An approach for energy efficient service oriented architecture for sensor networks

Abstract

Wireless sensor networks offer an increasingly attractive method for data gathering in distributed system architectures and dynamic access via wireless connectivity. However, wireless sensor networks have limitations with respect to resources and energy consumption, which lead to increased complexity for application developers and often results in applications that are closely coupled with network protocols. One solution for de-coupling applications from the underlying protocols is to use a service-oriented Middleware. However, the limitations make the use of such an approach a challenge due to the overhead of the SOAP protocol. This overhead becomes more significant if the size of the transmitted data is small in comparison to the tagging text, causing nodes with limited power to waste valuable energy. In this paper we discuss the overhead issues associated with using SOAP in wireless sensor networks. We then present two methods for minimizing the effect of the overhead to help in the design of efficient service oriented architectures. Our study shows significant savings in transmission time and message size may be achieved which may be as high as 60% of transmission time or 75% of size in special situations.

A Service Oriented Routing Scheme for Internet of Things

“…Cross-layer analysis is an important feature and an improved problem in SOA [2]. In cross-layer networks, a software layer based on middleware technology is added as the interface of two layers to solve the interconnectivity of the cross-layer problem [8].…”

A Study of Open Middleware for Wireless Sensor Networks

“…Due to the nature of the deployment, nodes are intended to be disposable, so unlike traditional wireless devices such as smart phones the power supply unit cannot always be recharged over its operational lifetime. Thus energy efficiency and preservation is a major research issue for both the design of the physical device itself and the software that runs on it [4]. The wireless sensor networks middleware can be seen as a kind of lower layer pervasive computing middleware.…”

“…Middleware based on SOA (Service Oriented Architecture) is a software layer that rests between the operating system and the application software which can help in hiding the operating system variations, underlying hardware constraints and the complexity of sensor network interconnectivity. Middleware provides a potential solution for bridging the gap between the high-level requirements of applications and the hardware constraints of the wireless sensor networks [4].…”
