This volume contains papers presented at The 2013 International Conference on Wireless Networks (ICWN'13). Their inclusion in this publication does not necessarily constitute endorsements by editors or by the publisher.

Foreword

It gives us great pleasure to introduce this collection of papers to be presented at the 2013 International

Conference on Wireless Networks (ICWN’13), July 22 through 25, 2013, at The New Tropicana Hotel,

Las Vegas, USA.

An important mission of the World Congress in Computer Science, Computer Engineering, and Applied

Computing (a federated congress to which this conference is affiliated with) includes "Providing a unique

platform for a diverse community of constituents composed of scholars, researchers, developers, educators,

and practitioners. The Congress makes concerted effort to reach out to participants affiliated with diverse

entities (such as: universities, institutions, corporations, government agencies, and research centers/labs)

from all over the world. The congress also attempts to connect participants from institutions that have

teaching as their main mission with those who are affiliated with institutions that have research as their

main mission. The congress uses a quota system to achieve its institution and geography diversity

objectives." By any definition of diversity, this congress is among the most diverse scientific meeting in

USA. We are proud to report that this federated congress has authors and participants from 82 different

nations representing variety of personal and scientific experiences that arise from differences in culture and

values. As can be seen (see below), the program committee of this conference as well as the program

committee of all other tracks of the federated congress are as diverse as its authors and participants.

The program committee would like to thank all those who submitted papers for consideration. About 75%

of the submissions were from outside the United States. Each submitted paper was peer-reviewed by two

experts in the field for originality, significance, clarity, impact, and soundness. In cases of contradictory

recommendations, a member of the conference program committee was charged to make the final decision;

often, this involved seeking help from additional referees. In addition, papers whose authors included a

member of the conference program committee were evaluated using the double-blinded review process.

One exception to the above evaluation process was for papers that were submitted directly to

chairs/organizers of pre-approved sessions/workshops; in these cases, the chairs/organizers were

responsible for the evaluation of such submissions. The overall paper acceptance rate for regular papers

was 28%; 10% of the remaining papers were accepted as poster papers (at the time of this writing, we had

not yet received the acceptance rate for a few individual tracks.)

We are very grateful to the many colleagues who offered their services in organizing the conference. In

particular, we would like to thank the members of the Program Committee of ICWN’13, members of the

congress Steering Committee, and members of the committees of federated congress tracks that have topics

within the scope of ICWN. Many individuals listed below, will be requested after the conference to provide

their expertise and services for selecting papers for publication (extended versions) in journal special

issues as well as for publication in a set of research books (to be prepared for publishers including:

Springer, Elsevier, BMC, and others).
