Ubiquitous networking allows users to access and exchange information freely from anywhere using broadband and mobile access. It combines optical communication, mobile, and consumer electronics into one network. A ubiquitous network is context-aware, connecting computing devices anywhere and anytime through objects. The key role is fulfilling user needs through context awareness of their location, access status, and preferences to provide optimal services. Main challenges include providing seamless connectivity, context awareness, resource and device management across this integrated network.

1. Ubiquitous Networking
Next Generation Service Platform

2. 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 .

3. 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

4. What is Ubiquitous Networking ?
 Ubiquitous : Omnipresence
 Computing Everywhere
 Content Everywhere
 Connectivity Everywhere
 Seamless Connection and Service
 Location, Context & Preference-Aware Service

5. 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.

6. Applications Of Ubiquitous Networking
Use of Ubi-net in Household

7. Applications Of Ubiquitous Networking
Use of Ubi-net in GPS car tracking system

8. 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.

9. Enablers
9
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.

12. Challenges in Ubiquitous Network
Management
The main challenges in ubiquitous network management are :
 Seamless connectivity
 Context awareness
 Resource management
 Device management

13. Always-on connectivity
Network Interface Management
Interface co-existence
Challenges in Seamless
Connectivity

14. Challenges in context awareness
Management
 Filtering
 Context – composition
 Adaptation
 Discovery of context
 Storage of context
 Access control on context

15. 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

16. Challenges in Device
Management:
Device Identification
Device adaptability
Device Tracking

17. 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.
