In 2003, it was held in Montreal, and in 2004 it was held in Vancouver. 2005 was the ?rst yearfortheconferencetomoveoutsideofCanada.Thepurposeoftheconference is to create a collaborative forum between mathematicians, computer scientists, and engineers for research in the ?eld of mobile ad hoc and sensor networks. In 2005, we received over 100 submissions from 22 di?erent countries: Australia,Canada,China,France,Germany,Greece,India,Ireland,Italy,Japan, Korea, Malaysia, Mexico, Nepal, Nigeria, Pakistan, Poland, Spain, Sweden, Tunisia, the UK, and the USA - a true international conference.

We are grateful to our Technical Program, Organizing, and Steering C- mittees; without their help, expertise, and experiencewe could not haveselected such a ?ne program. We thank Jorge Urrutia of the Instituto de Matem' aticas, Universidad NacionalAut' onoma de M' exico,and J.J. Garcia-Luna-Acevesof the Computer Engineering Department, University of California, Santa Cruz for - cepting our invitation to speak at the conference. Special thanks are due to the crewfromtheFacultaddeCienciasF' ?sico-Matem' aticasUniversidadMichoacana for handling the local arrangements, and to the Mobile Adhoc Research Lab at Arizona State University for handling odd jobs on a moment's notice.
