Practical Implementation of Femtolet Based Peer-to-Peer Network

Energy and latency aware code offloading is a demanding research area for nowadays. In this paper, for the first time we have successfully implemented the prototype of femtolet for fifth generation mobile network. Mobile devices are registered under a femtolet. The femtolet provides voice call service as well as code offloading facilities to the mobile devices. A femtolet has coverage of 10–20 m. In a particular indoor zone, there may be a number of femtolets allocated. These femtolets communicate with each other and form a peer-to-peer network. When a mobile device has to execute a resource intensive application, it requests the femtolet. If the femtolet is unable to process the task, it asks its nearby peer that is either a femtolet or a cloudlet to offload it. If the nearby peer is also unable then forwards the request to the most powerful peer i.e. the remote cloud server. The remote cloud server further executes the task. The experimental analysis shows that the proposed offloading scheme reduces the energy and latency in code offloading by approximately 10–22% and 11–14% respectively than the existing cooperative offloading model.
