We argue that no new potential extra packet may appear if GU does not transmit a packet from this input port. In this case, the potential extra packet appearing in a crosspoint queue of OPT must have already been potential extra at the ...
Consider a sensor s that is at position x and performs a Look at time t1 and the corresponding Move to the left at time ... If s performs a Look after time t1, then it can see s in its visibility range and therefore would not perform a ...

These are the proceedings of SIROCCO 2009: the 16th annual Colloquium on Structure, Information, Communication, and Complexity. SIROCCO is devoted to the study of the interplay and trade-offs between the efficiency of decentralized ...
The Colloquium on Structure, Information, Communication, and Complexity (SIROCCO) is devoted to the study of communication and knowledge in multiprocessor systems from both the qualitative and quantitative viewpoints.
the point-to-point communication model used in this paper (It is easy to show at least Ω(nlogK) bits are needed.). ... In [1], a lower bound of Ω(K/n4) on its communication complexity is proved for randomized algorithms.
2.1 Communication Complexity A private-coin communication protocol for computing a function f : X×Y→Z is a binary tree with the following generic structure. Each node in the protocol is owned either by Alice or by Bob.
... i.e., the relationships between information and efficiency in decentralized computing. ... of rings or grids to arbitrary graphs, turns out to have major impacts on complexity and computational feasibility of communication systems.
2.5 Two-Party Communication Complexity Given two vectors x, y∈ {0,1}s, we say the vectors are not disjoint, and write DISJ(x, y) = FALSE, if there exists an index i ∈ [s] such that xi = yi = 1. Otherwise, the vectors are disjoint, ...
In analyzing the structure of such a period, we show that the two messages to its single non-one-entry come from different directions, and that both contain bit 1. ... The linear-array problem in communication complexity re- solved.
We prove the existence/correctness/complexity of such protocols by induction on h. For h = 2 we use the two-round protocol of Proposition8. For the general case, first note that if the distance between two nodes is finite and strictly ...
Note that Ben-Zvi and Moses [4] modeled communication by time via explicitly sending a virtual NULL-message instead of a real one. Regarding the connection of action models and the synchronous model, we assume that a single action model ...
