“…Time synchronization and energy efficiency for wireless sensor networks have been studied thoroughly in the literature [19,20,21,22,5,18,23] for different applications. Beside to improving time synchronization accuracy and energy effi-ciency, a challenging task is how to balance the trade-off between such conflicting attributes [9,10].…”

The ubiquity of sensors has offered great opportunities to monitoring infrastructures to track the real-time state of observed environments. Monitoring systems rely on synchronous massive data to calculate the environment state. However, collecting and communicating massive data usually leads to expensive energy consumption due to high sampling frequency and communication cost for the sensors operation. Clamp-on wireless sensors are a flexible plug-and-play technology easy to deploy where sensors operate on integrated batteries. This paper introduces a highly accurate time synchronization protocol to coordinate the operation of individual clamp-on sensors deployed as an energyconstrained monitoring solution. While maintaining sensors highly synchronized, the proposed protocol reduces drastically data communication and energy consumption of the sensor network. To minimize the energy consumption further, we optimize the protocol behavior using a genetic algorithm. The protocol has been modeled in VDM for formal analysis, implemented and compared to a state of the art protocol.

The Ubiquitous sensor network (USN) is composed of several heterogeneous sensors with a variety of characteristics. An application based on the sensor network also has various requirements to provide services to users. Therefore it is important to develop the common USN middleware for flexible integration between the sensor networks and applications. Especially, this paper focuses on intelligent service management which is one of the main functions of USN middleware. Several applications in the sensor network environment support not only monitoring services, but also sensor-based context-awareness and intelligent services. In many applications, however, approaches to support intelligent services depend on the application because the standard method has been undefined yet. Therefore this paper proposes a common method for processing intelligent services in USN middleware independent of an application. The proposed method is implemented and evaluated as a component of USN middleware.
