Cooperative dynamic eHealth service placement in Mobile Cloud Computing

Abstract

In the area of mobile applications, emerging eHealth applications used in conjunction with wearable medical sensor devices and personal devices are being adopted increasingly by people with the aim to improve their lifestyle and health. eHealth providers, willing to provide remote eHealth management, are integrating Wireless Body Area Networks (WBANs) technology and Cloud Computing. Cloud computing has the benefit to eliminate the need of maintaining costly hardware, software and network infrastructures. This combination of Cloud Computing and Mobile Computing is known as Mobile Cloud Computing (MCC). It allows eHealth providers to deploy instantly and on demand their eHealth services to monitor people's health status. In this paper, we propose a cooperative strategy between a mobile operator and a cloud provider for an efficient eHealth service placement in the cloud which take into account the network latency. We highlight the importance of mutual coordination between them to minimize the cost of deployed services while maintaining customers satisfaction.
