Mitigating control-channel jamming attacks in multi-channel ad hoc networks
We address the problem of control-channel jamming attacks in multi-channel ad hoc networks. Deviating from the traditional view that sees jamming attacks as a physical-layer vulne...

Fair Randomized Antenna Allocation in Asynchronous MIMO Multi-Hop Networks
Abstract—Previous work has shown that CSMA-based protocols such as the IEEE 802.11 can yield flow starvation in multihop wireless networks. While prior protocol designs alleviat...
