However, it is faced with the limitation of energy resources and the transmission bottleneck of sensors in WSN. In this paper, a Model-Based Adaptive Iterative Hard Thresholding (MAIHT) compressive sensing scheme is developed, where a large number of inexpensive sensors are used to collect fine-grained, real-time volcano-seismic signals while a small number of powerful coordinator nodes process and pick arrival times of primary waves (i.e., P-phases). The paper contribution is two-fold. Firstly, a sparse measurement matrix with theoretical analysis of its restricted isometry property (RIP) is designed to simplify the acquisition process, thereby reducing required storage space and computational demands in sensors. Secondly, a compressive sensing reconstruction algorithm with theoretical analysis of its error bound is presented. Experimental results based on real volcano-seismic data collected from a volcano show that our method can recover the original seismic signal and achieve accurate P-phase picking based on the reconstructed seismic signal. <\/jats:p>","DOI":"10.1155\/2015\/769246","type":"journal-article","created":{"date-parts":[[2015,7,13]],"date-time":"2015-07-13T21:07:02Z","timestamp":1436821622000},"page":"769246","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Model-Based Adaptive Iterative Hard Thresholding Compressive Sensing in Sensor Network for Volcanic Earthquake Detection"],"prefix":"10.1177","volume":"11","author":[{"given":"Guojin","family":"Liu","sequence":"first","affiliation":[{"name":"College of Communication Engineering, Chongqing University, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Chongqing University, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuyuan","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Chongqing University, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhenzhi","family":"Yin","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Chongqing University, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bin","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Communication Engineering, Chongqing University, Chongqing 400030, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,7,13]]},"reference":[{"key":"B1-2015-769246","doi-asserted-by":"publisher","DOI":"10.1109\/ewsn.2005.1462003"},{"first-page":"381","volume-title":"Proceedings of the 7th USENIX Symposium on Operating Systems Design and Implementation (OSDI \u203206)","author":"Werner-Allen G.","key":"B2-2015-769246"},{"key":"B3-2015-769246","doi-asserted-by":"publisher","DOI":"10.1145\/1555816.1555847"},{"key":"B4-2015-769246","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2007.4286571"},{"issue":"3","key":"B5-2015-769246","doi-asserted-by":"crossref","first-page":"533","DOI":"10.1016\/j.sigpro.2005.05.027","volume":"86","author":"Donoho D.
