Applying static network protocols to dynamic networks

This paper addresses the problem of how to adapt an algorithm designed for fixed topology networks to produce the intended results, when run in a network whose topology changes dynamically, in spite of encountering topological changes during its execution. We present a simple and unified procedure, called a reset procedure, which, when combined with the static algorithm, achieves this adaptation. The communication and time complexities of the reset procedure, per topological change, are independent of the number of topological changes and are linearly bounded by the size of the subset of the network which participates in the algorithm.
