Classes of Delay-Independent Multimessage Multicast Networks under the Generalized Model
In a network, a node is said to incur a delay if its encoding of each transmitted symbol involves only its received symbols obtained before the time slot in which the transmitted symbol is sent (hence the transmitted symbol sent in a time slot cannot depend on the received symbol obtained in the same time slot). A node is said to incur no delay if its received symbol obtained in a time slot is ...
متن کاملStrong Converse Theorems for Multimessage Networks with Tight Cut-Set Bound
This paper proves the strong converse for any discrete memoryless network (DMN) with tight cut-set bound, i.e., whose cut-set bound is achievable. Our result implies that for any DMN with tight cut-set bound and any fixed rate tuple that resides outside the capacity region, the average error probabilities of any sequence of length-n codes operated at the rate tuple must tend to 1 as n grows. Th...
متن کاملDelay Bounds and Scalability for Overlay Multicast
A large number of peer-to-peer streaming systems has been proposed and deployed in recent years. Yet, there is no clear understanding of how these systems scale and how multi-path and multihop transmission, properties of all recent systems, affect the quality experienced by the peers. In this paper we present an analytical study that considers the relationship between delay and loss for general...

متن کاملQuantum Complexity Bounds for Independent Set Problems
We present quantum complexity lower and upper bounds for independent set problems in graphs. In particular, we give quantum algorithms for computing a maximal and a maximum independent set in a graph. We present applications of these algorithms for some graph problems. Our results improve the best classical complexity bounds for the corresponding problems.
