Towards realizable, low-cost broadcast systems for dynamic environments
TLDR
In this paper, popular broadcast scheduling approaches are tested from an implementation cost aspect, and the results render them only conditionally realizable, and a new, cost-effective, adaptivity oriented schedule constructor is proposed as a realistic, minimal-cost solution.Abstract:
A main design issue in a wireless data broadcasting system is to choose between push-based and pull-based logic: The former is used as a low-cost solution, while the latter is preferred when performance is of utmost importance. Therefore, the most significant advantage of a push system is the minimal cost. This fact implies that hardware limitations do exist in the case of push systems. As a consequence, every related proposed algorithm should primarily be cost-effective. This attribute, however, has been overlooked in related research. In this paper, popular broadcast scheduling approaches are tested from an implementation cost aspect, and the results render them only conditionally realizable. Moreover, a new, cost-effective, adaptivity oriented schedule constructor is proposed as a realistic, minimal-cost solution.read more

Broadcast disks: data management for asymmetric communication environments
TL;DR: This work describes a new technique called "Broadcast Disks" for structuring the broadcast in a way that provides improved performance for non-uniformly accessed data and examines several "pure" cache management policies and develops and measure implementable approximations to these policies.
