The aim of the work is elaboration of the data coding methods and tools for multimedia wireless sensor network, that allows to increase the reliability and functionality. The investigation methods are information and coding theory, residue number system, Galois fields, digital simulation and software emulation. The results of this investigation: The method of network coding data in wireless sensor networks based on the residue number system, which enhances overall network bandwidth by combining packets common nodes and choice modules bit different; a modified system of corrective codes residue number system that have low computational complexity algorithms for encoding / decoding and make it possible adaptive changes in the number of correcting modules; the method of image compression without losses in the remaining classes, which differs from the existing image on the division remains. The method provides increased processing speed and reduce the computational complexity of procedures encoding / decoding by the division of the image into pieces and parallel processing of individual parts; algorithm and software for finding the shortest route in wireless sensor networks with mobile nodes based on the method of ant colonies, which allowed to increase the accuracy of the solutions; developed adaptive encoding and data in WSN, which is different from the existing ability to change the number of test modules and adaptive traffic distribution based on the number of available routes and their status.
