The broadcast operation, as a fundamental service in Mobile Adhoc NETworks (MANETs), is prone to the broadcast storm problem if forwarding nodes are not carefully designated. The objective of reducing broadcast redundancy, while providing high delivery ratio under high transmission error rate is a major challenge in MANETs. This paper proposes a simple broadcast algorithm, called Enhanced Double-Covered Broadcast (EDCB), which takes advantage of broadcast redundancy to improve the delivery ratio in an environment that has rather high transmission error rate.
