Abstract: The method and device for multimedia data encoding in wireless sensor networks were developed. It provides the increase of the total communication channel bandwidth, data flow adaptive distribution, depending on the channel characteristics, it increases the reliability of the transmission through the usage of corrective properties of the residue number system. Conversion of pixels in the developed device is carried out once per cycle using parallel-serial multi-bit adders and incomplete encoders based on the direct addition method. Selected co-prime modules provide conversion of 24-bit images. The resulting balances are transferred in parallel channels with multipath routing.

 

Keywords: Wireless multimedia sensor networks, Residue number system, Image coding, Multipath routing
