The advantages of dual-layer networks are improving network capacity and overcoming the problem of unbalanced traffic distribution in time-space domain. In this paper, performance of small cells deployment is evaluated in simulations. It is shown that users\u2019 traffic is offloaded by small cells obviously. At the same time, performances of signal to interference plus noise ratio (SINR) and throughput are also improved. However, low SINR ([Formula: see text]\u2009dB) users are also increased because of interferences between macro cells and small cells. Furthermore, a new cooperation scheme is proposed for energy saving in dual-layer networks. This scheme is implemented through a functional modular, named by Area Control Center (ACC). Finally, simulations are given to verify the efficiency of this energy saving scheme. The numerical results show that energy consumption could be reduced by 20%. <\/jats:p>","DOI":"10.1155\/2014\/929805","type":"journal-article","created":{"date-parts":[[2014,3,20]],"date-time":"2014-03-20T03:04:02Z","timestamp":1395284642000},"page":"929805","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Small Cell Deployment and Smart Cooperation Scheme in Dual-Layer Wireless Networks"],"prefix":"10.1177","volume":"10","author":[{"given":"Su","family":"Wei","sequence":"first","affiliation":[{"name":"College of Electronics and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Liu","family":"Qi","sequence":"additional","affiliation":[{"name":"Wireless Technology Research Center, Networks Technology Research Institute, China Unicom, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li","family":"Yiqun","sequence":"additional","affiliation":[{"name":"Wireless Technology Research Center, Networks Technology Research Institute, China Unicom, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bi","family":"Meng","sequence":"additional","affiliation":[{"name":"Wireless Technology Research Center, Networks Technology Research Institute, China Unicom, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Guoli","sequence":"additional","affiliation":[{"name":"Wireless Technology Research Center, Networks Technology Research Institute, China Unicom, Beijing 100048, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhang","family":"Hongke","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Beijing Jiaotong University, Beijing 100044, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,3,19]]},"reference":[{"key":"B2-2014-929805","doi-asserted-by":"publisher","DOI":"10.3724\/SP.J.1016.2010.01569"},{"key":"B3-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/WCNC.2012.6214290"},{"key":"B4-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2012.6189405"},{"key":"B5-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/VTCFall.2012.6398953"},{"key":"B6-2014-929805","doi-asserted-by":"publisher","DOI":"10.1364\/NFOEC.2013.NTh3F.2"},{"key":"B7-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2013.6515046"},{"issue":"10","key":"B8-2014-929805","first-page":"1833","volume":"35","author":"Liu Q.","year":"2007","journal-title":"Acta Electronica Sinica"},{"issue":"9","key":"B9-2014-929805","first-page":"2148","volume":"39","author":"Su W.","year":"2011","journal-title":"Acta Electronica Sinica"},{"key":"B10-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/ICTEL.2012.6221210"},{"issue":"3","key":"B11-2014-929805","first-page":"273","volume":"9","author":"Liu Q.","year":"2008","journal-title":"Journal of Internet Technology"},{"key":"B12-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2013.130503"},{"key":"B13-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2011.5978418"},{"key":"B14-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/TWC.2011.120911.111494"},{"key":"B15-2014-929805","doi-asserted-by":"publisher","DOI":"10.1049\/cp:20061270"},{"key":"B16-2014-929805","doi-asserted-by":"publisher","DOI":"10.1109\/GMC.2010.5634553"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2014\/929805","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1155\/2014\/929805","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2014\/929805","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,16]],"date-time":"2021-05-16T16:31:43Z","timestamp":1621182703000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1155\/2014\/929805"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,3,1]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2014,3,1]]}},"alternative-id":["10.1155\/2014\/929805"],"URL":"https:\/\/doi.org\/10.1155\/2014\/929805","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"type":"print","value":"1550-1477"},{"type":"electronic","value":"1550-1477"}],"subject":[],"published":{"date-parts":[[2014,3,1]]}}}
