ABSTRACT

A Mobile Adhoc Network (MANET) is a collection of autonomous nodes that communicate with each other ,most frequently using a multi-hop wireless network. Secure and multicast group communication is an active area of research in MANETS. The main problem in secure group communication is group dynamics and key management. Group key management is crucial for multicast security. Member joining and member leaving from the group is the main challenge in designing secure and scalable group communication for dynamic update of keys. Most of the proposed solutions for wired networks are not considering this parameter and so suffer from the one-affects-n scalability problem. This paper presents the simulation of A Novel Scalable Group Key Management Protocol (NSGKMP) for wireless Adhoc Networks and demonstrates the simulation results through NAM(Network Animator) in NetworkSimulator2 (NS2). This NSGKMP for MANETs approach decreases number of rekeying operations when a member joins in to the group or leaves from the group i.e. dynamic updating of keys.
