Attack-Resistant Location Estimation in Sensor Networks
- In Proceedings of the International Conference on Information Processing in Sensor Networks (IPSN
, 2005
"... Abstract — Many sensor network applications require sensors ’ locations to function correctly. Despite the recent advances, location discovery for sensor networks in hostile environments has been mostly overlooked. Most of the existing localization protocols for sensor networks are vulnerable in hos ..."

in hostile environments. The security of location discovery can certainly be enhanced by authentication. However, the possible node compromises and the fact that location determination uses certain physical features (e.g., received signal strength) of radio signals make authentication not as effective
Radio-telepathy: extracting a secret key from an unauthenticated wireless channel
- In MobiCom ’08
, 2008
"... Securing communications requires the establishment of cryptographic keys, which is challenging in mobile scenarios where a key management infrastructure is not always present. In this paper, we present a protocol that allows two users to establish a common cryptographic key by exploiting special pro ..."

bits from correlated stochastic processes. The resulting protocol resists cryptanalysis by an eavesdropping adversary and a spoofing attack by an active adversary without requiring an authenticated channel, as is typically assumed in prior information-theoretic key establishment schemes. We evaluate
Full-Duplex Wireless Communications Using Off-The-Shelf Radios: Feasibility and First Results
"... Abstract—We study full-duplex wireless communication systems where same band simultaneous bidirectional communication is achieved via cancellation of the self-interfering signal. Using offthe-shelf MIMO radios, we present experimental results that characterize the suppression performance of three se ..."

Full Duplex Radios
"... This paper presents the design and implementation of the first inband full duplex WiFi radios that can simultaneously transmit and receive on the same channel using standard WiFi 802.11ac PHYs and achieves close to the theoretical doubling of throughput in all practical deployment scenarios. Our des ..."

to the received signal. We prototype our design by building our own analog circuit boards and integrating them with a fully WiFi-PHY compatible software radio implementation. We show experimentally that our design works robustly in noisy indoor environments, and provides close to the expected theoretical doubling
Experimental evaluation of a nested microphone array with adaptive noise cancellers
- IEEE Trans. Instrum. Meas
, 2004
"... Abstract—This paper proposes a near-field broadband adap-tive beamforming scheme for intelligent computer telephony and teleconferencing applications, namely the nested microphone array with adaptive noise canceller (NMA-ANC). The NMA-ANC scheme incorporates an harmonically nested array with a nonun ..."

Practical, Real-time, Full Duplex Wireless
"... Co-primary authors This paper presents a full duplex radio design using signal inversion and adaptive cancellation. Signal inversion uses a simple design based on a balanced/unbalanced (Balun) transformer. This new design, unlike prior work, supports wideband and high power systems. In theory, this ..."

Wireless device identification with radiometric signatures
- in Proceedings of the 14th ACM international conference on mobile computing and networking, ser. MobiCom ’08
"... We design, implement, and evaluate a technique to identify the source network interface card (NIC) of an IEEE 802.11 frame through passive radio-frequency analysis. This technique, called PARADIS, leverages minute imperfections of transmitter hardware that are acquired at manufacture and are present ..."
