The objective of PIKS is to provide a wide range of information and services to people who are mobile within a defined organizational area. PIKS builds upon the future pervasive availability of small, simple low-end PDA-type devices that will be carried by everyone and used for a variety of purposes.] Purpose:[To be presented at the LRSG tutorial session.] Notice:This document has been prepared to assist the IEEE P802.15.

3. doc.: IEEE 802.15-00/361r0 Submission November, 00 Boaz Carmeli, IBM HRLSlide 3 Outline Organizational Information Delivery in the Pervasive World The Network Level –Requirements –Alternatives –Proposed solution Summary

4. doc.: IEEE 802.15-00/361r0 Submission November, 00 Boaz Carmeli, IBM HRLSlide 4 Organizational Information Delivery in the Pervasive World Organizational Information delivery –Organization boundaries –Personalized and location based information The Pervasive World –Used by the masses –Mobile users – Seamless roaming –Many devices; Many types The Pervasive Device –Limited resources –Small screen –Simple to operate and use

5. doc.: IEEE 802.15-00/361r0 Submission November, 00 Boaz Carmeli, IBM HRLSlide 5 Requirements from a Network Minimal power consumption Low cost Small size Fast synchronization and response time Distributed network - client server architecture Serve many (anonymous) users Zero configuration Transparent roaming Location awareness

6. doc.: IEEE 802.15-00/361r0 Submission November, 00 Boaz Carmeli, IBM HRLSlide 6 Network Alternatives ( Pros & Cons) 802.11 802.15.1 Power ConsumptionVery highStill too high CostVery highCan be suitable, if target reached Synchronization TimeGoodPoor, for mobile users Distributed NetworkExistVery Complicated to achieve Serve many usersReasonable (Random Access) Limited (TDMA) Configuration complexity Very highNot clear yet – Especially for the needed topology

7. doc.: IEEE 802.15-00/361r0 Submission November, 00 Boaz Carmeli, IBM HRLSlide 7 Proposed Solution 802.11 light version to better support: –Low cost –Low power consumption –Small size –Zero configuration OR Modification to 802.15.1 to better support: –Distributed network –Many users –Faster synchronization time –Seamless roaming Inherent location awareness capability is very important

8. doc.: IEEE 802.15-00/361r0 Submission November, 00 Boaz Carmeli, IBM HRLSlide 8 Summary Information delivery to pervasive devices is a hot issue No suitable solution exists To enable adoption by masses, solution must be very easy to maintain: –Infrequent battery replacement or recharging (if ever) –Zero configuration –Ultra low cost Small screen size leads to modest bandwidth requirements (19200 bps per user is more than enough)
