Communications: Wireless in Developing Countries and Networks of the Future The present book contains the proceedings of two conferences held at the World Computer Congress 2010 in Brisbane, Australia (September 20-23) organized by the International Federation for Information Processing (IFIP): the Third IFIP TC 6 Int- national Conference on Wireless Communications and Information Technology for Developing Countries (WCITD 2010) and the IFIP TC 6 International Network of the Future Conference (NF 2010). The main objective of these two IFIP conferences on communications is to provide a platform for the exchange of recent and original c- tributions in wireless networks in developing countries and networks of the future. There are many exiting trends and developments in the communications industry, several of which are related to advances in wireless networks, and next-generation Internet. It is commonly believed in the communications industry that a new gene- tion should appear in the next ten years. Yet there are a number of issues that are being worked on in various industry research and development labs and universities towards enabling wireless high-speed networks, virtualization techniques, smart n- works, high-level security schemes, etc. We would like to thank the members of the Program Committees and the external reviewers and we hope these proceedings will be very useful to all researchers int- ested in the fields of wireless networks and future network technologies.
