Abstract

In this paper, we present a mixed-integer linear program (MILP) designed to optimize max-min path lifetime for multicasts in directional antenna equipped networks in the presence of interference. We then employ the MILP to perform a head-to-head comparison between directional transmission and directional reception. We also propose and analyze a new directional reception heuristic. Our results indicate that directional reception can match directional transmission when extending path lifetime, with lower complexity and employing routes that use much less cumulative power.
