- Distributed, Secure Load Balancing With Skew, Heterogeneity, and Churn
- Numerous proposals exist for load balancing in peer-to-peer (p2p) networks. Some focus on namespace balancing, making the distance between nodes as uniform as possible. This technique works well under ideal conditions, but not under those found empirically. Instead, researchers have found heavy-tailed query distributions skew, high rates of node join...

- Resource Biased Path Selection in Heterogeneous Mobile Networks
- In wireless ad hoc networks heterogeneity is inherent; each node has different characteristics, resources and purpose. Current ad hoc routing protocols do not take node heterogeneity into account when making routing decisions; they consider each node identical in capabilities. This paper proposes a simple way to modify the route discovery...

- Federation Supplements The Data Warehouse - Not Either/Or, Never Was
- Few enterprise data warehousing EDW professionals regard the key rival approach--data federation--to be a best practice. Usually, the reasons for this disdain are valid, such as the fact that federated environments are not optimized for heavy-hitting data matching, merging, transformation and cleansing, all of which are essential functions to deliver...

- Addressing Heterogeneity, Scalability, and Privacy in Layered Multicast Congestion Control
- Multicast is attracting a resurgence of interest because it has a potential to address the explosively growing need for efficient streaming of large-volume Internet content. However, to realize the potential, large-scale multicast distribution requires effective congestion control. This paper designs SIM, a protocol that combines three distinct mechanisms (Selective participation,...

- Load Balancing for Multimedia Streaming in Heterogeneous Peer-to-Peer Systems
- Multimedia streaming of mostly user generated content is an ongoing trend, not only since the upcoming of Last.fm and YouTube. A distributed decentralized multimedia streaming architecture can spread the traffic costs to the user nodes, but requires providing for load balancing and consider the heterogeneity of the participating nodes. This...

- Load Balancing in Dynamic Structured P2P Systems
- This paper proposes an algorithm for load balancing in such heterogeneous, dynamic P2P systems. This simulation results show that in the face of rapid arrivals and departures of objects of widely varying load, this algorithm achieves load balancing for system utilizations as high as 90% while moving only about 8%...
