In WSN, where nodes, in addition to having their inbuilt capability of sensing, processing, and communicating data, also possess certain risks. These risks expose them to attacks and bring in many security challenges. Many researchers are engaged in developing innovative design paradigms to address security issues by developing trust management systems. In WSN, trust is important for the establishment of cooperation among the sensor nodes. The article presents a sociopsychological model for detecting fraudulent nodes in WSN. The three factors, viz. ability, benevolence, and integrity, are used for the computation of trust. Furthermore, the article provides a novel consensus-aware sociopsychological approach to deal even in the presence of higher number of fraudulent nodes than benevolent nodes. The proposed work has been implemented in the LabVIEW platform and extensive simulations were carried out to study its performance. Additionally, it is experimentally evaluated on a testbed of size 16 nodes to obtain results that demonstrate the accuracy and robustness of the proposed model.<\/jats:p>","DOI":"10.1145\/2903721","type":"journal-article","created":{"date-parts":[[2016,7,26]],"date-time":"2016-07-26T13:27:29Z","timestamp":1469539649000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":23,"title":["Consensus-Aware Sociopsychological Trust Model for Wireless Sensor Networks"],"prefix":"10.1145","volume":"12","author":[{"given":"Heena","family":"Rathore","sequence":"first","affiliation":[{"name":"Indian Institute of Technology Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Venkataramana","family":"Badarla","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Supratim","family":"Shit","sequence":"additional","affiliation":[{"name":"Indian Institute of Technology Jodhpur, Rajasthan, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2016,7,26]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/MWC.2004.1368893"},{"key":"e_1_2_1_2_1","volume-title":"Proc.
