An efficient mobility aware stable and secure clustering protocol for mobile ADHOC networks

Energy efficiency and security are considered as two crucial issues in the design of MANET. In this paper, an energy efficient stable as well as secure clustering (EESSC) technique is presented for MANET. The presented EESSC technique makes use of fuzzy logic mechanism to select the cluster heads (CHs) properly by the use of five variables namely remaining energy level, node degree, distance, trust level and node mobility. In addition, a standby CH (SBCH) is also introduced to find useful in case of accidental cases like CH dies, CH moves out of the cluster or CH is comprises. In such case, SBCH is invoked to act as CH and again another SBCH is chosen. This process helps to achieve network availability with no disturbances along with the additional level of security. The simulation of the EESSC takes place under diverse aspects and the outcome verified the betterment of the presented model over the compared ones. From the simulation outcome, under the simulation time of 250 s, the CH changes takes place by 19 times whereas a maximum of 28 and 30 CHs were changed by the existing EWCA and EESSC methods respectively.
