Adding Virtual Mobility to a Federated Testbed for Wireless Sensor Networks: a Proposal

In this document we present an initial design that accommodates ‘virtual mobility’ into testbeds for wireless sensor networks. The virtual mobility of physical, simulated or emulated nodes is treated in a uniform manner by embedding the nodes in a virtual space. The virtual space is formed by a simulation model and handles all the traffic from the nodes. The traffic of physical nodes is therefore intercepted and redirected to this model. We discuss the aspects of ‘virtual mobility’ and provide an initial design that supports ‘virtual mobility’ across a federated testbed for wireless sensor networks.
