Femtolet: A novel fifth generation network device for green mobile cloud computing

For the first time, this paper proposes a new network device denoted as ‘Femtolet’ for fifth generation mobile network to provide communication and computation offloading facilities simultaneously at low power and low latency. The features of two separate devices femtocell base station and cloudlet are combined into a single network device denoted as Femtolet to provide the services of femtocell along with a cloud environment at low power and low latency. The architecture and working principle of the proposed device Femtolet are discussed with its power consumption model and latency. Mathematical analyses present that using Femtolet instead of the existing femtocell plus cloudlet and Small Cell cloud-enhanced e-node B architectures, power consumption can be reduced by approximately 17% and 11% respectively. Mathematical analyses also show that the proposed device Femtolet can reduce the latency by approximately 20% and 13% than the existing femtocell plus cloudlet and Small Cell cloud-enhanced e-node B architectures respectively. The proposed working model of Femtolet is simulated using Qualnet7 and its performance is analyzed with respect to average delay, average jitter, energy consumption in transmit and received modes, carried load, throughput, offloading time and offloading power.
