Although our previous star-based system configuration has been in operation for more than 13 years, it does not scale well for sensorization of large buildings or when deploying hundreds of nodes. In this paper we demonstrate the feasibility of a cluster-based dynamic-tree hierarchical Wireless Sensor Network (WSN) architecture where realistic assumptions of radio frequency data transmission are applied to cluster construction, and a mix of heterogeneous nodes are used to minimize economic cost of the whole system and maximize power saving of the leaf nodes. Simulation results show that the specialization of a fraction of the nodes by providing better antennas and some energy harvesting techniques can dramatically extend the life of the entire WSN and reduce the cost of the whole system. A demonstration of the proposed architecture with a new routing protocol and applied to termite pest detection has been implemented on a set of new nodes and should last for about 10 years, but it provides better scalability, reliability and deployment properties.<\/jats:p>","DOI":"10.3390\/s111110074","type":"journal-article","created":{"date-parts":[[2011,10,25]],"date-time":"2011-10-25T12:46:40Z","timestamp":1319546800000},"page":"10074-10093","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Historical Building Monitoring Using an Energy-Efficient Scalable Wireless Sensor Network Architecture"],"prefix":"10.3390","volume":"11","author":[{"given":"Juan V.","family":"Capella","sequence":"first","affiliation":[{"name":"ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5782-4284","authenticated-orcid":false,"given":"Angel","family":"Perles","sequence":"additional","affiliation":[{"name":"ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3639-8420","authenticated-orcid":false,"given":"Alberto","family":"Bonastre","sequence":"additional","affiliation":[{"name":"ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}]},{"given":"Juan J.","family":"Serrano","sequence":"additional","affiliation":[{"name":"ITACA Institute, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46022 Valencia, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2011,10,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6","DOI":"10.1109\/MWC.2004.1368893","article-title":"Routing techniques in wireless sensor networks: A survey","volume":"11","author":"Kamal","year":"2004","journal-title":"IEEE Wirel.
