Welcome to the Second ACM International Workshop on Wireless Mobile Applications and Services on WLAN Hotspots (WMASH'2004). We take great pleasure in presenting you with a workshop on a very hot, timely, and challenging topic.
In a very rapid evolution of wireless networks, characterized by sudden rise and fall of technologies and solutions, the success of public WLAN Hot-Spots is continuing unabated. We recall that, last year, the first edition of this workshop was motivated by the attempt to tackle, in a timely manner, the emergence of the public WLAN phenomenon. This year, we are continuing to witness a great and massive interest from both the research community as well as from operators and hotspots deployers on public WLANs. We thus felt the need to maintain WMASH alive, and make it become a forum for the research community to convene and discuss technical and business challenges behind the evolution of WLAN from cable replacement to public access mean.
This year, WMASH has had a success well beyond our best expectations. The number of submissions has grown of about 50% with respect to last year's edition. We received a total of 47 submissions from 23 countries. The workshop program includes 15 excellent papers by authors from 7 countries, and many high quality submissions could not be accommodated for the space limitation. In addition to the presentation of accepted papers, the program also contains an exciting panel discussion on technical and business issues behind the evolution of WLAN hot-spots and hot-zones.
Behind a successful workshop, there is the tireless effort of many people which have smoothly and silently contributed to its organization. We would like to sincerely thank Dr. Parviz Kermani and Dr. Sung-Ju Lee, former organizers of WMASH 2003, for their expert suggestions and support "behind the scene." A depth of gratitude is owed to Dr. Anand Balachandran, our publicity chair, to Prof. Javier Gomez-Castellanos, our publication chair, and to Dr. Milind Buddhikot, our Panel Chair. They helped us with their invaluable talent and time to make this Workshop a reality. Many thanks is owed to the Technical Program Committee members and reviewers who thoroughly helped us select quality papers amongst many submitted manuscript. We had a well-balanced TPC with 28 members in total, with 16 from North America, 1 from Central America, 8 from Europe, and 3 from Asia. 14 members are in academia while 14 members are from the industry.

The advent of the mobile wireless Internet has created the need for seamless and secure communication over heterogeneous access networks such as IEEE 802.11, WCDMA, cdma2000, and GPRS. An enterprise user desires to be reachable while outside one's ...
Network selection and discovery of service information in public WLAN hotspots
In a public WLAN hotspot, a roaming mobile terminal (MT) may be within radio range of more than one access point (AP), each of which may or may not have roaming agreements with the service provider of the user of the MT. In this case, the MT may need to ...
A scalable framework for wireless network monitoring
The advent of small form-factor devices, falling hardware prices, and the promise of untethered communication is driving the prolific deployment of wireless networks. The monitoring of such networks is crucial for their robust operation. To this end, ...
LOCATOR: location estimation system For wireless LANs
With the wide spread growth of mobile computing devices and local area wireless networks, wireless network providers have started to target the users with value-added services based on the users' location information. Thus, location awareness and user ...
Extracting places from traces of locations
Location-aware systems are proliferating on a variety of platforms from laptops to cell phones. Locations are expressed in two principal ways: coordinates and landmarks. However, users are often more interested in "places" rather than locations. A place ...
Proximity services supporting network virtual memory in mobile devices
Wireless networked embedded terminals like personal digital assistants, cell-phones or sensor nodes are typically memory constrained devices. This limitation prevents the development of applications that require a large amount of run-time memory space. ...
