Ubiquitous Networking

Next Generation Service Platform

Users expectation towards Next Generation

Users expectation toward the next generation service is not just to provide a large bandwidth.

They would rather expect to maintain or enhance their overall living environment, such as safety, security, amenity and feeling ease with the surrounding environment or within their community .

They are not aware which communication method they use .

Introduction to Ubiquitous network

Ubiquitous network is a context-aware network of computing devices which are connected at any place, anytime and with any object

Ubiquitous network allows all users to access and exchange information of any kind freely at anytime, from anywhere, and from any appliance through the use of broadband and mobile access.

Combines optical communication, mobile and consumer electronics into one network

What is Ubiquitous Networking ?

Ubiquitous : Omnipresence

Computing Everywhere Content Everywhere Connectivity Everywhere

Seamless Connection and Service Location, Context & Preference-Aware Service

The role of ubiquitous network

The role of ubiquitous network should seek for fulfilling such user needs in corporation with use terminal and service platform.

Keyword is “context awareness” for a user.Context means user’s general situation such as user’s

location, user’s access status, etc.By always keeping aware of user’s context, a system

can offer the best service that he/she wants.

Applications Of Ubiquitous Networking

Use of Ubi-net in Household

Applications Of Ubiquitous Networking

Use of Ubi-net in GPS car tracking system

Background and assumptions

Third generation cellular system is becoming dominant and person-to-person call is mostly made by cellular.

Fixed broadband services will come into home environment widely. Users will enjoy broadband access both at office and home.

Not only person-to-person communications, but other communications style such as machine-to-machine communications are gradually becoming popular.

Enablers

The following items are several possible enablers for ubiquitous networking paradigm;

Advent of high-end mobiles which support 3G capability, location, middleware environment, sensors, etc.

RFID technology with which man-to-environment interactions much easier.

Ontology which deals with objects on the Web more semantic way than ever.

Issues in Ubiquitous Network Management

Challenges in Ubiquitous Network Management

The main challenges in ubiquitous network management are :

Seamless connectivity Context awareness

Resource management

Device management

Always-on connectivity

Network Interface Management

Interface co-existence

Challenges in Seamless Connectivity

Challenges in context awareness Management

Filtering Context – composition Adaptation Discovery of context Storage of context Access control on context

Challenges in Resource Management

Resource Dissemination: Information about machine resources

Resource Discovery :Mechanism by which applications find resource information Scheduling Resources: Grids (Large scale

network computing system) decide which resources are assigned to which jobs

Challenges in Device Management:

Device Identification

Device adaptability

Device Tracking

Flexible service platform is the key

From the ubiquitous service point of view, an ubiquitous network should have:Flexible service platform execution

environment with common API, Super high performance switching and

routing capability,Broadband service capability,Relevant adaptive routing mechanism.
