Center node: "investigating the cost of anonymity on dynamic networks"
  Abstract: In this paper we study the diculty of counting nodes in a synchronous dynamic network where nodes share the same identier, they communicate by using a broadcast with unlimited bandwidth and, at each synchronous round, network topology may change. To count in such setting, it has been shown that the presence of a leader is necessary. We focus on a particularly interesting subset of dynamic networks, namely Persistent Distance -G(PD)h, in which each node has a xed distance from the leader across rounds and such distance is at most h. In these networks the dynamic diameter D is at most 2h. We prove the number of rounds for counting inG(PD)2 is at least logarithmic with respect to the network sizejVj. Thanks to this result, we show that counting on any dynamic anonymous network with D constant w.r.t. jVj takes at least D+(log jVj) rounds where (log jVj) represents the additional cost to be payed for handling anonymity.
