his paper presents the design, implementation, and evaluation of
Cricket, a location-support system for in-building, mobile,
location-dependent applications. It allows applications running on
mobile and static nodes to learn their physical location by using
listeners that hear and analyze information from beacons
spread throughout the building. Cricket is the result of several
design goals, including user privacy, decentralized administration,
network heterogeneity, and low cost. Rather than explicitly tracking
user location, Cricket helps devices learn where they are and lets
them decide whom to advertise this information to; it does not rely on
any centralized management or control and there is no explicit
coordination between beacons; it provides information to devices
regardless of their type of network connectivity; and each Cricket
device is made from off-the-shelf components and costs less than
U.S. $10. We describe the randomized algorithm used by beacons to
transmit information, the use of concurrent radio and ultrasonic
signals to infer distance, the listener inference algorithms to
overcome multipath and interference, and practical beacon
configuration and positioning techniques that improve accuracy. Our
experience with Cricket shows that several location-dependent
applications such as in-building active maps and device control can be
developed with little effort or manual configuration.
