Distributed computational grids depend on TCP to ensure reliable end-to-end communication between nodes across the wide-area network (WAN). Unfortunately, TCP performance can be a...
This paper proposes a study of the IPTV world, focusing on network and system architectures, video codecs, network protocols, services and quality assurance. Based on this study, a...
In this paper, we present an analytical model for the approximate calculation of the throughput and end-toend delay performance in single hop and multihop IEEE 802.11 networks unde...
The efficacy of data aggregation in sensor networks is a function of the degree of spatial correlation in the sensed phenomenon. While several data aggregation (i.e., routing with...
In this paper we propose a lightweight algorithm for constructing multi-resolution data representations for sensor networks. We compute, at each sensor node u, O(log n) aggregates...
