Collaborative Mobile Working

IntroductionWhy do we need the collaborative mobile working?

Exchanging, locating and sharing informationCommunicating with co-workers

What is MOTION?The mobile Teamwork Infrastructure for Organizations NetworkingIt Provides mobile teamwork support requirements such as locating distributed document and expertise, community building, and mobile information sharing and access.

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

Related approaches and design decisionsKhronika, Interlocus, Awarenesswork, NessieClient-server based Do not support for distributed searchingDo not concerned with device and user mobility

PeerWare systems in MOTIONP2P architectural style has been increasingly gaining attentionP2P style provides high flexibility and systems configurabilityProvides both distributed searching/P2P file sharing and publish/subscribe support

10

Requirements for an publish/Subscribe middleware1.An efficient filtering mechanism2.The capability to automatically destroy

a subscription after a given delay3.Authorization mechanisms for

subscriptions4.An expressive query language for

defining subscriptions

Collaborative Advertising over Internet with Agents

IntroductionMobile deviceImplementation of informationE-commerce serviceBasic restriction

Limited capabilitiesHigh connection costLow bandwidth

High precision of the information delivered

Advertising over Internet

14

Advertising over InternetMain problem in advertising services and products

Finding potential customersMaking the customers aware about the offers

The solutionThe personal contact approach(one-to-one marketing):The mass media approach(one-to-many marketing):

WAP-based communicationMain problems in WAP-based communication

User are not willing to disclose their private preferences to somebody that they don’t completely trust.User are not willing to receive irrelevant information to a small screen

15

Software Agent:Agent , advertising desk and user’s WML deck

16

Software Agent:

Basic advantages of the software agent

The privacy of user preferencesOff-line processingPro-active filteringAnalysis of offers as well as relaxing necessity for discovering target groups by advertisers.Real-time reaction to the proposed offer

Agora FrameworkAgora 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.
