Collaborative Mobile Working

• Introduction
• Why do we need the collaborative mobile working?
• Exchanging, locating and sharing information
• Communicating with co-workers
• What is MOTION?
• The mobile Teamwork Infrastructure for
  Organizations Networking
• It Provides mobile teamwork support requirements
  such as locating distributed document and
  expertise, community building, and mobile
  information sharing and access.

3
Collaborative Mobile Working

• In the areas of mobile and collaborative
  systems,covers a wide range of topics from formal
  verifiable models of collaboration to dynamic
  migration and replication. These two areas are
  mostly contained within the larger area of
  distributed systems.

Collaborative Mobile Working

• MOTION Architecture

Presentation Layer
TWS API
TWS Layer
The bottom layer (The communication middleware)
The user interface
Teamwork Services layer
Basic communication Services
Peer to peer file sharing and
distributed search Publish/Subscribe mechanisms
5
Publish/Subscribe in MOTION

• Publish/Subscribe component in TWS
• Wraps the underlying middleware
• Gives a uniform and consistent view of the event
  concept to the application layer
• Subscription gateway
• Denote the set of callback components
• Be configuration for each user
• Two classes of subscription
• System Subscription
• User subscriptions
• User Specialized callbacks
• It is a component that handles subscriptions of a
  specific user

Collaborative Mobile Working

• The XQL query with a client
• /UserProfile (User/Expertise/ contains
  valve design) and System/Access/Status
  equals online/ID
• The XML description
• Example event.xml

9
Collaborative Mobile Working

• Related approaches and design decisions
• Khronika, Interlocus, Awarenesswork, Nessie
• Client-server based
• Do not support for distributed searching
• Do not concerned with device and user mobility
• PeerWare systems in MOTION
• P2P architectural style has been increasingly
  gaining attention
• P2P style provides high flexibility and systems
  configurability
• Provides both distributed searching/P2P file
  sharing and publish/subscribe support

10

• Requirements for an publish/Subscribe middleware
• An efficient filtering mechanism
• The capability to automatically destroy a
  subscription after a given delay
• Authorization mechanisms for subscriptions
• An expressive query language for defining
  subscriptions

Collaborative Advertising over Internet with
Agents

• Introduction
• Mobile device
• Implementation of information
• E-commerce service
• Basic restriction
• Limited capabilities
• High connection cost
• Low bandwidth
• High precision of the information delivered

Advertising over Internet

• Main problem in advertising services and products
  
• Finding potential customers
• Making the customers aware about the offers
• The solution
• The personal contact approach(one-to-one
  marketing)
• The mass media approach(one-to-many marketing)
• WAP-based communication
• Main problems in WAP-based communication
• User are not willing to disclose their private
  preferences to somebody that they dont
  completely trust.
• User are not willing to receive irrelevant
  information to a small screen

15
Software Agent

• Agent , advertising desk and users WML deck

16
Software Agent

• Basic advantages of the software agent
• The privacy of user preferences
• Off-line processing
• Pro-active filtering
• Analysis of offers as well as relaxing necessity
  for discovering target groups by advertisers.
• Real-time reaction to the proposed offer

17
Agora Framework

• Agora is a cooperative node in the Internet where
  agents can register their interests and get a
  support for matchmaking, negotiation,
  coordination and communication.
• Each cooperative node has a manager agent,
  coordinator, negotiator and communicator.
• The manager performs registration, matchmaking,
  and events handling.
• The coordinator and negotiator arte agents which
  manage some coordination or negotiation protocol.
• The communicator supports communication between
  agents and Agoras, also between different agents.

18
Agora Framework

• All the components of the cooperative can be
  overridden when needed.
• The Agora systems provides API for generation and
  customization of the cooperative nodes.
• The default agent in the Agora systems has goal
  analyzer, planner, knowledge base and
  communication.
• All the components can be customized or
  overridden.
• Their functionality can be different for
  different application.

Relevant Technologies

• Collaborative Systems strategies of human
  cooperation over the Web, computer platforms and
  architectures in support of remote cooperation,
  mediators, wrappers, design and implementation
  issues of collaborative applications
• Workflow Systems workflow architectures in
  support of collaboration processes, modeling of
  cooperation processes, truly distributed
  enactment services and interoperability of
  workflow engines, dynamic modification of running
  workflows
• Electronic Business establishment of contacts,
  suppliers search and negotiation, contract
  negotiations, Business-to-Business and
  Business-to-Employee cooperation support,
  establishment and coordination of virtual
  enterprises, shared business processes.
• Data-web Technology and Database Infrastructure
  for collaboration Web access to databases
  including Java Database Connectivity, database
  Web servers, Web interfaces to databases,
  database Web applications
• Interoperability Infrastructures compositional
  software architectures in support of
  collaboration, combining distributed object
  management platforms with Web and Java for
  cooperative applications, middleware
  infrastructures, describing metadata on the Web,
  providing semantic interoperability through
  metadata, emerging interoperability standards
