Cyber-foraging with Cloudlets for Low-latency applications over Fiber-Wireless Networks

Research summary:

With the emergence of Internet of Things, Tactile Internet, and 5G applications, major interest is currently given to the integration of centralized cloud computing and distributed edge computing infrastructures to deliver higher performance and reliability to the mobile users in accessing mobile cloud services.  To fulfill the ravenous demand for computational resources entangled with the crisp latency requirements of various computationally heavy applications related to augmented reality, cognitive assistance and context-aware computation, installation of cloudlets near access seems to be a very promising solution because of its support for wide geographical network distribution, low latency, mobility and heterogeneity.

In this research work, we proposed a hybrid cloudlet placement network architecture over existing passive optical access network infrastructures. Initially, we focused on static cloudlet network planning and placement, i.e., identification of optimal cloudlet placement locations over urban, suburban and rural deployment scenarios to provide guidance on the installation and maintenance costs and assess the percentage of incremental energy arising from the presence of cloudlets in the optical access. After this, we proposed analytical cost optimization framework that resolves the scalability issues arising from integer programming-based frameworks, thus providing a user-friendly closed form expression to achieve a first-hand estimation of the cloudlet deployment cost against any scenario.  We further proposed an economic and non-cooperative game theoretic model among multiple competitive cloudlets.  This model aims to maximize the utilities of all the competing cloudlets while achieving a fairness in the overall end-to-end system latency.

Project Duration: 2016 – 2020
