—One of the most common and important applications of wireless sensor networks is target tracking. We study it in its most basic form, assuming the binary sensing model in which each sensor can return only information regarding target's presence or absence within its sensing range. However, unlike of the most of traditional approaches to binary sensing, we allow sensors to recognize not only target's range but also a sector within the circular range around it. This assumption is justified by increasing importance of sensors with a directionally limited sensing range caused by a directional antenna or limited measurement capabilities. Examples of such sensors include cameras, infrared sensors, ultrasonic sensors, etc. For simplicity, we assume that either a group of sensors are collocated in a single spot providing 360 degree coverage or a sensor has multiple antennas or camera providing such coverage. A novel, real-time and distributed target tracking algorithm with directi...
