Opportunistic routing is the major routing strategy for intermittently connected networks (ICNs) that are characterized by frequent link disruptions. These disruptions limit the formation and stability of continuous end-to-end paths between any arbitrary source-destination node pair. This paper proposes a novel opportunistic routing/forwarding protocol, Nodes Density Adaptive Opportunistic (NDAO)...
The introduction of intelligent devices with short range wireless communication techniques has motivated the development of Mobile Ad hoc NETworks (MANETs) during the last few years. However, traditional end-to-end based routing algorithms designed for MANETs are not much robust in the challenged networks suffering from frequent disruption, sparse network density and limited device capability. Such...
We study a mobile wireless network where groups or clusters of nodes are intermittently connected via mobile "carriers'' (the carriers provide connectivity over time among different clusters of nodes). Over such networks (an instantiation of a delay tolerant network), it is well-known that traditional routing algorithms perform very poorly. In this paper, we propose a two-level Back- Pressure...
