    Time synchronization in wireless sensor metworks
    (Izmir Institute of Technology, 2008) Kulaklı, Ali Burak; Aytaç, İsmail Sıtkı; Aytaç, İsmail Sıtkı; 03.04. Department of Computer Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    In this thesis, an enhanced synchronization algorithm for Wireless Sensor Networks is proposed. This algorithm uses TPSN (Timing-sync protocol for sensor networks) as a base synchronizer and does modifications on it to achieve a better synchronization with a lower message overhead. Basically, there are three improvements that can be applied onto TPSN, which are clustering the network, chain synchronization among nodes and adaptive synchronization interval. In the first phase of the thesis, a simulation environment is provided for TPSN using pthreads on a Linux computer. This environment helps understanding the parameters that TPSN relies on and testing the algorithm in different simulated environments with different characteristics using the enhancements onto TPSN algorithm. In the second phase, ns2 simulator environment is used to get more precise results and test the modifications. Finally, latest modifications are done on TPSN and all the results are gathered from ns2.

    Implementation of Synchronized Chaotic Systems by Field Programmable Gate Array
    (Izmir Institute of Technology, 2008) Eroğlu, Can; Savacı, Ferit Acar; Savacı, Ferit Acar; 03.05. Department of Electrical and Electronics Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    In this thesis, the geometric properties of chaotic systems are used to determine their synchronization. First, each system is constructed with MATLAB Simulink blocks. Afterwards, feedback control system for synchronization of chaotic systems is proposed by using complete synchronization approach. In the next stage, Simulink designs are translated into System Generator design so that bitstream file which is used to program FPGA is obtained. Finally, the design is implemented into FPGA by dowloading bitstream file into FPGA. As an application of FPGAs the synchronization of chaotic systems have been achieved.
