Energy efficient and mobility information is a key problem in wireless sensor networks. Save more energy in network processing such as mobility, data aggregation and gateway deployment is a widely used technique. The large-scale deployment of wireless sensor networks and the need for data aggregation, mobility controlling and also necessitate to deploying the gateways among the network, for the purpose...
This paper presents a flexible, efficient and lightweight Wireless Body Area Network (WBAN) Middleware. The Middleware is developed to bridge the communication between mobile device as a gateway and the sensor nodes, and therefore it shields the underlying sensor and OS/protocol stack away from the WBAN application layer. The middleware is coded in the form of lightweight dynamic link library, which...
In a Wireless Sensor Network (WSN), battery power is a limited resource on the sensor nodes. Hence, the amount of power consumption by the nodes determines the node and network lifetime. This in turn has an impact on the connectivity and coverage of the network. One way to reduce power consumed is to use a special Mobile Data Collector (MDC) for data gathering, instead of multi-hop data transmission...
Sensor nodes in ubiquitous sensor network (USN) environments are composed of many sensors and hardware components for various purposes and applications, such as service in the industrial field, the public administration sector, and in life services. A middleware is required for wireless sensors to treat a huge amount of information from sensor nodes. However, the use of a middleware and specialized...
