Abstract
In a decentralised distributed VR system like VEplatform, processes are used to represent the entities of a virtual world. These processes are scattered arbitrarily on a heterogeneous network of computers. Even a viewer is regarded as an entity and is thus represented by a process. Data is transmitted from the ordinary entities to the viewers and updated regularly. Since the demand of network resources is particularly high the system becomes very slow when the processes are badly located. In many cases, it would be appropriate to relocate processes to other hosts while the system is running. This implies that the process is relocated to another host without affecting the (possible changing) state of the data. Moreover there has to be a criterion that gives an optimal host for a particular process, taking into account the communication needs between the processes. This paper proposes such a criterion and evaluates the resulting distribution.
