Abstract. The incredible growth in the capabilities and functionality
of mobile devices has enabled new applications to emerge. Due to the
potential for node mobility, along with significant node heterogeneity,
characteristics such as very large delays, intermittent links and high link
error rates pose a new set of challenges. Along with these challenges,
end-to-end paths are assumed not to exist and message relay approaches
are often adopted. While message flooding happens to be a simple and
robust solution for such cases, its cost in terms of network resource con-
sumption is unaffordable. In this paper, we focus on the evaluation of
different controlled message flooding schemes over large-scale, sparse mo-
bile networks. We study the effect of these schemes on message delay and
network resource consumption. Our simulations show that our schemes
can save substantial network resources while incurring a negligible in-
crease in the message delivery delay.
