Resource-Considerate Data Routing Through Satellite Networks

C = network connectivity C = total journey cost D = matrix of maximum communication range between nodes (Rn×n) E = set of edges in G EG = subset of edges in G G = graph containing all nodes and edges G = evolving graph H = number of hops in a journey J = set of feasible journeys J = journey between nodes J = highest-value journey M = total number of edges in G m = number of edges in G N = total...

Cost Based Data Dissemination in Satellite Networks

We consider the problem of data dissemination in a satellite network. In contrast to previously studied models, broadcasting is among peers, rather than client server. We introduce a cost model for data dissemination in peer to peer satellite networks. The model quantifies the tradeoff between the inconsistency of the data, and its transmission cost; the transmission cost may be given in terms ...

Baras Department of Electrical and Computer Engineering Satellites are now being used to carry Internet traffic which brings new opportunities as well as new challenges to the satellite industry. Our goal in this...

Cellular Networks, Satellite Communication 1 Satellite Communication

A satellite communications system is based on antennas in a stable orbit above the earth. Satellites serve as relay stations in the sky. The basic idea of satellite communications is that two stations on earth discuss via one or more satellites. So a little bit of satellite-related terminology: 1. Earth station is an antenna on or near the surface of the earth. 2. Uplink is a transmission from ...
