In this paper, you are required to secure Hotspot throughput analysis in Shopez Mall. You should determine the throughput vs range in meters and repeat the above study for APs using a shared secure key and for the same two packet sizes and compare the results with the corresponding results obtained for open access authentication system.
You are employed as a Wireless Network Engineer by a leading shopping mall company called ShopEz to provide WLAN coverage for the planned hotspots inside the mall. You have the option to provide the hotspots in the mall by using only either the 802.11b or 802.11g WLAN Access Points (APs). Some of the hotspots are to provide Open access authentication while others need to provide shared key authentication to customers who pay a fee.
ShopEz mall wants to provide hotspot access from each of the APs with a minimum throughput of 1
Mbps in its coverage area. This minimum throughput would also be sufficient for the shoppers to
gain access to multimedia services locally as well as over the Internet.
An important question that you need to study experimentally is to determine the variation in the average throughput experienced by the client device(s) vs distance in meters from the AP. In order, to get a good estimate of the throughput at different distances from the AP you need to measure the throughput in four different directions i.e. with client devices antenna directly in Line of Sight of the AP, the client devices antenna at 90 degrees (deg.) from AP, at 180 deg. from AP and at 270 deg. from the AP. The throughput needs to be measured for two different packet sizes i.e. 500 bytes and
As this is an indoor environment so the RF propagation characteristics also come into play. So, a proper choice of either the 802.11b or 802.11g available WLANs also needs to be made along with suitable antennas in the final network.
ShopEz mall is on a tight schedule and budget so you need to quickly create a small testbed using open source tools and software to measure the throughput vs range from AP. You have been told by the IT department of the mall that in the past they have used Iperf tool to emulate the generation of UDP network traffic and Wireshark to sniff the packets.
You should determine the throughput vs range in meters from the AP time for UDP traffic generated first for a packet size of 500 bytes and then 1470 bytes.
You need to repeat the above study for APs using a shared secure key and for the same two packet sizes and compare the results with the corresponding results obtained for open access authentication system. From the comparison of the results an important question that you need to analyse is if the throughput vs range performance is influenced by shared key authentication.
Note: You also need to undertake a serious literature research on tools, security equipment required and any issues that may arise.
You should address the following tasks in your report. You are required to perform detailed literature review on hardware/software, security and other issues.
Group member one:
What in your opinion are the key factors that influence the performance of throughput in the above case study?
Create and discuss the experimental setup for the performance measurement in the above case study with the help of figures.
Create and discuss the Test plan with the help of Figures and tables to evaluate the throughput vs range performance. Provide adequate justifications for each step in the plan.
List the networking, devices and software required including their costs. Group member two:
In your opinion what are the motivations for carrying out the performance study in the above scenario
Research and explain the criteria on which you will select the WLAN in the above scenario i.e.
802.11b or 802.11g.
Prepare the experimental setup of Group member one – Devices, software installations, proper allocation of IP addresses, frequencies and connections and the Testing of connectivity. Creation of UDP traffic type and its details such as packet size, data rates etc.
Methodical measurement of performance and its tabulation for both the open access authentication and shared key case.
Group member three:
Would a mesh network topology be suitable in the above scenario for a peer-to-peer or backhaul communications in the mall? Investigate the implications of using a mesh network.
Discuss the scenario in which the test was conducted such as the height and orientation of devices, antenna types, floor plan with distances, show any obstructions, walls, distances between devices
Document the work of Group members two and one and prepare a complete report in close consultation with members 1 and 2.
Discuss also in the report in the following sections: executive summary, introduction, research/investigation related questions of Group members 1 and 2, research regarding mesh networks suitability and its implications in the above scenario, test and measurements (work of group members 1 and 2), major outcomes from the interpretation of the results, issues and any future tasks.
