Diversify sensor nodes to improve resilience against node compromise
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)...

Bounds for the capacity of wireless multihop networks imposed by topology and demand
Existing work on the capacity of wireless networks predominantly considers homogeneous random networks with random work load. The most relevant bounds on the network capacity, e.g...

Network Coding Does Not Change the Multicast throughput Order of Wireless Ad Hoc Networks
We demonstrate that the gain attained by network coding (NC) on the multicast capacity of random wireless ad hoc networks is bounded by a constant factor. We consider a network wit...

Joint Physical Layer Coding and Network Coding for Bi-Directional Relaying
Abstract-- We consider the problem of two transmitters wishing to exchange information through a relay in the middle. The channels between the transmitters and the relay are assume...
