Technology of Sensor Networks
Koval, Miroslav ; Očenášek, Pavel (referee) ; Trchalík, Roman (advisor)
This diploma thesis deals with sensor networking technology, namely about ZigBee. This work consists of two parts - teoretical and practical. The teoretical part is created by some chapters which describe protocols and standards which compose a bases to ZigBee technology. Some parts of this chapter compare ZigBee network with the other wireless solutions and deals with their features. Practical parts is based on properties of available ZigBee devices and summarize communication among sensor network nodes, own ZigBee application, application gateway design and its implementation for ZigBee network monitoring and control from Internet. The last chapter is devoted to discusion about problems and their solutions alternatively about suggestions of next study and improvement this project.

Network Architecture and Interconnection of Embedded Systems
Trchalík, Roman ; Drábek, Vladimír (referee) ; Srovnal, Vilém (referee) ; Švéda, Miroslav (advisor)
The thesis focuses on the architecture of embedded systems. It summarizes the current state of accepted standards from IEEE 1451 family, which deals with creating an environment for the sensors and their involvement in various networks. These standards describe the open, network-independent communication architecture for a sensor-based system. One of the main outcomes of this work is the architectures presented as case studies, which can be used as design patters for embedded applications. They are demonstrated on ZigBee technology suitable mainly for small devices with very low power consumption. Based on these studies the new design of universal gateway was proposed. Its major advantage is that it allows interconnection of the endpoints based on different sensor network technologies. Additionally, the thesis deals with modifying the routing protocol of ZigBee network in order to reduce power consumption required to transmit one data packet.
