It is our great pleasure to welcome you to the 15th ACM International Symposium on Performance Evaluation of Wireless Ad Hoc, Sensor, and Ubiquitous Networks (PE-WASUN'18) that takes place in Montreal, Canada, on October 28th - November 2nd, 2018. This year's ACM PE-WASUN symposium 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 symposium is to share novel approaches for monitoring, measuring, modeling, simulating, analyzing, optimizing and casestudying the characteristics of ad hoc, sensor, pervasive and ubiquitous networks, as well as exploring and developing new ad hoc networking protocols and tools. ACM PE-WASUN gives researchers and practitioners a unique opportunity to share their perspectives with others interested in the various aspects of performance evaluation The call for papers attracted large number of submissions from Europe, Asia, Africa, North and South America. The technical program committee accepted 16 regular papers, which cover a variety of topics, including experimental analysis, simulation, design and performance evaluation of routing, vehicular and sensor networks. We hope that |
