A multiplicative weight perturbation scheme for distributed beamforming in wireless relay networks with 1-bit feedback
This paper focuses on perturbation-based distributed beamforming with 1-bit feedback for wireless amplify-and-forward relay networks. We propose to use multiplicative perturbation...

Adaptive Multi-Copy Routing for Intermittently Connected Mobile Ad Hoc Networks
— Intermittently Connected Mobile Ad Hoc Networks (ICMANs) are mobile networks in which complete source-todestination paths do not exist most of the time because of their sparse ...

Connectivity-Aware Network Maintenance via Relays Deployment
— In this paper, we address the network maintenance problem, in which we aim to maximize the lifetime of a sensor network by adding a set of relays to it. The network lifetime is...
