Timing-Based Mutual Exclusion with Local Spinning,n, we consider both possibilities. For each of these possibilities, we present an algorithm with either Θ(1) or Θ(log log .) time complexity.

Lower Bounds for Oblivious Single-Packet End-to-End Communication,t headers of Ω(. . .) bits are required in every network, where . denotes the tree-width of the network. In planar networks, Ω(. .) bits are required. In particular, this latter lower bound closes the open problem by Adler and Fich in PODC ‘99 about the optimality of the . protocol in square meshes.作者: jeopardize 時(shí)間: 2025-3-23 17:00
