Object Management in Regular Network Topologies

Abstract

So far we have been describing the OMP in arbitrary networks under a specific objective, namely the (monetary) cost optimization. Chapters 4 and 5 have clearly exposed certain models that are suited for stationary and mobile computing environments and shown how the performance is influenced by several parameters. There have been numerous studies in this area of DDBS on a variety of issues and it is beyond the scope of this book to deal with all of them. However, what has not been so far mentioned is on the performance quantification for regular or known topologies. Conducting performance studies on known topologies is always a natural interest to implementation specialists and researchers. In this chapter, we will present two specific examples on known topologies, i.e., (a). star networks and (b). multi-level generic tree networks. We use the parameters defined in Chapters 4 and 5 to analyze the performance and our objective remains the same namely, the minimization of the monetary cost involved in servicing the requests. However, it may be noted that the parameters influencing the performance may differ on different topologies as each case is a special case. Also, it depends on the underlying assumptions made.
