Antenna orientation optimization for minimum-energy multicast tree construction in wireless ad hoc networks with directional ant
Energy conservation is a critical issue in wireless ad hoc networks since batteries are the only energy source to power the nodes. One major metric for energy conservation is to r...

Performance analysis of opportunistic broadcast for delay-tolerant wireless sensor networks
This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay–tolerant wireless sensor networks (DTWSN). T...
