N2 - The Internet protocols were designed for a primarily "fixed" and relatively static network environment where communication links are stable and exhibit fairly uniform communication characteristics. Mobile wireless communication has fundamentally invalidated some of these assumptions, for (heterogeneous) wireless access networks and even more so for mobile ad-hoc networks (MA-NETs) formed between mobile users: from highly variable link characteristics to temporary disconnections to non-existing end-to-end paths. While many activities have focused on the link and network layer to provide seamless and ubiquitous connectivity for mobile users, thus mimicking the fixed Internet, and transport layer optimizations have addressed performance issues and connection persistence in wireless networks, application protocols have received rather little attention. However, the semantics of many of today's non-real-time applications are perfectly compatible with partly connected and disruptive mobile environments, it is just the protocol designs that are not. We identify issues with present application protocols and discuss requirements to make them workable in challenged mobile environments, leveraging Delay-tolerant Networking (DTN) as underlying communication paradigm and augmenting server-based operation by peer-to-peer communications.
