In society today, mobile communication and
mobile computing have a significant role in every aspect of our
lives, both personal and public communication. However, the
growth in mobile computing usage can be enhanced by
integrating mobile computing into cloud computing. This will
result in emerging a new model called Mobile Cloud Computing
(MCC) that has recently attracted much attention in academic
sector. In this work, the main challenges and issues related to
MCC are outlined. We also present the recent work and
countermeasure solutions that are proposed by researchers to
counter the challenges and lastly, crucial open research and
issues that direct future research are highlighted.
