In this paper we investigate the handover cost and mobility-safety of content streams. Content streams are continuous flows of information from one node in a distributed network to another. The flows are established using publish/subscribe primitives and content-based routing of information. We examine two useful properties for mobility-aware content routing systems, namely completeness and mobility-safety. Then we determine the topology update cost for three interesting topologies, a number of optimizations, and show that if completeness cannot be assumed the signalling cost is considerably higher and content-based flooding needs to be used. We present simulation results for subscriber mobility for the investigated protocols. Both theoretical and experimental results show that rendezvous-points may be used to significantly reduce the signalling cost of handovers.
