In this paper, we combine inertial sensing and sensor network technology to create a pedestrian dead reckoning system. The core of the system is a lightweight sensor-andwireless-embedded device called NavMote that is carried by a pedestrian. The NavMote gathers information about pedestrian motion from an integrated magnetic compass and accelerometers. When(More)
by Yashan Sun Distributed coordinated multiple agent system attracts significant interests in the recent decades. Typical applications include unmanned autonomous vehicle formation control, automated highway system and sensor network. A common feature for these applications is that cooperative behaviors are accomplished by interactions among agents wherein(More)
Overload management policies avoid network congestion by actively dropping packets. This paper studies the effect that such data dropouts have on the performance of spatially distributed control systems. We formally relate the spatially-distributed system's performance (as measured by the average output signal power) to the data dropout rate. This(More)
The ability to track the position of the user is an essential part of many applications [7, 4, 2]. It is well known that Global Positioning System (GPS) is limited as a navigation aid by its inability to provide static heading and its lack of availability when used around obstructions (terrain or man-made) or in the presence of jamming. Therefore, it is(More)
Consensus filters [1] provide a distributed way of computing data aggregates in embedded sensor networks. Prior work has suggested that the rate at which such filters achieve consensus is proportional to the number of neighbors. This conclusion, however, is simplistic because it ignores the intrinsic throughput limitation of multi-hop networks. This paper(More)
