Our spanner has size $O(n / ϵ^{d-1})$ and maximum degree $O(\log ^{d} n)$. The main advantage of our spanner is that it can be maintained efficiently as the points move: Assuming that the trajectories of the points can be described by bounded-degree polynomials, the number of topological changes to the spanner is $O(n^{2} / ε^{d-1})$, and using a supporting data structure of size $O(n \log^{d} n)$, we can handle events in time $O(\log ^{d+1} n)$. Moreover, the spanner can be updated in time $O(\log n)$ if the flight plan of a point changes. This is the first kinetic spanner for points in $\Bbb R^{d}$ whose performance does not depend on the spread of the point set. rv:
