Comparison of replication strategies for content availability in C2P2 networks

Published: 09 May 2005 Publication History

Abstract

This study investigates alternative continuous media replication techniques and their impact on content availability in a mobile car-to-car peer-to-peer (C2P2) network of devices. Using aggregate availability latency as a metric, we compare a simple random replication mechanism with a family of techniques that compute the degree of replication for each title based on its popularity, i.e., frequency of access. We use a simulation study along with some supporting analytical analysis for this comparison. Obtained results demonstrate the following key lesson. When total storage capacity of the network is significantly larger than the clip repository size, a random replication technique is sufficient. Otherwise, there is a large parameter space where the frequency-based replication schemes provide superior performance.
