Is CSMA/CA really efficient against interference in a wireless control system? An experimental answer
The deployment of a wireless control system must cope with a number of effects usually negligible in a wired scenario. To this aim, an experimental analysis on suitable prototypes...

General Network Lifetime and Cost Models for Evaluating Sensor Network Deployment Strategies
In multihop wireless sensor networks that are often characterized by many-to-one (convergecast) traffic patterns, problems related to energy imbalance among sensors often appear. S...
