Engineering Pervasive Service Ecosystems: The SAPERE Approach
Gabriella Castelli, Marco Mamei, Alberto Rosi, Franco Zambonelli
Article No.: 1
DOI: 10.1145/2700321

Emerging pervasive computing services will typically involve a large number of devices and service components cooperating together in an open and dynamic environment. This calls for suitable models and infrastructures promoting spontaneous,...

Online Automated Synthesis of Compact Normative Systems
Javier Morales, Maite López-sánchez, Juan A. Rodriguez-Aguilar, Wamberto Vasconcelos, Michael Wooldridge
Article No.: 2
DOI: 10.1145/2720024

Most normative systems make use of explicit representations of norms (namely, obligations, prohibitions, and permissions) and associated mechanisms to support the self-regulation of open societies of self-interested and autonomous agents. A key...

Reliable Task Allocation with Load Balancing in Multiplex Networks
Yichuan Jiang, Yifeng Zhou, Yunpeng Li
Article No.: 3
DOI: 10.1145/2700327

In multiplex networks, agents are connected by multiple types of links; a multiplex network can be split into more than one network layer that is composed of the same type of links and involved agents. Each network link type has a bias for...

SHõWA: A Self-Healing Framework for Web-Based Applications
João Paulo Magalhães, Luis Moura Silva
Article No.: 4
DOI: 10.1145/2700325

The complexity of systems is considered an obstacle to the progress of the IT industry. Autonomic computing is presented as the alternative to cope with the growing complexity. It is a holistic approach, in which the systems are able to configure,...

A Reinforcement Learning Approach for Interdomain Routing with Link Prices
Peter Vrancx, Pasquale Gurzi, Abdel Rodriguez, Kris Steenhaut, Ann Nowé
Article No.: 5
DOI: 10.1145/2719648

In today’s Internet, the commercial aspects of routing are gaining importance. Current technology allows Internet Service Providers (ISPs) to renegotiate contracts online to maximize profits. Changing link prices will influence interdomain...

Self-Tuning Batching with DVFS for Performance Improvement and Energy Efficiency in Internet Servers
Dazhao Cheng, Yanfei Guo, Changjun Jiang, Xiaobo Zhou
Article No.: 6
DOI: 10.1145/2720023

Performance improvement and energy efficiency are two important goals in provisioning Internet services in datacenter servers. In this article, we propose and develop a self-tuning request batching mechanism to simultaneously achieve the two...
