摘要：In recent years, the mobile devices are becoming more favorable due to small size, portability, etc. Despite of these improvements on mobile devices such as laptops, smart phones, etc the battery is always a limiting factor. Cyber foraging is a technique in which the small mobile devices offload the resource consuming data or applications from resource constrained mobile devices to resourceful devices. In the mobile devices CPU depletes resources very rapidly. In this paper, we found out that and show that CPU utilization has decreased and performance has increased for the mobile devices by utilizing cyber foraging approach. Several issues of data offloading such as performance of device, privacy of data from cloud vendor, storage on cloud have been tackled. A cloudlet defined as a new framework in architecture to represent middle-tier in 3-tier hierarchy¨C(mobile device-cloudlet-cloud).Comparative study has been done between varied mobile and non mobile devices and results show that non mobile devices give greater performance. Also comparison between 3G and Wi-Fi has been done and found out that 3G gives poor performance as compared to Wi-Fi. Moreover, experiments have been performed by statically offloading different sized applications from resource constrained mobile devices to resourceful cloud front end in our framework and results show that it is better to offload huge sized apps on cloud as CPU utilization is high when executed on mobile devices as compared to cloud and thus the storage issue of device has been tackled off. Finally the results conclude that the proposed 3-tier framework of cyber foraging technique reduces the overheads of latency, CPU Utilization and thereby improves the mobile device performance.
