Abstract In Opportunistic Networks (OppNets), network partition and discon-
nections are very common as nodes may move out of the radio range of each other.
So, routing and forwarding in these networks is a very challenging task. However,
with the introduction of some infrastructure it is still possible to create a fully
connected network. This infrastructure is generally composed of some special
nodes that are more powerful in terms of energy, transmission range, buffer space,
etc., as compared to the normal nodes. The routing protocol proposed in this paper
uses the combination of both static as well as mobile infrastructure for message
passing between the nodes. The fixed infrastructure is used in form of infostations
(IS) and the mobile infrastructure in form message ferry (MF). This new protocol
is energy efficient, robust, and expected to reduce the routing overheads seen in the
previous protocols.
