Mobile Ad Hoc wireless network for pre- and post-emergency situations in nuclear power plant

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.

Wireless sensor networks based on modular arithmetic

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.

A Low-Cost Network Controller for Security Systems

This paper describes the design of a low-cost network controller that can be used to interface sensors to security systems.
