Enhancing Performance of Duo Coverage Broadcasting in MANET

Author : R.Thanga Nishar
Volume 1 No.1 January-June 2012 pp 69-75

Abstract

In today’s developing environment in the field of Mobile Ad hoc Network, broadcast reliability plays vital role. In MANET when the forwarding nodes are not carefully designated, they are prone to the broadcast storm. To avoid the problem of broadcast storm, the Double Coverage Broadcasting (DCB) algorithm is introduced. The proposed scheme increases the delivery ratio though the redundancy is reduced. Other factors under consideration is that the proposed scheme has high delivery ratio, low forwarding ratio, low overhead and low end-to-end delay for a broadcast operation under a high transmission error rate. Among the 1-hop neighbours of the sender, only selected forwarding nodes retransmit the broadcasting the message. Forwarding nodes are selected in such a way that 1) the sender’s 2-hop neighbours are covered and 2) the sender’s 1-hop neighbours are either forwarding nodes or nonforwarding nodes covered by at least two forwarding neighbours. The retransmissions of the forwarding nodes are received by the sender as the confirmation of their reception of the packet. The nonforwarding 1-hop neighbours of the sender do not acknowledge the reception of the broadcast. If the sender does not detect all its forwarding nodes’ retransmissions, it will resend the packet until the maximum number of retries is reached.
