SC948: Motes: Self-Organizing Wireless Networked Micro-Sensors
This course addresses the use of ad hoc network sensors to implement "smart" reconnaissance with various objectives: vehicular/personnel detection and tracking, persistent surveillance, perimeter control, and/or continuous event monitoring (including Military Operation in Urban Terrain, MOUT). The course presents the use of small (<30 in3) micro-sensors (referred to as "motes") within a wireless ad hoc network. The object is to perform tasks previously assigned to larger, more power hungry, sophisticated sensors such as imaging, acoustic, and/or seismic sensors. Through distributed processing of sensor signals within a networked field, motes can accomplish a myriad of tasks formerly relegated to larger sensors. Additionally, mote "fields" can be applied using numerous configurations that allow for novel security and/or military applications. This course introduces the technologies and markets that spawned mote-sized wireless sensors, discusses the design of motes and associated sensors, reveals the mote middleware functionality and implementation requirements, and provides insight concerning mote-field C2 interfaces. Examples are provided, with background information that presents low power ad hoc networking, mote-based sensor design rules, middleware implementations, and issues associated with data exfiltration and mote field deployment. Actual implementations of mote arrays in laboratory and field environments are reviewed along with underlying mote designs for specific applications. Efforts in self-organizing wireless networks stem from several sources: notably DARPA's Network Embedded Sensor Technology program http://www.darpa.mil/ipto/programs/nest/nest.asp (NEST) will be discussed.
