Optimizing Caching Policy at Base Stations by Exploiting User Preference and Spatial Locality

Most prior works of proactive caching at wireless edge optimize caching policies under the following assumptions: the preference of each user is identical to content popularity, all users request contents with the same active level and at uniformly-distributed locations. In this paper, we investigate what happens without these assumptions. To this end, we establish a framework to optimize cachi...

Localized Temporal Reasoning Using Subgoalsand

We are concerned with temporal reasoning problems where there is uncertainty about the order in which events occur. The task of temporal reasoning is to derive an event sequence consistent with a given set of ordering constraints to achieve a goal. Previous research shows that the associated decision problems are hard even for very restricted cases. In this paper, we investigate locality in eve...

Methods for Creating and Exploiting Data Locality

The Case for Exploiting Packet Loss Locality in Multicast Loss Recovery

This paper makes the case for exploiting packet loss locality in the loss recovery of reliable multicast protocols, such as SRM [4]. We claim that packet loss locality in IP multicast transmissions can be exploited by simple caching schemes. In such schemes, receivers cache information about the recovery of recently recovered packets and use this information to expedite the recovery of subseque...

Exploiting Computational Locality in Global Value Histories

BODINE, JILL THERESE. Exploiting Computational Locality in Global Value Histories. (Under the direction of Thomas M. Conte.) Value prediction is a speculative technique to break true data dependencies by using history to predict values before they are computed. Previous research focused on exploiting two types of value locality (computation-based and context-based) in the local value history, w...

Exploiting Cache in Multimedia

The paper explores cache strategies for multimedia. Although many architectural improvements have been designed for multimedia, the cache structure and the standard caching policies of general-purpose processors exhibit poor performance in exploiting the 2D spatial locality typical of programs handling and processing images. In this paper we propose a novel caching approach suitably tailored to...
