Leveraging MAC-layer information for single-hop wireless transport in the Cache and Forward Architecture of the Future Internet

— Cache and Forward (CNF) Architecture is a novel architecture aimed at delivering content efficiently to potentially large number of intermittently connected mobile hosts. It uses a reliable hop-by-hop transport mechanism where in-network storage is leveraged to store the entire file in each node, before forwarding it towards the destination(s). Links between nodes may be wired, or wireless, 802.11 a/b/g, cellular, or satellite, or some other upcoming wired/wireless technology. A key aspect in the CNF architecture is to choose the link-layer protocol with parameters such that it optimizes the performance of the link between two CNF nodes. In this paper we propose Cross-Layer Aware Transport Protocol (CLAP) as a potential candidate for a reliable link-layer protocol between two CNF nodes connected by 802.11 a/b/g link. Leveraging upon MAC layer status information, CLAP quickly adapts its flow control rate to bandwidth fluctuations and maximizes link utilization efficiency. Due to the...
