NASC: Network-Aware Source Coding for Wireless Broadcast Channels with Multiple Sources
In this paper, we present a network-aware source coding (NASC) approach for wireless broadcast channels with multiple sources. The proposed NSAC approach takes into account the in...

Constructing minimum-energy broadcast trees in wireless ad hoc networks
In this paper we assume that a multihop wireless network (also called a wireless ad hoc network) consists of nodes whose transmitting powers are finitely adjustable. We consider t...
