We present a distributed particle filtering algorithm for target tracking in sensor networks. Several existing algorithms rely on the establishment and maintenance of a spanning path or tree. This is challenging in networks with dynamic topologies induced by mobile nodes and changing wireless conditions; the algorithms are vulnerable to link or node failure. More recent algorithms employ consensus...
In many applications of sensor-equipped mobile vehicle networks, an energy-efficient communication solution is required due to the limited battery on the vehicle. There are certain characteristics of vehicle-based networks that set them apart from typical sensor networks, namely that they are mobile and consist of only a few nodes. We adopt a design philosophy that optimizes the networking approach...
As the non-stop development of wireless sensor network, its application was enormous. Control network based on forest anti-fire was one of the application fields. This paper made simulation on several scenarios in order to produce the best effect on data collecting and transmission, including different setting pattern of sensor nodes, the amount of nodes and their movement pattern. All of them were...
ldquoCasattentardquo (Aware home, in Italian) is the demonstrator of a research project on ldquoambient intelligencerdquo, ldquosensor fusionrdquo and ldquowireless sensor networksrdquo. The result is a system composed of fixed and wearable sensor nodes, providing elderly people living alone in their house (but also persons in other situations and environments) with adequate and non intrusive monitoring...
The management of ad-hoc networks raises interesting problems, that are particularly challenging for networks of mobile nodes. Considering the inherent complexity of these systems, the development of distributed applications relying on wireless communication protocols would be greatly simplified by the use of specific tools for supporting testing and step-by-step debugging. In this paper we describe...
