  In recent years, enormous growth has been witnessed in the computational and
storage capabilities of mobile devices. However, much of this computational and
storage capabilities are not always fully used. On the other hand, popularity
of mobile edge computing which aims to replace the traditional centralized
powerful cloud with multiple edge servers is rapidly growing. In particular,
applications having strict latency requirements can be best served by the
mobile edge clouds due to a reduced round-trip delay. In this paper we propose
a Multi-Path TCP (MPTCP) enabled mobile device cloud (MDC) as a replacement to
the existing TCP based or D2D device cloud techniques, as it effectively makes
use of the available bandwidth by providing much higher throughput as well as
ensures robust wireless connectivity. We investigate the congestion in
mobile-device cloud formation resulting mainly due to the message passing for
service providing nodes at the time of discovery, service continuity and
formation of cloud composition. We propose a user space agent called congestion
handler that enable offloading of packets from one sub-flow to the other under
link quality constraints. Further, we discuss the benefits of this design and
perform preliminary analysis of the system.
