Sep 3 Fine-grained Channel Access in Wireless LAN Proposes FICA, a fine-grained channel access method for WLANs: new PHY architecture based on OFDM, frequency-domain contention, stations contend for OFDM subcarriers using PHY layer RTS/CTS. SIGCOMM '10 Dimitris fica.ppt
Sep 10 The Spaces Between Us: Setting and Maintaining Boundaries in Wireless Spectrum Access Proposes Ganache, a guardband configuration system; sets and adapts guardbands based on local topology and propagation conditions. MobiCom '10 Wei-Cheng ganache.pdf
Sep 17 Efficient Error Estimating Coding: Feasibility and Applications (BEST PAPER) Proposes new type of codes, Error Estimating Codes (EEC). EEC does not correct errors (unlike Error Correction Codes -- ECC) but enables the receiver to estimate the BER with lower redundancy and computational overhead than ECC. SIGCOMM '10 Jaemin EEC.pdf
Oct 1 Exploring Link Correlation for Efficient Flooding in Wireless Sensor Networks Proposes Collective Flooding (CF), a flooding technique exploiting link correlation and collective ACKs to achieve the same level of flooding reliability as state-of-the-art solutions with 30-50% lower number of packet transmissions and dissemination delay. NSDI '10 Iftekharul
Oct 8 Frequency-Aware Rate Adaptation and MAC Protocols Proposes FARA, a combined frequency-aware rate adaptation and MAC protocol. Computes per-frequency (OFDM subcarrier) SNR, adapts bitrate independently across frequencies, allocates each sender-receiver pair the frequencies that work best for that pair. MobiCom '09 Xiaohang
Oct 15 CSMA/CN: Carrier Sense Multiple Access with Collision Notification Since CSMA/CD (collision detection) is not feasible in wireless networks, the paper proposes CSMA/CN (colision notification), exploiting signal correlation. MobiCom '10 Dimitris
Oct 29 Distributed and Provably-Efficient Algorithms for Joint Channel-Assignment,
Scheduling and Routing in Multi-Channel Ad Hoc Wireless Networks
Develops online algorithms to jointly solve the channel-assignment, scheduling and routing problem. Shows the algorithms are provably efficient, i.e., even compared with the optimal centralized and offline algorithm, they can achieve a provable fraction of the maximum system capacity. ToN '09 Can
Nov 5 A Case for Adapting Channel Width in Wireless Networks Makes the case for systems that adapt channel width, proposes SampleWidth, a channel width adaptation algorithm for the base case of a sender-receiver pair. SIGCOMM '08 Wei-Cheng
Nov 19 Supporting Demanding Wireless Applications with Frequency-agile Radios Proposes Jello, an alternative (distributed) approach to CSMA that relies on frequency-agile radios. Addresses the spectrum fragmentation problem using two techniques: online spectrum defragmentation and non-contiguous access. NSDI '10 Xiaohang
Nov 26 NO MEETING - Thanksgiving
Dec 3 Learning to Share: Narrowband-Friendly Wideband Wireless Networks Proposes SWIFT, a system that allows high-throughput wideband nodes to coexist with unknown narrow-band devices (802.11, ZigBee), without sacrificing throughput and distance of wideband devices. SIGCOMM '08 Dawei
