Sample research projects

1. Physical-space security: (i) introduced Physical-space security - a paradigm that fundamentally limits the

knowledge of existence of information from the eavesdroppers at a spatial level, without relying on

computational hardness. (ii) proposed an architecture that uses beamforming across multiple access points in

a wireless LAN in a cooperative manner to achieve security against eavesdropping.

2. Feedback caching in wireless networks: (i) established the existence of redundancy in tra c traversing

smartphones through cellular and WLAN links. (ii) proposed a byte-level caching solution wherein the mobile

device intelligently advertises what it perceives to be important portions of its cache that the base-station

then uses for redundancy elimination.

3. Practical smart antenna link solutions: (i) proposed a Light-weight Spatial Reuse algorithm that

leverages coordinated beamforming across access points equipped with smart antennas in a wireless LAN. (ii)

new solution that uses signal power measurements which are easily available on o -the-shelf wireless clients to

achieve beamforming, along with link scheduling.

4. Cooperative multi-hop routing: (i) proposed a new multi-hop cooperative routing protocol that

signi cantly improves the scalability of multi-hop ows in a wireless network using cooperative transmissions

for adaptive range and rate increase. (ii) developed algorithms for deciding the number of cooperating

transmitters for each link; and the cooperation strategy used by the transmitters in an adaptive manner.
