Preliminary Call for Papers for the

Fourth International Workshop on Agents and Peer-to-Peer Computing 
(AP2PC 2005)
http://p2p.ingce.unibo.it/
held in AAMAS 2005
International Conference on Autonomous Agents and MultiAgent Systems
Utrecht University, Netherlands.
from 25 July - 29 July 2005.

CALL FOR PAPERS
Peer-to-peer (P2P) computing has attracted enormous media attention, 
initially spurred by the popularity of file sharing systems such as 
Napster, Gnutella, and Morpheus. Systems like BitTorrent and eDonkey 
have continued to sustain that attention. The peers are autonomous, or 
as some call them, first-class citizens. P2P networks are emerging as a 
new distributed computing paradigm for their potential to harness the 
computing power of the hosts composing the network and make their 
under-utilized resources available to others. New techniques such as 
distributed hash-tables (DHTs), semantic routing, and Plaxton Meshes are 
being combined with traditional concepts such as Hypercubes, Trust 
Metrics and caching techniques to pool together the untapped computing 
power at the "edges" of the internet. These new techniques and 
possibilities have generated a lot of interest in many industrial 
organizations recently, and has resulted in the creation of a P2P 
working group for undertaking standardization activities in this area. 
(http://www.irtf.org/charters/p2prg.html).

In P2P computing peers and services organise themselves dynamically 
without central coordination in order to foster knowledge sharing and 
collaboration, both in cooperative and non-cooperative environments. The 
success of P2P systems strongly depends on a number of factors. First, 
the ability to ensure equitable distribution of content and services. 
Economic and business models which rely on incentive mechanisms to 
supply contributions to the system are being developed, along with 
methods for controlling the "free riding" issue. Second, the ability to 
enforce provision of trusted services. Reputation based P2P trust 
management models are becoming a focus of the research community as a 
viable solution. The trust models must balance both constraints imposed 
by the environment (e.g. scalability) and the unique properties of trust 
as a social and psychological phenomenon. Recently, we are also 
witnessing a move of the P2P paradigm to embrace mobile computing in an 
attempt to achieve even higher ubiquitousness. The possibility of 
services related to physical location and the relation with agents in 
physical proximity could introduce new opportunities and also new 
technical challenges.

Although researchers working on distributed computing, MultiAgent 
Systems, databases and networks have been using similar concepts for a 
long time, it is only fairly recently that papers motivated by the 
current P2P paradigm have started appearing in high quality conferences 
and workshops. Research in agent systems in particular appears to be 
most relevant because, since their inception, MultiAgent Systems have 
always been thought of as networks of peers.

The MultiAgent paradigm can thus be superimposed on the P2P 
architecture, where agents embody the description of the task 
environments, the decision-support capabilities, the collective 
behavior, and the interaction protocols of each peer. The emphasis in 
this context on decentralization, user autonomy, ease and speed of 
growth that gives P2P its advantages, also leads to significant 
potential problems. Most prominent among these problems are 
coordination: the ability of an agent to make decisions on its own 
actions in the context of activities of other agents, and scalability: 
the value of the P2P systems lies in how well they scale along several 
dimensions, including complexity, heterogeneity of peers, robustness, 
traffic redistribution, and so on. It is important to scale up 
coordination strategies along multiple dimensions to enhance their 
tractability and viability, and thereby to widen the application 
domains. These two problems are common to many large-scale applications. 
Without coordination, agents may be wasting their efforts, squander 
resources and fail to achieve their objectives in situations requiring 
collective effort.

This workshop will bring together researchers working on agent systems 
and P2P computing with the intention of strengthening this connection. 
Researchers from other related areas such as distributed systems, 
networks and database systems will also be welcome (and, in our opinion, 
have a lot to contribute). We seek high-quality and original 
contributions on the general theme of "Agents and P2P Computing". The 
following is a non-exhaustive list of topics of special interest:

- Intelligent agent techniques for P2P computing
- P2P computing techniques for MultiAgent Systems
- The Semantic Web, Semantic Coordination Mechanisms and P2P systems
- Scalability, coordination, robustness and adaptability in P2P systems
- Self-organization and emergent behavior in P2P networks
- E-commerce and P2P computing
- Participation and Contract Incentive Mechanisms in P2P Systems
- Computational Models of Trust and Reputation
- Community of interest building and regulation, and behavioral norms
- Intellectual property rights in P2P systems
- P2P architectures
- Scalable Data Structures for P2P systems
- Services in P2P systems (service definition languages, service 
discovery, filtering and composition etc.)
- Knowledge Discovery and P2P Data Mining Agents
- P2P oriented information systems
- Information ecosystems and P2P systems
- Security issues in P2P networks
- Pervasive computing based on P2P architectures (ad-hoc 
networks,wireless communication devices and mobile systems)
- Grid computing solutions based on agents and P2P paradigms
- Legal issues in P2P networks PANEL
The theme of the panel will be Decentralised Trust in P2P and MultiAgent 
Systems. As P2P and MultiAgent systems become larger and more diverse 
the risks of interacting with malicious peers become increasingly 
problematic. The panel will address how computational trust issues can 
be addressed in P2P and MultiAgent systems. The panel will involve short 
presentations by thepanelists followed by a discussion session involving 
the audience.

IMPORTANT DATES
Paper submission: 14th March 2005
Acceptance notification: 18th April 2005
Workshop: 25-26th July 2005
Camera ready for post-proceedings: 17th August 2005

REGISTRATION
Accomodation and workshop registration will be handled by the AAMAS 2005 
organization along with the main conference registration.

SUBMISSION INSTRUCTIONS
Unpublished papers should be formatted according to the LNCS/LNAI author 
instructions for proceedings and they should not be longer than 12 pages 
(about 5000 words including figures, tables, references, etc.).

A web submission interface will be provided shortly at 
http://p2p.ingce.unibo.it/

At the very least we would encourage all authors to read the abstracts 
of the papers submitted to previous workshops:

http://p2p.ingce.unibo.it/2002/ 
http://www.springeronline.com/sgw/cda/frontpage/0,11855,5-40109-22-2991818-0,00.html
http://p2p.ingce.unibo.it/2003/ 
http://www.springeronline.com/sgw/cda/frontpage/0,11855,5-40109-22-37060961-0,00.html
http://p2p.ingce.unibo.it/2004/

Particular preference will be given to novel approaches and those papers 
that build upon the contributions of papers presented at previous AP2PC 
workshops. In addition, on the workshop website we will present more 
precise details of how papers will be judged for inclusion. So please 
check http://p2p.ingce.unibo.it/ before your final submission.

PUBLICATION
Accepted papers will be distributed to the workshop participants as 
workshop notes. As in previous years post-proceedings of the revised 
papers (namely accepted papers presented at the workshop) will be 
submitted for publication to Springer in Lecture Notes in Computer 
Science series.
