However, wireless nodes may acquire different network information with various users\u2019 location and mobility, channels\u2019 conditions, and other factors, which results in asymmetric information between the source and the relay nodes (RNs). In this paper, the relay incentive mechanism between relay nodes and the source is investigated under the asymmetric information. By modelling multiuser cooperative relay as a labour market, a contract model with moral hazard for relay incentive is proposed. To effectively incentivize the potential RNs to participate in cooperative relay, the optimization problems are formulated to maximize the source\u2019s utility while meeting the feasible conditions under both symmetric and asymmetric information scenarios. Numerical simulation results demonstrate the effectiveness of the proposed contract design scheme for cooperative relay.<\/jats:p>","DOI":"10.1155\/2015\/690807","type":"journal-article","created":{"date-parts":[[2015,10,19]],"date-time":"2015-10-19T17:06:21Z","timestamp":1445274381000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Optimal Contract Design for Cooperative Relay Incentive Mechanism under Moral Hazard"],"prefix":"10.1155","volume":"2015","author":[{"given":"Nan","family":"Zhao","sequence":"first","affiliation":[{"name":"Hubei Collaborative Innovation Center for High-Efficiency Utilization of Solar Energy, Hubei University of Technology, Wuhan 430068, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minghu","family":"Wu","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for High-Efficiency Utilization of Solar Energy, Hubei University of Technology, Wuhan 430068, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Xiong","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for High-Efficiency Utilization of Solar Energy, Hubei University of Technology, Wuhan 430068, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cong","family":"Liu","sequence":"additional","affiliation":[{"name":"Hubei Collaborative Innovation Center for High-Efficiency Utilization of Solar Energy, Hubei University of Technology, Wuhan 430068, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1080\/00207217.2015.1006688"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2004.1341264"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2008.061097"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/mcom.2014.6852082"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2009.12.090684"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/twc.2013.051613.121171"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/tmc.2012.231"},{"year":"2005","key":"8"},{"year":"2005","key":"9"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/jsac.2013.130322"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1109\/tnet.2013.2270954"},{"journal-title":"International Journal of Distributed Sensor Networks","key":"12"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.1040.0229"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1049\/iet-com.2012.0748"},{"year":"2007","key":"15"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/jsac.2011.110415"}],"container-title":["Journal of Electrical and Computer Engineering"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/690807.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/690807.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jece\/2015\/690807.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,7,27]],"date-time":"2016-07-27T17:13:26Z","timestamp":1469639606000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jece\/2015\/690807\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":16,"alternative-id":["690807","690807"],"URL":"https:\/\/doi.org\/10.1155\/2015\/690807","relation":{},"ISSN":["2090-0147","2090-0155"],"issn-type":[{"type":"print","value":"2090-0147"},{"type":"electronic","value":"2090-0155"}],"subject":[],"published":{"date-parts":[[2015]]}}}
