Welcome to WoWMoM 2002, the Fifth ACM International Workshop on Wireless Mobile Multimedia, as we move to the era of wireless data services that opens up a lot of challenging research issues and business opportunities.When Marco Conti (CNR, Pisa, Italy) and Dipankar Raychaudhuri (WINLAB/Rutgers Univ.) accepted to serve as TPC Co-Chairs, I was confident about the technical quality of the workshop program. With the help of an excellent array of international TPC members, they have done an outstanding job of attracting highest quality submissions worldwide and selecting the very best ones for presentation at the workshop. This is significant given that the WoWMoM 2002 submission deadline was not extended and passed well before MobiCom decisions were made. You would agree with me that the workshop proceedings that you're holding speaks for itself. In addition, Dipankar has organized a technical panel on a timely and controversial topic. Please join me in acknowledging the dedication and hard work of the TPC Chairs and their team. They truly deserve our heartfelt thanks.
Providing stochastic delay guarantees through channel characteristics based resource reservation in wireless network
This paper is directed towards providing quality of service guarantees for transmission of multimedia traffic over wireless links. The quality of service guarantees require transmission of packets within prespecified deadlines. Oftentimes, bursty, ...
Proxy-based TCP-friendly streaming over mobile networks
Mobile media streaming is envisioned to become an important service over packet-switched 2.5G and 3G wireless networks. At the same time, TCP-friendly rate-adaptation behavior for streaming will become an important IETF requirement. In this paper we ...
A scheduling algorithm for transporting variable rate coded voice in bluetooth networks
In the current Bluetooth specification voice traffic is transmitted using synchronous connection-oriented (SCO) links. Only uncompressed voice connections with Pulse Code Modulation (PCM) are supported, and 64Kbps bandwidth is assigned to each voice ...
A label-switching packet forwarding architecture for multi-hop wireless LANs
A router in wired network typically requires multiple network interfaces to act as a router or a forwarding node. In an ad-hoc multi-hop wireless network on the other hand, any node with a wireless network interface card can operate as a router or a ...
TCP behavior across multihop wireless networks and the wired internet
Emerging wireless ad hoc networks find their most important applications in untethered, mobile, multihop scenarios where there is no wired infrastructure. Yet, when the wired infrastructure (say, the Internet) is within reach, opportunistic connections ...
Coping with communication gray zones in IEEE 802.11b based ad hoc networks
Our experiments with IEEE 802.11b based wireless ad hoc networks show that neighbor sensing with broadcast messages introduces "communication gray zones": in such zones data messages cannot be exchanged although the HELLO messages indicate neighbor ...
A cooperative cache architecture in support of caching multimedia objects in MANETs
This paper presents a cooperative caching architecture suitable for continuous media (CM) proxy caching in MANET environments. The proposed scheme introduces an application manager component, which is interposed between traditional Internet CM ...
EMWIN:: emulating a mobile wireless network using a wired network
Test and performance evaluation of protocols and algorithms in mobile wireless networks is known to be challenging. Due to the highly varying characteristics of mobile wireless networks, one cannot merely rely on either network simulation or a testbed. ...
Power-aware video decoding using real-time event handlers
Multimedia applications have to receive sufficient resource allocations to maintain their desired levels of Quality of Service (QoS). On the other hand, in mobile environments, the devices on which these applications must run have to minimize power ...
Power-aware data management for small devices
Pervasive computing devices such as Personal Digital Assistants (PDAs) and laptop computers are becoming increasingly ubiquitous. The future promises even more advanced devices such as digital watches, jewelry, and even clothing. However, as pervasive ...
Supporting diverse mobile applications with client profiles
We describe a best-effort scheme to support diverse applications in low-bandwidth mobile networks. The improvements due to our scheme are motivated by the observation that different applications typically have different preferences for latency and ...
Multicast in 3G networks:: employment of existing IP multicast protocols in UMTS
In this article we discuss the use of commonly deployed IP multicast protocols in UMTS networks. We analyze three possible UMTS multicast architectures, all employing standard IP multicast protocols. We study the architectures' ability to handle: group ...
Multicasting vs. unicasting in mobile communication systems
We evaluate the multicasting gain over unicast in the cellular networks, where cells are engineered for a specific target call blocking probability. Our approach is Monte-Carlo simulation of dynamic multicast connections, and the traditional Engset ...
Satellite grouping and routing protocol for LEO/MEO satellite IP networks
The rapid growth of Internet-based applications pushes broadband satellite networks to carry on IP traffic. In previously proposed connectionless routing schemes in satellite networks, the metrics used to calculate the paths do not reflect the total ...
