Abstract

In recent years, the secure data transmission is a complex issue that has been witnessed in the field of Wireless Sensor Networks (WSNs) such as disaster management, conflict field inspection, border protection and security espionage. Sensors in those applications are expected to deploy remotely in an abandoned environments. To support scalability, nodes are often grouped into disjoint and mostly non-overlapping clumps. In this research, a secured data transmission was analyzed for Clump based Wireless Sensor Networks (CWSNs), where the clumps are formed periodically and dynamically. The Secure and Efficient Data Transmission (SET) protocol is proposed for CWSNs, called SET-IBS and SET-IBOOS by using the Identity based Digital Signature (IBS) scheme and the Identity based Online/Offline Digital Signature (IBOOS) scheme respectively. The simulation result shows that the proposed protocol have better performance over the  traditional secure protocols for CWSNs, in terms of security overhead and energy consumption.
