Predictive power control and multiple-description coding for wireless sensor networks
We study state estimation via wireless sensor networks over fading channels affected by random packet loss. In the configuration examined, the sensors send their measurements to ...

RBP: robust broadcast propagation in wireless networks
Varying interference levels make broadcasting an unreliable operation in low-power wireless networks. Many routing and resource discovery protocols depend on flooding (repeated pe...
