On distributed scheduling in wireless networks exploiting broadcast and network coding

In this paper, we consider cross-layer optimization in wireless networks with wireless broadcast advantage, focusing on the problem of distributed scheduling of broadcast links. The wireless broadcast advantage is most useful in multicast scenarios. As such, we include network coding in our design to exploit the throughput gain brought in by network coding for multicasting. We derive a subgradient algorithm for joint rate control, network coding and scheduling, which however requires centralized link scheduling. Under the primary interference model, link scheduling problem is equivalent to a maximum weighted hypergraph matching problem that is NP-complete. To solve the scheduling problem distributedly, locally greedy and randomized approximation algorithms are proposed and shown to have bounded worst-case performance. With random network coding, we obtain a fully distributed cross-layer design. Numerical results show promising throughput gain using the proposed algorithms, and surprisingly, in some cases even with less complexity than cross-layer design without broadcast advantage

Miss Olympic Athlete? A Content Analysis of NBC’s Primetime Interviews During the 2016 Summer Olympic Games

The 2016 Summer Olympic Games in Rio de Janeiro has further exposed the difference in sports reporting between sexes. Creating social media controversy, viewers called out the sexist commentary directed towards women athletes emphasizing their relationship status, how many children they have, and male athlete accomplishments over the female’s athletic ability. This content analysis will dive deeper into NBC’s prime-time coverage of the twenty-third Olympiad, examining the sport and non-sport questions brought up during interviews with the male and female athletes. With reporters possessing more control over what is discussed on-air, when compared to live commentators, the goal of this analysis is to examine if a significant difference of sport-related themes remains between sexes, or if a few outliers are drawing disproportionate attention. No significant difference was found between questions asked during interviews with male and female athletes, however, there was a significant difference found between the mean number of non-sport questions posed by male reporters when compared to female reporters. Suggestions for future research are also explored
