Introducing mobile data sinks into wireless sensor networks (WSNs) improves the energy efficiency and the network lifetime, and is demanded for many application scenarios, such a...
We develop a theory for deciding, for any routing metric and any network, whether the messages in this network can be routed along paths whose metric values are maximum. In order ...
Routing has been the main challenge for ad hoc networks due to dynamic topology as well as resource constraints. Completely GPS free as well as GPS scarce positioning systems for ...
Experiments with wireless sensor networks have shown that unidirectional communication links are quite common. What is even more, they have also shown that the range of a unidirect...
