1 Radio Resource Management WINLAB IAB Meeting October 29-30, 2001 Roy Yates 1
2 What is RRM? NETWORK Routing, Flow Control Radio Resource Management Efficient Wireless Access PHY Radio/Modem Technology 2
3 RRM Ancient History (pre 1996) hk1 BS k h k4 h 14 BS 1 h k5 h k2 h k3 h 15 h 16 Anytime Anywhere cellular voice service Each user needs an acceptable connection: Channel, Base station, Transmit Power 3
4 Cellular Wireless Today Optimized for Anytime/Anywhere voice Strict Network Control Licensed Bandwidth Limited Wireless Data Low to Moderate Rates kb/s kb/s High Cost per bit 10 kb/s, 10 cents/min = $1.30/MB 4
5 Cellular = Expensive Bits 1 cent/min = 13 cents/mb Fill an MP3 player Upload camera photos Sync laptop disk 30 MB 32 MB 50 MB $3.90 $4.16 $ cent/min voice is still 100x too high for data 5
6 Internet Access = Free Bits Internet: Applications and attitudes are based on free bits Fill an MP3 player: 30 MB = FREE To get a lot of bits, you wait more but not pay more Cellular access is a toll booth Radio bits need to be free 6
7 Infostations A system of sweet spots for free bits Maps and images Music, voic , news Small, separated cells Internet access Low power (~100 mw) Brief connections (~1 sec) Very high bit rate (~1 G bps) Simple infrastructure (LAN on a pole, IP access) Unlimited capacity for a flat rate? 7
8 Free Bits NSF ITR Multi-university Project WINLAB, Princeton, NJIT Research Areas Radio Channel Modeling Transceiver Design Radio Resource Management Algorithm Development Testbed 8
9 RRM Research at WINLAB About 15 student projects Investigators Evans, Frenkiel, Gajic, Mandayam, Mau, Raychaudhuri, Rose, Spasojevic, Yates Range of Systems: 3G cellular, infostations, ad hoc data networks 9
10 Common Theme Methods for Efficient Transmission Opportunistic Transmission Transmit when/where the channel is good Exploit sweet spots, delay insensitivity Conserve battery power Mechanisms for Distributed Control Power Control, Interference avoidance Utility functions to unify mixed objectives 10
11 15 RRM Projects 1. Interference Avoidance and Fading Channels 2. Interference Avoidance for Multiple Basestation Systems 3. Using Mobility for Delay-Tolerant Data Transmission in Ad-Hoc Networks 4. Energy and Delay Constrained Dynamic Transmission Control in Wireless Data Communications Systems 5. Access Control for Mixed Receivers, Integrated Voice/Data CDMA Systems 6. Pricing and Power Control for Joint Network-Centric and User-Centric Radio Resource Management 7. Routing in Ad Hoc Networks 8. Service Outage Based Adaptive Transmission in Fading Channels 9. Discrete Adaptive Transmission for Fading Channels 10. Downlink Interference Analysis 11. Multicast Transmission in the Downlink of Wireless System 12. Effects of Channel Models on Performance of MobileAd Hoc Networks 13. Power Control in Ad Hoc Networks Using Hello and Data Packets 14. OFDM Based Multiple Access Systems 15. Dynamic Nash Games for Power Control in 3-G Wireless CDMA Networks 11
12 Access Control Sharing for Heterogeneous Services Access Control for Mixed Receivers, Integrated Voice/Data CDMA Narayan Mandayam and Cristina Comaniciu Pricing and Power Control for Joint Network-Centric and User- Centric Radio Resource Management Narayan Mandayam, Siun-Chuon Mau and Nan Feng Downlink Interference Analysis Roy Yates and Mehmet Kemal Karakayali Multicast Transmission in the Downlink of Wireless System Roy Yates and Nanyan Jiang OFDM Based Multiple Access Systems Roy Yates and Rajnish Sinha Dynamic Nash Games for Power Control in 3-G Wireless CDMA Zoran Gajic and Sarah Koskie 12
13 Access Control Sharing for Heterogeneous Services Closely tied to receiver technology WCDMA, Multiuser Detection, OFDM Multiple Services Voice, Web, Video Utility Functions to unify mixed objectives Pricing Mechanisms to improve user s utilities 13
14 Adaptive Transmission Transmit When the Channel is Good Energy and Delay Constrained Dynamic Transmission Control in Wireless Data Communications Systems Narayan Mandayam and Henry Wang Service Outage Based Adaptive Transmission in Fading Channels Roy Yates and Jianghong Luo Discrete Adaptive Transmission for Fading Channels Roy Yates and Lang Lin Goal: Reduce the Energy per bit Increase power and rate as channel improves Turn the transmitter off if channel is bad. Result: Transmit in sweet spots Infostations 14
15 Interference Avoidance Transmit Where the Channel is Good Interference Avoidance and Fading Channels Christopher Rose and Dimitrie C. Popescu Interference Avoidance for Multiple Basestation Systems Christopher Rose and Otilia Popescu Where is in signal space! Depends on Interference and Radio Channels of Other Users Receivers find sweet spots in signal space Transmitters move to the sweet spots 15
16 Ad Hoc Wireless Networks Using Mobility for Delay-Tolerant Data Transmission in Ad-Hoc Networks Christopher Rose and Furuzan Atay Routing in Ad Hoc Networks Roy Yates and Ivana Maric Effects of Channel Models on Performance of MobileAd Hoc Networks Roy Yates and Wing Ho (Andy) Yuen Power Control in Ad Hoc Networks Using Hello and Data Packets Roy Yates and Wing Ho (Andy) Yuen Theme: Disseminate data efficiently among peers Users in sweet spots assist others 16
17 Overlapping Research Areas Infostations Free Bits Unlicensed Band Pricing Power Control Ad Hoc Networks Access Control Adaptive Transmission Interference Avoidance 17
