MotionCast: on the capacity and delay tradeoffs
In this paper, we define multicast for ad hoc network through nodes' mobility as MotionCast, and study the capacity and delay tradeoffs for it. Assuming nodes move according ...

Lattices that admit logarithmic worst-case to average-case connection factors
We demonstrate an average-case problem that is as hard as finding (n)-approximate shortest vectors in certain n-dimensional lattices in the worst case, where (n) = O( log n). The...

Sybilproof transitive trust protocols
We study protocols to enable one user (the principal) to make potentially profitable but risky interactions with another user (the agent), in the absence of direct trust between ...

Monotonic solution concepts in coevolution
Assume a coevolutionary algorithm capable of storing and utilizing all phenotypes discovered during its operation, for as long as it operates on a problem; that is, assume an algo...

Multicast time maximization in energy constrained wireless networks
We consider the problem of maximizing the lifetime of a given multicast connection in a wireless network of energyconstrained (e.g. battery-operated) nodes, by choosing ideal tran...
