Secure and Trustable Hierarchical Routing for Large Scale Wireless Sensor Networks

Secure data transmission and energy efficiency is one of the most prominent issues for wireless sensor networks (WSNs). In this paper, we present a secure and trustable hierarchical routing (STHR) scheme based on active detection model for large scale WSNs. The main objective of this paper is that it evaluates the nodal trust very quickly and avoids black holes through number of active detection routes. The energy in non-hotspot is fully utilized by the detection routes to achieve secure data transmission and energy efficiency in the cluster based WSNs. Because the cluster head plays an important role, we propose a priority based cluster head selection algorithm in which an appropriate cluster head is selected based on the highest trust and energy. This scheme also prevents the cluster head to become a compromised node. The analysis shows that our approach improves data route success probability by avoiding potential attack and also optimize network lifetime when compared to traditional methods.
