Directional Versus Omnidirectional Antennas for Energy Consumption and k-Connectivity of Networks of Sensors
A network is k-connected if it remains connected after the removal of any k - 1 of its nodes. Assume that n sensors, modeled here as (omni)directional antennas, are dropped random...

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...
