We propose a trust-based decision framework for wireless sensor networks coupled with a non-deterministic routing protocol. Both provide a mechanism to effectively detect and confine common attacks, and, unlike previous approaches, allow bad reputation feedback to the network. This approach has been extensively simulated, obtaining good results, even for unrealistically complex attack scenarios.<\/jats:p>","DOI":"10.3390\/s90503958","type":"journal-article","created":{"date-parts":[[2009,5,25]],"date-time":"2009-05-25T12:11:43Z","timestamp":1243253503000},"page":"3958-3980","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Using Reputation Systems and Non-Deterministic Routing to Secure Wireless Sensor Networks"],"prefix":"10.3390","volume":"9","author":[{"given":"Jos\u00e9 M.","family":"Moya","sequence":"first","affiliation":[{"name":"Dpto.
