DEroute: trust-aware data routing protocol based on encryption and fuzzy concept for MANET secure communication in Iot

Abstract

ABSTRACT The Internet of Things in smart environments interrelates with Mobile Ad‐hoc Network and Wireless Sensor Network, which becomes more attractive and efficiently flourishing. Moreover, Mobile Ad‐hoc Network is applied in various fields including intelligent transportation, emergency communications after disaster, and Internet of Things. The incorporation of Internet of Things and Mobile Ad‐hoc Network become a rising theory for enabling opportunistic communication in Internet of Things. The security provisioning for secure communication is still the major challenge in Mobile Ad‐hoc Network – Internet of Things. Thus, in this paper, the DEroute algorithm is developed for secure communication Internet of Things structure, where Internet of Things nodes are located in mobile ad-hoc manner. In order to avoid the route list modification, nodes’ address is encrypted based on generated secret keys by Diffie–Hellman key-exchange algorithm. The fuzzy system with trust parameters, like historical, indirect and direct trust factors are considered for the identification of secure nodes. The bi-filtering process is also performed for filtering important nodes. Thus, the developed DEroute model achieved enhanced performance with respect to delay, packet delivery ratio and throughput of 0.1674 sec, 87.23% and 25.19 mbps, respectively.
