SECURE MULTICAST COMMUNICATION USING GROUP BASED MULTICAST HIERARCHY
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 5
Abstract
Secure multicast communication is a significant requirement in emerging applications in adhoc environments like military or public emergency network applications. Membership dynamism is a major challenge in providing complete security in such networks. This paper proposes a efficient Group Based Multicast Hierarchy (GBMH) algorithm for secret multicast communication, in which source nodes used the Secure Ad hoc On Demand Distance Vector (SAODV) protocol is an extension of the AODV protocol. The Secure AODV scheme is based on the assumption that each node possesses certified public keys of all network nodes. The SAODV protocol collects its 1 hop neighbours to form group. This protocol sends acknowledgement for each transmission in order to reduce the retransmission. Membership dynamism was overcome by electing local controllers and with periodic updates of node join and leave information using multicast hierarchy. The performance is studied in terms of average end to end delay and fault tolerance in multicast transmission.
