Reliable broadcast scheme initiated by receiver in ad hoc networks

摘要

In mobile ad hoc network, every link is wireless and every node is mobile. Those features make data lost easily as well as broadcasting inefficient and unreliable. Moreover, efficiency and reliability is conflicting with each other. Hence it is hard to achieve efficiency and reliability at the same time with just one scheme. In this paper, we present the scheme to improve the reliability and efficiency of the broadcast protocol in mobile ad hoc network. This scheme, unlike flooding which keeps reliability by sending excessive redundant packets, improves delivery rate with minimum overhead without degrading efficiency.
