We consider dynamic routing in multi-hop wireless networks with adversarial traffic. The model of wireless communication incorporates interferences caused by packets’ arrivals into the same node that overlap in time. We consider two classes of adversaries: balanced and unbalanced. We demonstrate that, for each routing algorithm and an unbalanced adversary, the algorithm is unstable against this adversary...
Reliability, security and stability of cloud services without sacrificing too much resources have become a desired feature in the area of workload management in clouds. The paper proposes and evaluates a lightweight framework for scheduling a workload which part could be unreliable. This unreliability could be caused by various types of failures or attacks. Our framework for robust workload scheduling...
We study broadcasting on multiple access channels by deterministic distributed protocols. Data arrivals are governed by an adversary. The power of the adversary is constrained by the average rate of data injection and a bound on the number of different packets that can be injected in one round. The injection rate is at most 1, which forbids the adversary from overloading the channel. We consider a...
