摘要: We introduce a distributed algorithm for clock synchronization in sensor networks. Our assumes that nodes the network only know their immediate neighborhoods and an upper bound on network's diameter. Clock-synchronization messages are sent as part of communication-assumed to be reasonably frequent-that already takes place among nodes. The has gradient property [R. Fan, N. Lynch, Gradient synchronization, Distributed Computing 18 (2006) 255-266], achieving O(1) worst-case skew between logical clocks neighbors. algorithm's actions such no constant lower exists rate at which progress time, this reason 255-266; L. Meier, Thiele, Brief announcement: networks, in: Proceedings Twenty-Fourth Annual ACM Symposium Principles Computing, 2005, p. 238] forbids neighbors does not apply.
