The optimization approach accounts for such factors as the Medium Access Control (MAC) protocol being used, the wireless channel's propagation characteristics, a randomized sleep\/wake-up scheduling protocol, network coverage constraints, the energy consumed, the time to reach a decision, and the number of nodes in the network. The node density that minimizes the average Decision Error Probability (DEP) when a node at the center of the network serves as the Cluster Head (CH) is shown to be a function of the distance from this CH. The solution of this optimization problem and simulations demonstrate both the significant performance improvement provided by nonuniform spatial densities and the trade-offs that are possible amongst energy, network lifetime, detection performance, and time to reach a decision.<\/jats:p>","DOI":"10.1145\/2530288","type":"journal-article","created":{"date-parts":[[2014,1,28]],"date-time":"2014-01-28T13:49:22Z","timestamp":1390916962000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Optimal nonuniform deployment of sensors for distributed detection in wireless sensor networks"],"prefix":"10.1145","volume":"10","author":[{"given":"Vibhav","family":"Kapnadak","sequence":"first","affiliation":[{"name":"Purdue University"}]},{"given":"Edward J.","family":"Coyle","sequence":"additional","affiliation":[{"name":"Georgia Institute of Technology, Atlanta, GA"}]}],"member":"320","published-online":{"date-parts":[[2014,1,31]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2008.928514"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/SURV.2010.020510.00058"},{"volume-title":"Proceedings of the IEEE International Conference on Computer Communications.","author":"Balister P.","key":"e_1_2_1_3_1"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1389-1286(03)00320-7"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TNET.2005.860111"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2009.2036068"},{"volume-title":"Proceedings of the IEEE Military Conference on Communication.","author":"Chen Y.","key":"e_1_2_1_7_1"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2007.70784"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1145\/570738.570745"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2006.1632658"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1145\/1464420.1464425"},{"key":"e_1_2_1_12_1","first-page":"1","article-title":"A survey on mobility and mobility-aware mac protocols in wireless sensor networks","volume":"99","author":"Dong Q.","year":"2012","journal-title":"IEEE Comm.
