Isolation points: Creating performance-robust enterprise systems
Mohamed S. Mansour, Karsten Schwan, Sameh Abdelaziz
Article No.: 10
DOI: 10.1145/1516533.1516534

This article explores a performance isolation-based approach to creating robust distributed applications. For each application, the approach is to understand the performance dependencies that pervade it and then impose constraints on the possible...

On the use of memory and resources in minority games
Ricardo M. Araujo, Luis C. Lamb
Article No.: 11
DOI: 10.1145/1516533.1516535

The use of resources in multiagent learning systems is a relevant research problem, with a number of applications in resource allocation, communication and synchronization. Multiagent distributed resource allocation requires that agents act on...

Semantics-based context-aware dynamic service composition
Keita Fujii, Tatsuya Suda
Article No.: 12
DOI: 10.1145/1516533.1516536

This article presents a semantics-based context-aware dynamic service composition framework that composes an application through combining distributed components based on the semantics of components and contexts of users. The proposed framework...

Exploiting user location for load balancing WLANs and improving wireless QoS
George Alyfantis, Stathes Hadjiefthymiades, Lazaros Merakos
Article No.: 13
DOI: 10.1145/1516533.1516537

A “Smart Spaces System”, called MITOS, for improved user connectivity in large wireless LAN installations is proposed. MITOS extends the scope of resource management to the dynamic relocation of nomadic users: the system suggests to a...

Self-adaptive software: Landscape and research challenges
Mazeiar Salehie, Ladan Tahvildari
Article No.: 14
DOI: 10.1145/1516533.1516538

Software systems dealing with distributed applications in changing environments normally require human supervision to continue operation in all conditions. These (re-)configuring, troubleshooting, and in general maintenance tasks lead to costly...
