This paper focuses on replication in DHT based structured overlay networks, and presents a theoretical framework for optimal replication in such networks with respect to query frequency. In particular, we determine the optimal replication factor for query- ...
Due to the limited number of available IP addresses most computers on the Internet use dynamic IP addresses which causes problems for applications that have to maintain rout-ing tables, for example, peer-to-peer systems. To overcome this we propose unique ...
It is appealing to implement publish/subscribe systems in a peer to peer (P2P) manner to circumvent the scalability issues of broker-based (semi-decentralized) systems and simplify the deployment. While existing P2P generic infrastructures provide a scalab ...
Using location information to help routing is often proposed as a means to achieve scalability in large mobile ad-hoc networks. However, location based routing is difficult when there are holes in the network topology and nodes are mobile. Terminode routin ...
Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...
This paper provides a quantative comparison of the efficiency of the self-organized construction processes of the P-Grid and FreeNet peer-to-peer systems. Starting from a defined, realistic network topology we simulate the construction of their access stru ...
Load balancing apparatus for a data communications network comprises hash logic for computing a hash function on incoming data packets. A threshold detector is connected to the hash logic for triggering, in response to utilization of the downstream objects ...
In this thesis we study two routing problems related to mobility. The first problem concerns scalable multicast routing when there is a large number of multicast groups with a small number of receivers. Existing dense and sparse mode routing protocols have ...
In this paper, we argue that a broad range of large-scale network services would benefit from a scalable mechanism for delivering state about a random subset of global participants. Key to this approach is ensuring that membership in the subset changes per ...
The unprecedented growth of the Internet over the last years, and the expectation of an even faster increase in the numbers of users and networked systems, resulted in the Internet assuming its position as a mass communication medium. At the same time, the ...
