چکیده
We follow the vision of end-systems being connected mainly via wireless technologies to an optical communication infrastructure. We believe that the communication will be based on multimediasupport enhanced Internet, with quality of service support being achieved by segregation rather than reservation. In addition to wireless access also nomadicity and mobility will have to be increasingly supported. In our approach, called AMICA: Adaptable, Mobile; Internet-based Communication Architecture we investigate several crucial aspects of such future systems, following original research hypothesis.

Lizhi Charlie Zhong, Jan M. Rabaey and Adam Wolisz* Berkeley Wireless Research Center, University of California, Berkeley *Telecommunication Networks Group (TKN),Technische Universitaet Berlin, Germany Abstract –We present here a unique modeling approach that reveals the dependency of the overall power consumption on the design parameters in sensor networks. In this two-step approach, we first ...
متن کاملTechnical University Berlin Telecommunication Networks Group Measurements and Stochastic Modeling of a Wireless Link in an Industrial Environment
The design and simulation of coding schemes, medium access control and link layer protocols for future industrial wireless local area networks can be supported by some understanding of the statistic properties of the bit error patterns delivered by a wireless link (which is an ensemble of transmitter, channel, receiver, modems). We present results of bit error measurements taken with an IEEE 80...

IEEE approved the 802.11 standard amendment for QoS support in 2005 after having issued 13 draft versions. Over this period, several technical changes, e.g., regarding the backoff procedure evolved. The original TKN EDCF model, published in 2003 for ns-2.26 is based on 802.11e Draft 2 respective 4 and had to be adjusted accord to the final standard amendment. The resulting novel TKN EDCA model ...
متن کاملPassive Discovery Schemes for Opportunistic Message Relaying Schemes Based on Ieee 802.15.4 Tkn Technical Reports Series
Body sensor networks are an important building blocks for many applications in the areas of healthcare, assisted-living and well-being. Body sensor networks move as a whole, typically together with a person carrying them. One interesting approach to exploit body sensor networks for the dissemination of data are opportunistic message relaying approaches, in which body sensor networks are used as...
متن کاملSystematic Measurement of TCP Performance over Wireless LANs
One challenge in the development of telecommunication networks is the seamless integration of wireless devices into the global Internet. Although it is well known that a wireless end-system suffers from the characteristics of the wireless link systematic measurements are still missing. In this paper we present results of a systematic measurement of TCP performance over wireless LANs. In this me...
