A salient feature of sensor networks is that the network elements are very tightly coupled with the physical environment. The resource requirements change dynamically as the environment evolves in space and time. Sustainability is defined as an attribute of wireless networks that describes their ability to maintain a continuous Quality of Service (QoS) for their client applications. The ability to move directly translates into. Controlled mobility has significant benefit for sensor network sustainability enhanced QoS. Mobility provides a level of control on the network topology.
