Paper Abstract:
|
Replication advocated as a means to ensure service availability in infrastructure-less networks. Numerous approaches to service replication have been proposed in the literature differing mostly in the criteria employed to determine when to replicate and which node to put a new service replica on. Virtually all of these approaches have been solely evaluated using simulations mostly based on rather simplistic mobility models, e.g., the random waypoint model. For one such approach, namely the service distribution protocol SDP, we investigate in this paper, how big the influence of these models is on the simulation results, in particular, whether it achieves comparable performance results with more realistic mobility models. We have chosen a variation of AGM proposed by Bittner et. al as the basis for the experiments. The results are very promising and confirm the results obtained with simpler mobility models for SDP. |
