Immediate Family ACK Tree for Reliable Multicast in Mobile Ad Hoc Networks
Abstract—In this paper, an efficient protocol, called Immediate Family ACK Tree (IFA), is proposed to report correct data reception or a negative acknowledgment to request retransmissions for feedback.. Each reliable multicast protocol needs a recovery mechanism to deal with occasional losses, duplications and failed delivery of datagram. IFA use a directly-related based recovery mechanism that localizes ACKs and retransmissions to avoid forward and feedback flooding. Our approach constructs an immediate ACK tree to three generations of nodes and uses efficient Fast-Upstream recovery algorithm to maintain reliable multicast and reduce overhead. The results show that IFA achieves better performance a high reliability in a mobility mode, a scalability performance in a large ad hoc network, and high delivery efficiency in RTQ multicast due to the speedy of recoverable service.
Index Terms—Immediate family ACK tree (IFA), mobile ad hoc network, reliable multicast.
