Abstract
Studies have shown the presence of considerable
amounts of redundancy in Internet traffic content. Recent
works are exploring possibilities for exploiting network traffic
redundancy, but these works invariably focus on fixed wireline
networks. Unlike wireline networks, wireless and mobile environments
exhibit unique challenges and opportunities in the
context of redundancy elimination.
In this work, we explore leveraging network traffic redundancy,
but exclusively focus on wireless and mobile environments.
We first analyze real Wi-Fi traces, and based on insights
obtained from the analysis, we propose Wireless Memory (WM),
a two-ended AP-client solution to effectively exploit traffic
redundancy for such environments. Trace-driven evaluation
results show that WM can help deliver significant throughput
improvement.
