Green computing has emerged as a hot topic leading to a need to understand energy consumption of computations. This need also extends to devices with limited resources as are common in the internet of things. RESTful services have shown their potential on such devices, but there are many choices of frameworks for their development and execution. Current research has analysed performance of the frameworks...
Performing functionality testing in serviceoriented architectures is not a trivial task. The difficulty is especially the large number of components that may be present in a SOA such as brokers, providers, service registries, clients, monitoring tools, data storage tools, etc. Thus, in order to facilitate the process of conducting functional testing and capacity planning in service-oriented systems,...
This paper analyzes the execution behavior of web services on devices with limited resources. The experiments compare web services in the Axis2 and CXF frameworks analyzing performance and power consumption. To determine which framework is better suited for service provision, a testing environment and a performance and energy evaluation between them are presented. We show that the Raspberry Pi can...
There is an increasing trend of accessing multimedia and web services embedded with Presence service over the mobile, which have driven the telecom operators to look for the new and better ways to provide such services. Presence service puts a lot of load on the IMS network and it can contribute 50% or more to the total signaling load which can increase end-to-end delay. In this paper we have analyzed...
With prevalence and convenience of network services, the Quality of Service (QoS) has become one of the biggest concerns for Internet Service Provider (ISP). Some International standards organizations such as IETF and ITU-T have defined standards related to network performance metrics and numerous researches have focused on this field. However, most existing research works on service performance are...
Mobile and nomadic devices such as cell phones and PDAs have evolved in recent years from resource constrained appliances to highly connected and increasingly powerful devices. This in turn has led to the development of standardized platforms most notably Windows mobile, Java micro edition, Android and the IPhone OS which enable third party developers to build applications fairly easy. Thanks to the...
