Graphs with Bounded Induced Distance
In this work we introduce the class of graphs with bounded induced distance of order k, (BID(k) for short). A graph G belongs to BID(k) if the distance between any two nodes in ev...

Optimal Gossiping with Unit Size Messages in Known Topology Radio Networks
Gossiping is a communication primitive where each node of a network possesses a unique message that is to be communicated to all other nodes in the network. We study the gossiping ...

Information-Theoretic Bounds for Mobile Ad-hoc Networks Routing Protocols
Abstract. In this paper, we define the routing overhead as the amount of information needed to describe the changes in a network topology. We derive a universal lower bound on the...

The optimal sequence compression
This paper presents the optimal compression for sequences with undefined values. Let we have (N -m) undefined and m defined positions in the boolean sequence V of length N. The se...

Near-Optimal Conversion of Hardness into Pseudo-Randomness
Various efforts ([?, ?, ?]) have been made in recent years to derandomize probabilistic algorithms using the complexity theoretic assumption that there exists a problem in E = dti...
