This book constitutes the refereed proceedings of the Second Asian Internet Engineering Conference, AINTEC 2006, held in Pathumthani, Thailand, in November 2006. The 12 revised full papers presented together with 5 invited papers were carefully reviewed and selected from 36 submissions. The papers are organized in topical sections on service architecture, multicast, performance in WLAN, routing, and multihoming in mobile networks.
The Asian Internet Engineering Conference (AINTEC) brings together researchers and engineers interested in practical and theoretical problems in Internet technologies. The conference aims at addressing issues pertinent to the Asian region with vast diversities of socio-economic and networking conditions while inviting high-quality and recent research results from the global inter- tional research community. The ?rst event was jointly organized by the Internet Education and Research Laboratory of the Asian Institute of Technology (AIT) and the WIDE Project with support from the APAN-TH community. In response to the recent natural disaster in Asia, AINTEC 2005 solicited papers, among other things, on the survival of the Internet in order to provide alternative means of communication in emergency and chaotic situations. The main topics include: Mobile IP Mobile Ad Hoc and Emergency Networks Multimedia or Multi-Services IP-Based Networks Peer-to-Peer Measurement and Performance Analysis Internet over Satellite Communications There were 52 submissions to the Technical Program,and we selected the 18 papers presented in these proceedings. In addition, we have three invited papers and one invited position paper by leading experts in the ?eld. Finally, we would like to acknowledge the conference General Chair, K- chana Kanchanasut of AIT, and the Local Organizers team from AIT, namely, Pensri Arunwatanamongkol, Withmone Tin Latt and Yasuo Tsuchimoto, for organizing and arranging this conference. We are also grateful to the French Ministry of Foreign A?airs through its French Regional Cooperation and the ICT Asia project (STIC-ASIE) for providing travel support.
A comprehensive summary of theoretical and practical developments in LTE Heterogeneous Networks The last decade has witnessed the proliferation of mobile broadband data and the trend is likely to increase in the coming years. Current cellular networks are ill equipped to deal with this surge in demand. To satisfy user demand and maximize profits, a new paradigm to operate networks is needed. Heterogeneous networks, that deploy an overlay of small cells with limited coverage and transmit power, over a macro coverage area is the solution by providing capacity and coverage where it is needed. This book presents a comprehensive overview of small cell based heterogeneous networks within the framework of 3GPP LTE-Advanced which is the major enabler of current and future heterogeneous networks. The book first establishes the basics of LTE standards 8 -10. Wherever relevant, the underlying theory of wireless communications is explained and the signaling and protocol aspects of LTE Releases 8-10 are presented. Next the book presents a systematic study of the inter cell interference (eICIC and FeICIC) mechanisms that have been standardized in LTE releases 10 and 11 to mitigate the interference arising in heterogeneous networks. From simple blank subframe design and implementation, the book discusses more advanced transceiver signal processing and carrier aggregation (CA) based mechanisms to improve performance. Besides data, control channel enhancements such as enhanced PDCCH (ePDCCH) are also discussed. Subsequently the book discusses the possibility of base stations being allowed to coordinate to manage interference. This technique, called CoMP, has the potential of vastly improving network performance. However several practical challenges first have to be overcome before this potential can be realized. The book presents the different CoMP categories introduced in LTE release 11, the required signal processing and the changes that were introduced in Release-11 for supporting CoMP. The book then presents the state of the art developments in heterogeneous networks that are currently taking place in 3GPP with the initiation of Release 12. A whole array of new technologies have been introduced such as dynamic switching of small cells, new carrier types with reduced control signaling, dynamic reconfiguration of TDD-LTE, joint configuration of TDD and FDD via carrier aggregation and lastly advanced MIMO signal processing with three dimensional beamforming. All these technologies will work in unison leading to efficient operations of small cells. The authors thus comprehensively summarize the advances in heterogeneous networks over the last couple of years as reflected in various LTE releases and then look ahead at what to expect in the future. Fully illustrated throughout and with an accompanying website including Matlab code for simulating heterogeneous networks, LTE channel models, and References to 3GPP specifications, contributions, and updates on recent standardization activities. The authors, being involved in LTE standardization, are well placed to give an excellent view on this topic, including valuable background and design rationale.

A timely publication providing coverage of radio resource management, mobility management and standardization in heterogeneous cellular networks The topic of heterogeneous cellular networks has gained momentum in industry and the research community, attracting the attention of standardization bodies such as 3GPP LTE and IEEE 802.16j, whose objectives are looking into increasing the capacity and coverage of the cellular networks. This book focuses on recent progresses, covering the related topics including scenarios of heterogeneous network deployment, interference management in the heterogeneous network deployment, carrier aggregation in a heterogeneous network, cognitive radio, cell selection/reselection and load balancing, mobility and handover management, capacity and coverage optimization for heterogeneous networks, traffic management and congestion control. This book enables readers to better understand the technical details and performance gains that are made possible by this state-of-the-art technology. It contains the information necessary for researchers and engineers wishing to build and deploy highly efficient wireless networks themselves. To enhance this practical understanding, the book is structured to systematically lead the reader through a series of case-studies of real world scenarios. Key features: Presents this new paradigm in cellular network domain: a heterogeneous network containing network nodes with different characteristics such as transmission power and RF coverage area Provides a clear approach by containing tables, illustrations, industry case studies, tutorials and examples to cover the related topics Includes new research results and state-of-the-art technological developments and implementation issues
