Today, the service computing research is focusing on the ubiquitous and on-the-move availability of Internet applications as cloud services. As a result, the mobility is rapidly becoming an important requirement of the future. In addition to that, the integration of mobile and service computing domains enables the existing mobile devices to offer their resources as mobile Web Services (WS). For this reason, these mobile WS are expected to become ubiquitous, as they may be offered by any connected device. Previously, we presented a concept of protecting such mobile WS by using Service Level Agreements (SLA) on mobile devices, where we explained the four primary architectural components of the SLA framework and classified their functions into four fundamental life cycles. In continuation of that, here, we present the detailed performance analysis of the SLA framework, while taking into account the SOAP and REST service access interfaces. Our processing analysis shows the percentage increase due to the SLA overhead compared to the normal unprotected mobile WS. These results are used to evaluate several parameters within the performance metric of the synchronous and asynchronous mobile WS architectures.
