Faculty of Computing Engineering & Sciences COCS50721 Mobile Computing and Wireless ASSIGNMENT 2016 / 2017 Dr Alison Griffiths [email protected] Weighting 100 % Deadlines You will be able to submit draft reports approximately 1 month before the deadline and receive initial feedback on your report structure and theory sections, this will not include simulation results. The Deadlines are 2359hrs on the following dates: # Title Optional DRAFT Submission FINAL Submission 1 QoS in Wired and Wireless Packet Switched Networks 2/06/2017 13/06/2017 2 WLAN versus Cellular Access 05/07/2017 21/07/2017 3 WPAN using ZIGBEE technology 05/08/2017 20/08/2017 4 Presentation of any of above N/A 20/08/2017Instructions Assessment for this module will consist of 100% Coursework, with online submission. You will produce three short reports on QoS, WLAN vs Cellular and WPAN using ZIGBEE and present your theory and analyse your simulation results. You are required to submit each report and QUALNET file in a zipped folder in each instance. You will chose your best report and produce a 10min recorded presentation, you will submit the slides and the video of the presentation online by a specified date. Written Report Contents Each report should include the following sections: Abstract Introduction Theory Simulation Configuration Results and Analysis Conclusions. The reports produced should be in the third person and your theory section should be supported by suitable references, cited in an applicable manner (such as the Harvard System, for more information please see http://www.staffs.ac.uk/about_us/university_departments/information_services/learning_sup port/refzone/ To keep within the guidelines of the University for Anonymous marking, within the paper when stating your names, please replace these with your Student ID and email. Remember when writing each report that you will be addressing an intelligent non expert, who is interested in your particular topic. On this basis you do not need to explain every term, only those which you would surmise would be of interest. Submission Requirements You are required to submit an Electronic submission in BlackBoard: • OPTIONAL Draft submission • 3x Submission of FINAL report • 3x zipped copies of QUALNET Project • 3x excel spreadsheet containing results • 1x Submission of a 10 slide power point presentation • 1x Submission of recorded presentationAssessment Criteria Work will be graded according to the criterion-referencing on the following TABLE – read it carefully to avoid losing marks unnecessarily. All students are expected to have read and understood the university's leaflet on plagiarism – any student submitting work which is not their own will be dealt with under the university plagiarism rules. The submission deadlines are shown in DEADLINES section. Try to hand in your assignment earlier than the deadline to avoid problems with queues of people trying to hand in their assignment late. Assessment Criteria for Report Criteria Mark Abstract, Introduction and Conclusion suitable for the paper 7.5 Theory 5 Simulation Results and Analysis 10 Correctly Formatted Report Content written for the correct audience Correct Referencing as per the formatting guidelines 2.5 Assessment Criteria for Oral Presentation Delivery: speed, eye contact, clarity, auditability, tone 5 Content: sets out relevant issues, explains key terms, confident with material, shows understanding 10 Structure: logical, easy to follow, provides headings, each section relates to overall purpose 5 Use of visual aids: uses visual aids relevant to content 5 The following pages contain information specific to each of the three reports.1 QoS in Wired and Wireless Packet Switched Networks You are required to produce a report entitled "QoS in Wired and Wireless Packet Switched Networks" It is your task to determine which of the three different network configurations provides the best QoS under congested conditions. The network configurations are • IP • IP-ATM-IP • IP-MPLS-IP Your report will include a literature survey on Quality of Service, TCP/IP, ATM and MPLS networks. You will then explain your simulation model from which you will collect relevant results and draw suitable conclusions as to which network provides the best QoS for real-time data. A suggested topology for your experiment is shown in Figure 1. Data Server Destination #1 Destination #N Source #N Source #1 IP GATEWAY Wifi Access point Application traffic Voice, Data Traffic IP IP/ATM/MPLS GATEWAY Figure 1: Suggested Topology of Experimental Network Methodology A suggested methodology of this task is as follows: • Create three separate equivalent scenarios: one for IP only, IP-ATM-IP and IP-MPLS-IP • Simulate all IPv4 for VoIP system with SIP signalling and another nonreal time application • Collect results • Add excessive amounts of Background traffic to the network • Re-collect the results and compare the results obtained • Determine the best solution in terms of performance and cost to provide the best QoS.2 Wireless versus Cellular Access to the Fixed Network You are required to produce a report entitled "Wireless versus Cellular Access to the Fixed Network" You will investigate the different access methods to the fixed network including: • 2G Cellular • 3G Cellular • WiMax Your report will include a literature survey on different wireless and cellular access methods including the components required and the technical specifications. You will compare and contrast the different access methods for different real and non-real time applications. You will then explain your simulation model from which you will collect relevant results and draw suitable conclusions. A suggested topology for your experiment is shown in Figure 2. Data Server Destination #1 Destination #N Source #N Source #1 IP GATEWAY Wifi / WiMax Access point Application traffic Voice, Data Traffic IP GATEWAY Choice of fixed Network 2G/3G Cellular Network Data Server Destination #1 Destination #N Figure 2: Suggested Topology of Experimental NetworkMethodology A suggested methodology of this task is as follows: • Create three separate equivalent scenarios: o wired – IP-Core Network –IP-2G o wired – IP-Core Network –IP-3G o wired – IP-Core Network –IP-WIMAX • Create traffic for real-time and non-real-time traffic • Collect results • Compare the performance of each scenario and explain why the results differ by referring to the relevant theory. 3 WPAN Networks using Zigbee Technology You are required to produce a report entitled "WPAN Networks using Zigbee Technology" You will investigate the different technologies suitable to create a WPAN, these will be simulated using QUALNET. Your report should include a literature survey that answers the following questions: What are the different technologies for WPAN Compare and Contrast the different technical specifications of WPANs What are the different topologies of WPANs Give an example application for each of the identified topologies The simulation topology is shown below and the details are shown in the excel spreadsheet found on BlackBoard under assignment submission section.4 Presentation of any of above You will chose one of the previous components to present a 10minute presentation.
