We describe a method to maintain an acceptable quality for video transported over wireless networks under timevarying conditions. We use a transcoder to modify the resilience of t...

—In this paper, we present a two-pass intra-refresh transcoder for on-the-fly enhancing error resilience of a compressed video in a three-tier streaming system. Furthermore, we c...
In this paper, we propose an "in-network" diversity combining scheme for image transport over wireless sensor networks. We consider a wireless sensor network with both w...
We present a new protocol for routing in multi-radio, multi-hop wireless networks. Our protocol, Multi-Radio Link-Quality Source Routing, is designed for wireless networks with st...
A great challenge in securing sensor networks is that sensor nodes can be physically compromised. Once a node is compromised, attackers can retrieve secret information (e.g. keys)...
