RFID & ubiquitous technology developers at IAP, comes up with robust and secure framework for tracebility and ubiquitous computing by utilizing the Ubiquitous Code Identification Technology.

Leveraging over the years of experience in implementing RFID, ubiquitous and enterprise system, this framework was developed to help clients in implementing the RFID functionality in their enterprise systems by picking off the shelf components.

The framework is scalable and it’s Product Information Servers, Authentication Servers, Data Mining Servers, Web Based Inventory Management System, Online Order Placement System, Client programs etc can be used to quickly develop and integrate the RFID functionality in the enterprise system.

It is compatible with one of the world’s most advance ubiquitous computing platform known as Ubiquitous Communicator.

a

Developing complex streaming system had always been a challenge for us until we developed our end to end system for multi-channel, multi platform streaming system compatible with handheld devices, PC as well as mobile devices. It is flexible, scalable to support principally unlimited number of connected cameras & concurrent users.

Multimedia Streaming Servers, specifically customized for HTTP, RTSP based streaming are ideally suited for developing quick I.P. based streaming systems.

The system targets Remote Monitoring, live event broadcasting, home/office monitoring, archiving of the video in a centralized server and related applications.

It is also ubiquitous-ready product to be used in the T-Engine compatible ubiquitous devices. It is still under enhancement to support more and more number of client devices.

V2oIP on T-Engine

Video & Voice over Internet Protocol on T-Engine is ready to deploy solution in ubiquitous devices those require voice communication functionality. Video support is under development and shall be released shortly. This Framework provides SUA Toolkit, RTP/RTCP Toolkit & CODEC on T-Engine to develop innovative products for ubiquitous and IP telephony domain. It can be utilized to develop components like Set top box, media Gateways, Soft-phones, Soft-switches, Interactive voice response & Push to Talk solutions.

SUA Toolkit is a powerful and versatile development toolkit designed to fulfill the development requirements of SIP User Agent based systems. This complies with the IETF SIP specifications RFC-3261. The Toolkit is a high performance SIP over T-Engine and provides API layers for optimal call control mechanism.

RTP/RTCP (Real-Time Transport Protocol/Real-Time Transport Control Protocol) Toolkit over T-Engine is designed to fulfill the requirements of media transmission over Internet Protocol. The Toolkit provides media transport functionalities and can be seamlessly integrated with small embedded platforms to densely populated processing environments. It can be used with SIP, H323 or other protocols to transport audio, video and real time text data over network. This Toolkit is in compliance with IETF RFC-1889.

Ubiquitous Applications

TRON Technology

"TRON (The Real-time Operating system Nucleus) is a project started by Dr. Ken Sakamura of the University of Tokyo in 1984 .

Work is now going ahead on various subprojects, including five fundamental subprojects and five application subprojects. The fundamental subprojects study each component of computer systems required for the construction of HFDS. They include the TRON-specification CHIP (VLSI microprocessor architecture), ITRON (real-time multi-task OS specifications for embedded control applications), BTRON (an architecture centering on OS specifications for use in personal computers and workstations), CTRON (OS interface specifications for communication and information processing), MTRON (an attached operating system architecture, still in the basic research stage) and eTRON along with T-engine which defines the open platform for ubiquitous device development with RAPID ACTION DEVELOPMENT APPROACH.

I.A.P. Company is a member company of the T-engine forum listed on the following URL: http://www.t-engine.org/English/member.html. IAPs R&D division is focused for Japanese Market specific Researches and Development, using Open Source TRON Technologies like, BTRON (Desktop OS), ITRON (Ubiquitous Device RTOS), eTRON (Secured Network Architecture), T-Engine (Open Ubiquitous Platform), uID (Ubiquitous ID, based on RFID).

  uID for Intelligent Society
   
  An individual with a Ubiquitous technology enabled device could use it as an authenticating device, an identity; he could use it to control all the devices in his home. He could check the status of the food in his refrigerator in conjunction with expert system. Ubiquitous technologies are opposite of virtual reality in which a user interacts with reality in real time, anywhere, anytime.

3GPP and 3GPP2
The 3GPP architecture evolved from the already-existing GPRS network. It can be viewed as IP-based multimedia enhancements to 2G networks. However, 3GPP2 has created a new architecture (there was no existing packet packet data service) for the 2G and 3G CDMA air interfaces
Basic Design Philosophy of 3GPP2
Leverage existing globally-accepted IETF protocols whenever possible e.g., mobile IP (for mobility), IPSec (for e2e security), AAA (authentication, authorization and accounting for network access).

Some advantages are –
- Interoperability/roaming with existing IP networks.
- Easy deployment of new services.
- Well understood standards.

Comparison Between 3GPP and 3GPP2
3GPP
  3GPP2
3GPP uses GGSN, SGSN
nodes.
  3GPP2 uses mobile IP and PSDN as FA/HA .
3GPP does not allow
heterogeneous access.
  It allows heterogeneous access.
The HLR is likely to be used
by the SGSN for authenticating
data users. Thus, access and
data network authentication are
integrated.
  The PDSN uses an AAA infrastructure to authenticate data
users. Access and data network authentication are separate.
The 3GPP model has a SIP-like
functionality in the 3 types of
Call State Control Functions
(CSCF).
  Though the specification is yet to be published, 3GPP2 has decided to use SIP.In the 3GPP2 model, location service is more of a database i.e., access-independent.

Location service in the 3GPP
model is tied closely to the
access.
GTP is used to provide link-
layer mobility.

 

Link layer mobility in the 3GPP2 world is viewed as a direct extension of mobile IP.

 
Important Points
Though the 3GPP and 3GPP2 NAM differ, active harmonization initiatives such as MWIF are cause for optimism.
Remember that harmonization on the access is also being tried for (or else dual mode devices would be necessary).
SIP seems to be the choice for session initiation over H.323 and other protocols.
There are strong reasons for using IPv6 in 3G networks. But, all commercial 3G networks till date use IPv4 (since it is easier to deploy).
