An Efficient and Extensible Service based Sensor Access Architecture

This paper aims to design and implement an efficient service based sensor access architecture for web based interaction of sensor nodes. The future sensor networks are envisioned as comprising heterogeneous devices assisting to a large range of applications. Interoperability is required for such heterogeneous devices. To achieve this, Service Oriented approach for the data acquisition from sensor network, and an extensible architecture in which this web services based deployment is extended to CLOUD. The data acquisition from sensor network is done in which sensor nodes are service providers and applications are clients of such services. The service oriented architecture for sensor network has been implemented in such a way that for every specific requirement of the client, the services of the sensors are invoked through a registry and the specific changes in the sensed parameters are also notified as auditable event using push interaction pattern of SOA. Hosting sensor node’s data as web service challenges battery life, bandwidth, processing power constraints of low power sensor nodes. The designed based Gateway reduces the power consumption of sensor nodes hence maximizes the network lifetime. The main goal is to design a flexible and efficient architecture in which sensor networks data can be accessed by applications.
