Unfortunately such systems can only accommodate 10-20 nodes in an experiment. We have designed and built a prototype of a system that uses software virtualization and live migration to facilitate experiments involving intermittently connected networks with many multiples of the number of physical nodes available on such a testbed.<\/jats:p>\n          <jats:p>Building a system like this presents many technical and research challenges. In this paper, we will describe the physical construction and software architecture of the system while providing a discussion on the research issues that we are currently addressing.<\/jats:p>","DOI":"10.1145\/1925019.1925024","type":"journal-article","created":{"date-parts":[[2011,1,24]],"date-time":"2011-01-24T14:58:13Z","timestamp":1295881093000},"page":"21-25","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":6,"title":["Using virtualization and live migration in a scalable mobile wireless testbed"],"prefix":"10.1145","volume":"38","author":[{"given":"Dongwoon","family":"Hahn","sequence":"first","affiliation":[{"name":"University of Maryland, College Park, MD"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ginnah","family":"Lee","sequence":"additional","affiliation":[{"name":"University of Maryland, College Park, MD"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brenton","family":"Walker","sequence":"additional","affiliation":[{"name":"Laboratory for Telecommunications Sciences, College Park, MD"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matt","family":"Beecher","sequence":"additional","affiliation":[{"name":"Laboratory for Telecommunications Sciences, College Park, MD"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Padma","family":"Mundur","sequence":"additional","affiliation":[{"name":"University of Maryland, College Park, MD"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2011,1,3]]},"reference":[{"unstructured":"\"The Network Simulator NS-2.\" http:\/\/www\/isi.edu\/nsnam\/ns\/.  \"The Network Simulator NS-2.\" http:\/\/www\/isi.edu\/nsnam\/ns\/.","key":"e_1_2_1_1_1"},{"doi-asserted-by":"publisher","key":"e_1_2_1_2_1","DOI":"10.4108\/ICST.SIMUTOOLS2009.5674"},{"key":"e_1_2_1_3_1","first-page":"1","article-title":"Meshtest: Laboratory-based wireless testbed for large topologies","author":"Clancy T.
