Toward local overlay-based Mobile Clouds

Mobile devices are evolving into powerful systems due to recent advances in their communication, storage and computation technologies. They are posed to play a key role in providing a rich collaborative computing platform for various applications. Most of these devices have the ability to form a mobile cloud among themselves without relying on an existing infrastructure making them useful in scenarios in which access to infrastructure may not be feasible or expensive. In this paper we present a collaborative computing mobile cloud that enables a group of mobile devices to form an ad-hoc network and advertise their capabilities as cloud services. The mobile cloud capitalizes on locality through the use of a GPS-based hashing technique and a hybrid routing algorithm that combines reliable flooding with Distributed Hash Tables (DHT) to find the closest node(s) that have the desired capabilities for task execution. We evaluate the performance of our proposed mobile cloud through extensive simulations and our results show the feasibility of our proposed platform.
