ABSTRACT
Mobile Ad Hoc Networks (MANETs) provide rapidly deployable
and self­configuring network capacity required in many critical ap­
plications, e.g., battlefields, disaster relief and wide area sensing. In
this paper we study the problem of efficient data delivery in sparse
MANETs where network partitions can last for a significant period.
Previous approaches rely on the use of either long range commu­
nication which leads to rapid draining of nodes' limited batteries,
or existing node mobility which results in low data delivery rates
and large delays. In this paper, we describe a Message Ferrying
(MF) approach to address the problem. MF is a mobility­assisted
approach which utilizes a set of special mobile nodes called mes­
sage ferries (or ferries for short) to provide communication ser­
vice for nodes in the deployment area. The main idea behind the
MF approach is to introduce non­randomness in the movement of
