  abstract     = {{The dynamic page migration problem citedynamic-page-migration is defined in <br>a distributed network of $n$ mobile nodes sharing one indivisible memory page <br>of size $D$. During runtime, the nodes can both access a unit of data from<br>the page and move with a constant speed, thus changing the costs of communication.<br>The problem is to compute <em> online</em> a schedule of page movements<br>to minimize the total communication cost.<br><br>In this paper we construct and analyze the first deterministic algorithm for this problem. <br>We prove that it achieves an (up to a constant factor) optimal competitive ratio <br>$O(n cdot sqrtD)$. We show that the randomization of this algorithm <br>improves this ratio to $O(sqrtD cdot log n)$ (against an oblivious adversary). <br>This substantially improves an $O(n cdot sqrtD)$ upper bound from citedynamic-page-migration.<br>We also give an almost matching lower bound of $Omega(sqrtD cdot sqrtlog n)$ for this problem.}},
