An Address-Event Image Sensor Network
We discuss an imaging architecture for sensor pixel in the ALOHA signals an event when a certain amount network applications, that employs a 32 x 32 Address-Event of photons are received, and due to physical restrictions of Representation (AER) imager. At the sensor level, pixels convert integrated circuits their output is multiplexed into a 10-bit bus. light intensity into a pulse density modulated stream of address nTeg theireoutputi uplexento a it bus. events. Two different types of COTS wireless radio nodes are t iscsitestnh eA r -Eet Representation, gineachused, along with two separate approaches to wireless data event is represented by the 10-bit address of the originating transmission - one as a train of AER addresses, and the other as pixel (5 bits for the x coordinate and 5 for the y). a histogram of the active pixels. Information transmitted in the The ALOHA utilizes a standard Acknowledge-Request prolimited-bandwidth network yields effective means for detection tocol to comm...
