PERM is the Practical End-host collaborative Residential Multihoming framework. 802.11 networks have spread rapidly in the residential area, and it is common for neighbors to receive signals from each other's home wireless networks. PERM allows residents to leverage such an opportunity to improve their last-mile Internet connectivity, at no additional cost, by pooling their Internet accesses together. PERM is practical in that it does not rely on support from the network infrastructure in terms of advanced naming scheme or proxy, the remote host in terms of new transport protocols, or the end-user in terms of explicit application feedback or configuration. Instead, PERM employs automated on-line analysis of the user's networking behaviors, and exploits the identified patterns to achieve high-performance scheduling at the flow level. PERM is also highly usable for normal residential users. It preserves a user's privacy and security, and mitigates the free-riding problem. We have implemented PERM for Linux clients and the open-source Linksys wireless router.
