An Energy Efficient Threat Free Protocol (ETP) for Data Transmission in Wireless Sensor Networks

Data security and energy efficiency is the most exacting issue in Wireless Sensor Networks (WSNs). In this paper, we propose a protocol for secure and energy efficient data transmission between the source and the destination. This protocol involves Cluster Head Selection (CHS) phase and Secure Data Transmission (SDT) phase. First, CHS phase elects an efficient aggregator node based on localization, then the sensed data is forwarded to the Cluster Head (CH) and CH aggregates data. In turn, SDT phase focused on providing security to aggregated data. Thus, the proposed protocol, ETP utilizes the node’s resource parameter uniformly, which in turn improves Network Lifetime and maximizes Throughput Rate. The ETP is simulated using the NS2 simulator and compared with Fuzzy C-Means centroid algorithm and a secure aggregation protocol implemented using SAR(Secure Aware Ad hoc Routing Routing). The time complexity of ETP protocol is O(m
