This paper describes the mobile Ad-Hoc (wireless) network (MANET) for emergency scenarios in nuclear power plant (NPP). Authors proposed the system with such properties as flexibility and a self-forming and self-healing network topology that dynamically adjusts to the moving configuration per each intermediate routing node. It is also proposed to integrate MANET and Bluetooth-like technologies to create an unmanned formation of autonomous quadcopters that provides both indoor and outdoor communications coverage inside and outside of the NPP.

The WSN standard IEEE802.15.4 basically uses the unlicensed frequency of 2,4 GHz for data transmission in a variety of devices, standards and applications: IEEE802.11, Bluetooth and etc. In this paper we proposed modified correction codes – based on Residue Number System – to improve the data transmission robustness in WSN. These codes are characterized by high correction characteristics as well as the simplified coding procedure. There are given examples, and circuits of the both coder and decoder are designed for such modified correction codes using the Residue Number System and CPLD.DOI: http://dx.doi.org/10.5755/j01.eee.21.1.6657

The WSN standard IEEE802.15.4 basically uses frequency of 2,4 GHz for data transmission. This unlicensed frequency band is used by a variety of devices, standards and applications: IEEE802.11, Bluetooth and etc. In this paper is considered the increase of data transmission reliability increasing in WSN with the use of Residue Number System error correcting code. These codes have high correcting characteristics and simplified coding procedure.

The authors propose the method for data coding in wireless sensor networks (WSN) based on the transformation of the residue number system and multipath routing. It enables to utilize efficiently the bandwidth of communication channels as well as reduce message delivery time. It is explored the ant algorithm to search an optimal route of data transmission in the wireless sensor network. There is introduced a limitation for the communication radius of the wireless unit that shorts a number of the search decision modes and improves the accuracy of the wireless network simulation. The correspondent software is designed, it allowes exploring the dynamics of finding the optimal transmission path in WSN in case of different algorithm settings, and exploring the impact of the elite ants on the accuracy of the found path.

In this paper we proposed the method of correcting codes formation based on Residue Number System. The proposed method provides the formation of RNS correcting codes of the input data which is represented in a positional notation.
