Clustering and Securing IoT Wireless Sensor Network

One of the future rising technologies is Internet of Things (IoT) that will play a significant role in linking the world. IoT is a group of a huge number of interrelated networks including Wireless Sensor Network (WSN). IoT makes use of speedily developing devices and technologies. A large number of unlimited interconnections of numerous technologies in IoT makes privacy and safety of data as a matter of concern. WSN makes use of Low Energy Adaptive Clustering Hierarchy (LEACH) for the purpose of construction of sensor networks that are energyefficient. These networks are likely to a huge number of attacks including HELLO flood attack. This paper presents a novel protocol named CS-LEACH (Cyclic Secure LEACH) for securing cluster head from Hello flood attack as an extension to LEACH protocol. CS-LEACH makes use a unique Cyclic number, an exclusive ID and RBG color cube numbers for each sensor node so as to authenticate one of the nodes as CH. The CS-LEACH is executed by making use of NS2 simulator for the purpose of proving its efficiency.
