Modified Algorithms for Multilevel GRSB Protocol

— GRSB - Guaranteed, Reliable, Secure Broadcast - is a protocol that provides reliable and secure broadcast / multicast communications [1,2]. It can be implemented in many types of networks - local area networks, wide area networks, as well as satellite communications. The methodology used in this protocol is surprisingly simple. Three logical nodes are enforced in the network - a Central Retransmiter, a Designated Acknowledger, and a Playback Recorder(s). Through the coordinated service of the three nodes, every user node can be guaranteed to receive all broadcast messages in the correct temporal order. A fourth logical node, the Security Controller, can be added to the protocol to provide security-related services such as user authentication, message encryption, etc. In this paper, we have proposed a multilevel broadcast model of GRSB (Guaranteed, Reliable and Secure Broadcast) protocol , where 1st level broadcast mostly maintains the traditional GRSB model. 2nd level broadcast has...
