50 Advances in Mobile Cloud Computing Systems
In this chapter, we focus on the fundamental approach for design-
ing the off-loading policy of reducing the energy consumption in
mobile cloud computing.
2.3 Policy in Application Off-Loading
In this section, we present off-loading policy for application execution
in mobile cloud computing. Since a mobile application can consist
of a set of tasks, to model the application execution, we construct a
directed acyclic graph as follows:
• In the graph, a node represents a fine-grained task and a link rep-
resents the data dependency between adjacent tasks.
• A specific cost is associated with the node and the link for the com-
putation and communication, respectively. The cost can be energy
consumption or time dela ...
