Abstract— Discrete power allocation strategies for amplifyand-forward cooperative networks are proposed based on selective relaying methods. The goal of power allocation is to ma...
Power allocation strategies are devised to maximize the network lifetime of amplify-and-forward (AF) cooperative networks in this work. We consider the scenario where one source an...
— Extending lifetime of battery-operated devices is a key design issue that allows uninterrupted information exchange among distributed nodes in wireless networks. Cooperative co...

— We address a lifetime maximization problem for a single-hop wireless sensor network where multiple sensors encode and communicate their measurements of a Gaussian random source...
Wireless sensor networks hold the potential to open new domains to distributed data acquisition. However, such networks are prone to premature failure because some nodes deplete t...
