RESTful Web Service Composition
RESTful web services are becoming more popular with the explosive use of smartphone applications. Computing capability of smartphones is generally less powerful than other mobile computing devices. Therefore, it is necessary to offload the computation-intensive part by careful partitioning of application functions across the cloud computing. For this purpose, we make use of RESTful web service. Since, we are not able to make all necessary data within local storages for smartphone applications, because we should access the data from third party servers or vendors. For example, navigation, oil/gas price, public transportation information. So, we propose a novel methodology for accessing the information by RESTful web service composition. The core technology of our methodology is based on automatic conversion between web service and object. The proposed system automatically converts the web service execution result to objects in order for deverlopers to easily compose several web services by using this web service composition service. The result shows that our mobile cloud computing platform performs better as increasing number of cloud nodes.
