In this thesis, performances of some Mobile IP handoff schemes have been compared. The comparison has been based on simulation results. Simulation study has been carried out with a MIP model developed using OMNeT++ and available model frameworks. The literature on Mobile IP and several improvements including handoff management schemes have been surveyed. A MIP model has been constructed and then validated with the help of some scenarios in the literature, especially the one found in [7]. The model has been then used to investigate performances of FMIP. The study also included performance of FMIP under local traffic where mobile hosts communicate with each other in the same domain. Simulations are carried out under several scenarios involving UDP and TCP transfers. Mobile host speed and base station buffer size variables have been changed throughout the simulations. The result show that use of L2 triggers reduces handoff latency as both FMIP Post-Reg and Pre-Reg have better performance than HMIP without L2 triggers. The results also show that FMIP Post-Reg is a good candidate for future MIP infrastructures with its low latency handoff characteristics due to bidirectional tunneling between old and new points of attachment. Moreover, the results suggest that FMIP Post-Reg is also the best handoff scheme under local traffic where mobile hosts communicate among each other in the same foreign network.

Investigation of gmpls applications in optical systems Göken, Burcu; Ergül, Rüyal; Department of Electrical and Electronics Engineering (2005) In this study, possible applications of label switching in large area, fully optical networks are investigated. The objective was to design a label assignment method by using Generalized Multi-Protocol Label Switching (GMPLS) concept to get an efficient optical network operation. In order to fulfill this objective, two new approaches were proposed: a label assignment method and a concatenated label structure. Label assignment method was designed to provide an efficient utilization of resources. Concatenated...
Resource management in callular communication networks with subscriber profile prediction Yılmaz, Nusrat; Ergül, Rüyal; Department of Electrical and Electronics Engineering (2005) In this study, a dynamic resource management and subscriber profile prediction scheme for mobile communication systems is presented. The aim is to achieve a high level of QoS for both handoff calls and new calls, while at the same time to improve the utilization of wireless network resources. The simultaneous satisfaction of these two actually conflicting interests will be thanks to two major key features. First, it will be due to the individual subscriber profile based prior information about handoff reser...
MMSE based iterative turbo equalization for antenna switching sytems Yıldırım, Recep Ali; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2010) In this thesis, we study the performance of an antenna switching (AS) system in comparison to an Alamouti coded system. We analyze the outage probabilities and propose minimum mean-squared error based iterative equalizers for both systems. We see from the outage probability analysis of both systems that the AS system may achieve the same diversity order of the Alamouti coded scheme contingent on the transmission rate and constellation size. In the proposed receiver, MMSE equalization and channel decoding ar...
On qos multicast routing protocols Bereketli, Alper; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2005) Multicasting is a technique used for distributing data packets from one or more sources to a set of receivers on interconnected networks. Currently developing network applications bring specific quality of service (QoS) requirements like bounded delay, minimum bandwidth, and maximum data loss rate. Providing the required quality of service addresses routing and resource reservation concepts. In this study, a literature survey is carried out on traditional and QoS multicast routing protocols, and the need fo...
Implementation of stanag 428 hf modem software on tms320c54x digital signal processor Örümlü, Erhan; Baykal, Buyurman; Department of Electrical and Electronics Engineering (2004) In this research, STANAG 4285 HF modem software is implemented on TMS320C54x fixed point digital signal processor. The software is optimized in order to meet real-time operation requirements. A fractionally spaced least mean square (LMS) decision feedback equalizer (DFE) is employed for the receiver. In order to improve the convergence of the LMS algorithm a multipass technique is utilized. Based on Watterson̕s model, an HF channel simulator is employed for evaluating the performance of the modem. The simul...
