runtime. Therefore, adaptation module can offer
the appropriate service requests based on the con-
text and resource data. Because the QoS monitoring
module periodically performs checking, if the QoS
levels of a service provided by service providers are
lower than an accepted level of the request, a ser-
vice request module will be notified to launch a
new request for discovery of a new service satis-
fying the new requirements. The advantage of this
model is that the model can automatically recognize
changes in the contexts on a mobile device through
the dependent functionality modules, thereby pro-
viding an effective service request for mobile users
at runtime.
5. OPEN ISSUES AND FUTURE
RESEARCH DIRECTIONS
Several research works contribute to the development of
MCC by tackling issues as presented in the previous sec-
tion. However, there are still some issues which need to be
addressed. This section discusses several open issues and
possible research directions in the development of MCC.
