to *combine* texturing, reflections, and projected shadows all in real-time with OpenGL). Deliverables You must present the outcomes of coursework in a report format. Additionally, email your programme (not report) to your tutor ([email protected]) as a zip file. However, your score and feedback will be based only on your report. Cover Page: Assignment title, module code, full name and student number as well as submission date. Table of Contents: A list of all of the sections, headings and sub-headings, appendices and figures should be provided as well as all page numbers as clearly as possible. Introduction: This should summarise your response to the task and the strategy you are presenting. Development Log This is the substance of your report. You should take your reader through screen grabs of the functioning program, code snippets and explanations of that code. You should use your experiences to structure your log, clearly demonstrating how you addressed each of the requested tasks and demands.
