Toward Broadcast Reliability in Mobile Ad Hoc Networks with Double Coverage. (A New TCP for Persistent Packet Reordering).
Abstract:
The broadcast operation, as a fundamental service in mobile ad hoc networks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy while still providing high delivery ratio under high transmission error rate is a major challenge in MANETs. In this paper, we propose a simple broadcast algorithm, called double-covered broadcast (DCB), which takes advantage of broadcast redundancy to improve the delivery ratio in an environment that has rather high transmission error rate. The retransmissions of the forwarding nodes are received by the sender as the confirmation of their reception of the packet. If the sender does not detect all its forwarding nodesâ„¢ retransmissions, it will resend the packet .as a result the proposed broadcast algorithm provides good performance under a high transmission error rate environment.
