Mobility plays a major role in mobile ad hoc networks (MANETs),
since it stresses networking tasks such as routing on the one hand,
but aids to increase the network capacity and to overcome network
partitioning on the other hand. To benefit from node mobility, a new
class of MANET protocols and applications are designed to be
delay-tolerant and mobility-aided. The main communication paradigm
here is store-and-forward. For delay-tolerant mobility-aided
networking, mobility on a large time-scale is a key feature. So far
however, a few work is done to adapt store-and-forward concepts to
the large time-scale mobility.
Our first step that simplifies the adaptation to node mobility, is a
set of novel mobility metrics. These metrics quantify the mobility
on a large time-scale and are based on the pair-wise contacts
between mobile nodes. In this paper, we show how to exploit these
mobility metrics to design an efficient buffering strategy for
hypergossiping, a delay-tolerant mobility-aided MANET broadcasting
protocol. The novel buffering strategy detects relevant mobility
patterns at run-time, using contact-based mobility metrics, and
adapts the buffering decision to the detected mobility pattern.
