Content-Aware Transmission in UAV-Assisted Multicast Communication

Peer Assisted Content Distribution over Router Assisted Overlay Multicast

While multicasting is considered valuable for content distribution, it is not widely supported on the Internet, despite the emergence of scalable overlay schemes. Content providers have instead turned to peer assisted content distribution in order to efficiently serve large numbers of clients, thus removing the bandwidth bottleneck from their side but placing a heavy burden on the clients. Even...

Modeling Urban Environments for Communication Aware UAV Path Planning

The presented work introduces a graph based approach to model urban (or otherwise cluttered) environments for UAS utilization beyond line-of-sight as well as out of direct R/F range of the operator’s control station. Making the assumption that some a priori data of the environment is available, the proposed method uses a classification of obstacles with respect to their impact on UAV motion and...

Energy-Aware Secure Multicast Communication In Wireless Ad-Hoc Networks

In this paper we address the problem of efficiently securing multicast communication in energy constrained wireless ad hoc networks. We show that existing scalable key distribution techniques that rely on logical hierarchies, are energy inefficient. We show that great energy savings can occur when physical location information is considered in the key distribution scheme construction. We also s...

Towards an Application-Aware Multicast Communication Framework for Computational Grids

Multicast Communication in Multicomputer Networks Multicast Communication in Multicomputer Networks

EEcient routing of messages is the key to the performance of multicomputers. Mul-ticast communication refers to the delivery of the same message from a source node to an arbitrary number of destination nodes. While multicast communication is highly demanded in many applications, it is not directly supported by all existing multicom-puters; rather it is indirectly supported by multiple one-to-on...
