Opis

During my PhD study, I have focused on two research areas of wireless communication: IEEE 802.11 network performance analysis, and wireless cooperative retransmission. The first part of this thesis focuses on IEEE 802.11 network performance analysis. In this area, my work includes the development of three analytical models for various aspects of IEEE 802.11 network performance analysis. Markov chain technology has been used as basic modelling tool in my work, and extesnive simulation study has demonstrated the accuracy of my proposed modles. The second part of this thesis focuses on wireless cooperative retransmission. In this thesis, two uncoordinated distributed wireless cooperative retransmission strategies for single-hop connection are presented. In the proposed strategies, each uncoordinated cooperative neighbour randomly decide whether it should transmit to help the frame delivery depending on some pre-calculated optimal transmission probabilities.
