Delay Tolerant Networking (DTN) has been proposed as a global overlay architecture to provide network connectivity in challenged environments such as deep-space communications field. Bundle Protocol along with its convergence layer protocols transform end-to-end reliability into questionable hop-by-hop reliable communication and imposes a two-tier routing policy that allows flexible routes only within...
Successful event detection in Wireless Sensor Networks (WSN) requires reliability and timeliness. When an event occurs, the base station (BS) is particularly interested about reliable and timely collection of data sent by the nodes close to the event, and the data sent by other nodes have little importance. In this paper, we propose Congestion Avoidance and Mitigation (CAM) protocol that performs...
This paper presents delay and throughput performance results for a "cache-and-forward" (CNF) network architecture for mobile content delivery services. The CNF network uses hop-by-hop transport and in-network storage to deliver large media files to mobile users. The CNF protocol is designed to deal with fluctuating wireless link quality and occasional periods of disconnection, and is therefore...
Internet Relay Chat (IRC) is a critical application in military networks for maintaining situational awareness and conducting battle management at all echelons. But these networks are often subject to frequent disconnections, limited bandwidth, and long delays, especially when using satellite services and field radios. Such conditions are inhospitable to TCP, and thus the standard IRC protocol, which...
