Maximizing network-lifetime in large scale heterogeneous wireless sensor-actuator networks

摘要

It is our great pleasure to welcome you to the 4^th ACM International Workshop on Performance Evaluation of Wireless Ad Hoc, Sensor, and Ubiquitous Networks (PE-WASUN'07) that takes place in Chania, Crete Island, Greece on October 22-26, 2007. This year's ACM PE-WASUN workshop brings together scientists, engineers, and practitioners to share and exchange their experiences, discuss challenges, and report state-of-the-art and in-progress research on all aspects of wireless ad hoc, sensor, and ubiquitous networks with a specific emphasis on their performance evaluation and analysis. The mission of the workshop is to share novel approaches for monitoring, measuring, modeling, simulating, analyzing, optimizing and case-studying the characteristics of ad hoc, sensor, pervasive and ubiquitous networks, as well as exploring and developing new ad hoc networking protocols and tools with performance advantages. ACM PE-WASUN gives researchers and practitioners a unique opportunity toshare their perspectives with others interested in the various aspects of performance evaluation. >The call for papers attracted 31 submissions from Europe, Asia, the North America and the South America and the Middle East. The technical program committee accepted 10 long papers (which represents a 32% acceptance rate), 4 short papers and 3 poster papers that cover a variety of topics, including energy-efficient protocols design for sensor networks, simulation of sensor networks, performance evaluation of routing protocols, end-to-end transport performance, services discovery modeling, quality of service, performance evaluation of RFID networks. We hope that these proceedings will serve as valuable references for researchers and developers in the field of wireless ad hoc, sensor and ubiquitous networks.
