Optimizing Random Access for Information Freshness in Spatially Distributed Wireless Networks
We analyze Age of Information (AoI) in wireless networks where nodes use a spatially adaptive random access scheme to send status updates to a central base station. We show that the set of achievable AoI in this setting is convex, and design policies to minimize weighted sum, min-max, and …

Age of information for broadcast and collection in spatially distributed wireless networks
We consider a wireless network with a base station broadcasting and collecting timesensitive data to and from spatially distributed nodes in the presence of wireless interference. The Age of Information (AoI) is the time that has elapsed since the mostrecently delivered packet was generated, and …

Distributed coordination in network information theory
Constructing a large-scale wireless data network is spectacularly expensive. It is therefore important to understand how to efficiently utilize the physical infrastructure and available battery power, which are expensive system resources. Unfortunately, we currently understand very little about …

Distributed medium access control for an enhanced physical-link layer interface
Current wireless network architecture equips data link layer with binary transmission/idling options and gives the control of choosing other communication parameters to the physical layer. Such a network architecture is inefficient in distributed wireless networks where user coordination can be …
