A tight bound on the number of mobile servers to guarantee transferability among dominating configurations

Satoshi Fujita
2010 Discrete Applied Mathematics  
We model those mobile servers as a subset of nodes, and assume that a user can receive the service if at least one adjacent node (including itself) plays the role of a server; i.e., we assume that the  ...  In this paper, we propose a new framework to provide continuous services to users by a collection of mobile servers distributed over an interconnection network.  ...  Acknowledgement The author is deeply grateful to anonymous reviewers for their kind suggestions and critical comments in improving the quality and the readability of the paper.  ...
