Improved Hybrid LEACH Based Approach for Preserving Secured Integrity in Wireless Sensor Networks

Wireless sensor networks are must important nowadays and with rapid propagation. Also, when the accuracy of data is most importantly in the Internet of Things, detecting sensor data with faulty readings is an important issue of secure communication and power consumption. So, requirement of energy-efficiency and integrity of information is mandatory. Thus, cryptography is an effective technique that provides integrity to sensed data. In contrast, we can’t simply transferred traditional cryptographic techniques to WSNs due to sensors constraints. This paper, deals with the proposition of a novel energy-efficient and data integrity version of LEACH based routing protocol on Watermarking for wireless sensor networks because LEACH routing protocol does not take the security aspect into consideration and the secure improved LEACH works are based only on cryptographic techniques. Our hybrid proposed approach based on the Watermarking-LEACH achieves not only data integrity but also Energy-Efficient. It is the first schema that attempts to add security based on watermarking to LEACH routing protocol. To this end, we simulated and evaluated our WSN before and after falsification and we implemented our Watermarking-LEACH approach to evaluate the effectiveness in terms of integrity by evaluating the false negative rate (FNR) and in terms of energy-efficient through computing the energy consumption and compared its performance against other works by evaluating remaining energy metric across using the COOJA Simulator.
