This study addresses the challenges of virtualizing a commercial off-the-shelf 4G mobileWiMAX basestation. We highlight additions and modifications needed in theWiMAX network architecture for supporting multiple simultaneous virtual basestations on a single physical basestation. The most prominent features provided by the proposed virtual basestation framework include the capability to perform all frame switching at layer-2, and control mechanisms to provide isolation across slices needed to ensure experiment repeatability. By prototyping on a commercial WiMAX radio, this paper shows the usage of the virtual basestation system for housing mobile virtual network operators and testbeds alike. A use case is shown where the virtual basestation design is used to evaluate mobile handoff schemes. Another usage case is shown for optimizing a video delivery on the edge. The video delivery use case is used to show performance improvements of up to 5dB in the PSNR. Evaluation of prototype shows a significant improvement in the slice isolation, with aggregate throughput improvements of up to 192% achievable through fair resource allocation.<\/jats:p>","DOI":"10.1145\/2169077.2169082","type":"journal-article","created":{"date-parts":[[2012,4,3]],"date-time":"2012-04-03T14:56:22Z","timestamp":1333464982000},"page":"26-37","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["A virtualization architecture for mobile WiMAX networks"],"prefix":"10.1145","volume":"15","author":[{"given":"Gautam","family":"Bhanage","sequence":"first","affiliation":[{"name":"WINLAB, Department of Electrical and Computer Engineering, Rutgers University, NJ"}]},{"given":"Ivan","family":"Seskar","sequence":"additional","affiliation":[{"name":"WINLAB, Department of Electrical and Computer Engineering, Rutgers University, NJ"}]},{"given":"Dipankar","family":"Raychaudhuri","sequence":"additional","affiliation":[{"name":"WINLAB, Department of Electrical and Computer Engineering, Rutgers University, NJ"}]}],"member":"320","published-online":{"date-parts":[[2012,3,27]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"\"Wifi usage and market penetration on wikipedia \" http:\/\/en.wikipedia.org\/wiki\/Wi-Fi.  \"Wifi usage and market penetration on wikipedia \" http:\/\/en.wikipedia.org\/wiki\/Wi-Fi."},{"key":"e_1_2_1_2_1","unstructured":"\"Projected number of mobile users news report \" http:\/\/news.softpedia.com\/news\/5-9-Billion-Mobile-Subscribers-by-2013-126085.shtml.  \"Projected number of mobile users news report \" http:\/\/news.softpedia.com\/news\/5-9-Billion-Mobile-Subscribers-by-2013-126085.shtml."},{"key":"e_1_2_1_3_1","unstructured":"\"World population using mobile phones news report \" http:\/\/www.websiteoptimization.com\/bw\/1002\/.  \"World population using mobile phones news report \" http:\/\/www.websiteoptimization.com\/bw\/1002\/."},{"key":"e_1_2_1_4_1","unstructured":"\"GENI \" http : \/\/www.geni.net\/.  \"GENI \" http : \/\/www.geni.net\/."},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/1851399.1851401"},{"key":"e_1_2_1_6_1","first-page":"5","article-title":"VNTS: a virtual network traffic shaper for air time fairness in 802:16e slices,\" in IEEE ICC - Wireless and Mobile Networking Symposium","author":"Bhanage G.","year":"2010","unstructured":"G.
