This paper addresses the problem of engineering energy-efficient target detection applications, using unattended Wireless Sensor Networks (WSNs) with random node deployment and partial coverage, for long-lasting surveillance of areas of interest. As battery energy depletion is a crucial issue, an effective approach consists in switching on and off,(More)
In the emerging field of the Internet of Things (IoT), Wireless Sensor Networks (WSNs) have a key role to play in sensing and collecting measures on the surrounding environment. In the deployment of large scale observation systems in remote areas, when there is not a permanent connection with the Internet, WSNs are calling for replication and distributed(More)
The limited node capabilities typical of Wireless Sensor Networks (WSNs) call for crosslayer design optimization. In this paper, we address the problem of designing and operating long-lasting surveillance mobile target detection applications for unattended WSNs with a priori knowledge of the nodes’ positions. In particular, we focus on the cross-layer(More)
The increasing ubiquity and diversity in the resources and functionalities of the devices of the Internet of things claims the need for (1) a device-independent abstraction layer to expose (and consume) device capabilities as services on the network and the need for (2) mechanisms to customize the behaviour of the devices to fulfill new or additional(More)
This paper addresses the problem of engineering energy-efficient target detection applications using unattended Wireless Sensor Networks (WSNs) for long-lasting surveillance of areas of interest. As battery energy depletion is an issue in this context, an approach consists of switching on and off sensing and communication modules of wireless sensors(More)
Wireless sensor network (WSN)-based applications typically require to store data in the network. For instance, in the surveillance of isolated areas, if no sink nodes are present, WSNs may archive observation data that are periodically retrieved by an external agent. In contrast to conventional network data storage, storing data in WSNs is challenging(More)
This paper addresses target detection applications for long-lasting surveillance of areas of interest using unattended Wireless Sensor Networks (WSNs). In this context, to achieve a long system lifetime, sensing and communication modules of wireless sensor nodes may be switched on and off according to a prefixed duty cycle, whose use has an impact on (i)(More)
The specifications of the protocols supporting mobility - MIPv6, NEMO - centralize their key functionalities on the Home Agent, which represents a single point of failure. In the context of the French research project REMORA, we have developed a solution to make Home Agent-based mobility protocols more reliable against the Home Agent failures. This paper(More)
