Enhanced Reliable Broadcasting Protocols in Large Scale Mobile Ad Hoc Networks
Broadcast is an important and indispensable issue in Mobile Ad Hoc NETworks (MANETs). However, maintaining low protocol overhead and guaranteeing complete message delivery in broadcasting within the entire network is one of the most challenging tasks in MANET like environments. In this paper, the authors have proposed three efficient, scalable and reliable broadcasting protocols where every node is guaranteed to receive the message with low overhead and minimal cost. In Reliable Broadcasting Protocol-1 (RBP-1), the scalability and reliability of broadcast transmission is ensured by composing the entire network in a hierarchy of grids and through selective acknowledgments. Enhanced Reliable Broadcasting Protocol-1 (ERBP-1) incurs less number of packet forwarding than RBP- 1 by sending messages in reverse order of RBP-1.
