An Erasure Code Based Wireless Distributed Storage System Implementation

Abstract

Wireless distributed storage systems can potentially relieve the burden of the wireless access point caused by the rapidly increasing mobile users and emergence of network services. Specifically, considering the concept of distributed system and user mobility, we demonstrate an erasure code based wireless distributed storage system (WDSS), which is well designed to handle storage capacity limitation, power limitation and data loss caused by the disconnection from wireless users. We realize efficient and reliable content sharing between mobile users, thus increasing wireless service response speed and reducing the pressure of data traffic on the wireless access point. The demonstration of the system consists of 3 components, a WDSS server, a wireless AP and the user application. Furthermore, both openWrt based Wi-Fi access and OpenAirInterface (OAI) based cellular access can be implemented by the wireless AP.
