A Secure and Efficient Method to Protect Communications and Energy Consumption in IoT Wireless Sensor Networks

The rapid growth of technology has resulted in the deployment a large number interconnected devices, resulting wide range new societal services. Wireless sensor networks (WSNs) are promising which is faced with challenges operating nodes, information gathering, data transmission, and providing means to act different scenarios such as monitoring, surveillance, forest fire detection, many others from civil military spectrum. scenario, nature sensor-equipped their communication methods make this architecture extremely vulnerable attacks, tampering, manipulation than conventional networks. Therefore, an optimal solution ensure security captures major constraints network terms energy utilization, secured bandwidth, memory fingerprint process required. This work proposes fast, reliable, secure method key distribution management that can be used integrity wireless networks’ communications. Moreover, regards efficient improvement Low Energy Adaptive Clustering Hierarchy (LEACH) algorithm (a cluster routing protocol mainly WSN) been proposed enhance efficiency, simplicity, load-balancing features. paper, we propose combination distributed exchange based on elliptic curve cryptography node improved LEACH demonstrate better performance parameters lifespan, dead consumption.
