Multicast qos support in ieee 802.16

摘要

It is our great pleasure to welcome you to the 3^rd ACM International Workshop on QoS and Security for Wireless Mobile Networks -- Q2SWinet 2007. Continuing the tradition of the two previous Q2SWinet events held in Montreal (Canada) and Torremolinos (Spain), this year's workshop reaffirms the relevance and interest of research on QoS and Security topics in wireless systems. This workshop has become a wonderful forum for discussion and presentation of original ideas, recent results and achievements on various issues and challenges related to QoS and Security on different layers and different technical viewpoints. The objective of the workshop is to give researchers and practitioners a unique opportunity to share and enlarge their perspectives and ideas with each other through a stimulating program. >The call for papers of this workshop has attracted 54 quality submissions from Asia, Canada, Europe, Africa, and the United States. The program committee accepted 18 papers, which represent a 33% acceptance rate and cover a variety of topics, including QoS management in wireless/mobile systems, scheduling, routing, multicast, mobility, and security management. In addition, the program includes a poster session that hosts ten relevant paper contributions on the same topics. The accepted papers come from 16 countries, reflecting the fact that this workshop is very international. We hope that the proceedings will serve as a valuable reference for the worldwide researchers and developers working on wireless systems, mobile applications and services. >Based upon the TPC recommendation, the following three papers have been selected as candidates for the Q2SWinet 2007 Best Paper Award: >"A Multi-channel Defense Against Jamming Attacks in Wireless Sensor Networks", Ghada Alnifie and Robert Simon (George Mason University, USA) "A Dynamic Bandwidth Allocation Algorithm for Supporting Real-time Applications in 802.15.3 WPANs", G. Boggia, P. Camarda, L. A. Grieco, G. Tomasicchio (DEE - Politecnico di Bari, Italy) "Decentralized Group Key Management for Dynamic Networks Using Proxy Cryptography", Junbeom Hur, Youngjoo Shin, Hyunsoo Yoon (KAIST, Korea).
