Security Aware Fuzzy C-Means Cluster-based Social Spider Elliptic Curve Cryptography (FSER) Routing Protocol in FSO MANET

Objective: To design an FSER (Fuzzy _means cluster-based Social spider Elliptic Curve Cryptography Routing) protocol to enhance the security and prevent the loss of data while routing in FSO MANET. Methods/Statistical Analysis: Our proposed protocol scheme is based on three stages: (i) Cluster formation stage, (ii) Network routing stage and (iii) Secure communication stage. In the first stage, an efficient Fuzzy c-means (FCM) clustering process is used to form clusters in FSO MANET. In the second stage, Social Spider Algorithm (SSA) is used to create the routing table through vibration to other spiders based on the distance from the members and efficient routing through vibration intensity of spiders in the web. In the third phase, we suggest an Elliptic Curve Cryptography (ECC) Algorithm for MANET to provide secure data delivery from source to destination. Findings: A hierarchal secure FSER routing protocol for FSO MANET is proposed. Nowadays, MANETs are demanding higher bandwidths, smarter and faster. In this paper, the higher demands on growing application can be supported using FSO which has the advantage of low power consumption and higher bandwidth to support huge number of nodes. First, a temporary topology is created by forming clusters with cluster head in order to consume the energy in which each node having multiple transceivers. Then a quality aware routing is performed by checking the path for QoS demand from source to destination. A secure data delivery from source to destination is provided by encrypting the packets using the ECC authentication scheme. Improvements/Application: Experimental simulations on FSO MANETs are implemented in MATLAB tool by finding an optimal path to demonstrate the effectiveness of the proposed FSER protocol that fulfills several Quality of Service (QoS) constraints. The designed proposed protocol in FSO is observed to be performing well with high speed optical modulation for bandwidth intensive applications like multimedia.
