Abstract

We consider two fundamental problems of minimizing energy consumption and maximizing the lifetime of a given communication request in multi-hop wireless networks that use configurable antennas and have limited energy resources. We provide a globally optimal solution to this problem by developing a general optimization model that can apply to many antenna models including highly and moderately directional antenna types. Our numerical experiments validate our formulations and the obtained results reveal the performance behavior as a function of antenna and multicast configurations for some network examples.
