Because of the increasing interest in mobile ad hoc networks (MANETs) and their inherent similarities to peer-to-peer networks a large number of routing protocols based on peer-to-peer networks have recently been presented to provide distributed network applications with e cient and indirect routing for MANETs. Thomas Zahn and Jochen Schiller suggested(More)
The precedence effect describes the phenomenon whereby echoes are spatially fused to the location of an initial sound by selectively suppressing the directional information of lagging sounds (echo suppression). Echo suppression is a prerequisite for faithful sound localization in natural environments but can break down depending on the behavioral context.(More)
Name services for mobile ad hoc networks are essential to discover and bind resources given by their name or URI to a specific network address. As there is no fixed infrastructure available in MANETs, nodes cannot rely on any DNS-like system as is taken for granted in the Internet. To keep up with the dynamicity of MANETs, a name service needs to be(More)
DHT can locate objects in a peer-to-peer network within an efficient amount of overlay hops. Since an overlay hop is likely to consist of multiple physical hops, the ratio between the number of physical hops induced by the overlay routing process and the number of physical hops on a direct physical path is often significantly lopsided. Recently, some(More)
As mobile ad hoc networks (MANETs) become ever more popular, it also becomes more and more interesting to build distributed network applications (e.g. data storage, etc.) that have been successfully built using DHTs on the Internet in such MANETs. For this purpose, DHT substrates especially designed for the use in MANETs have been recently proposed. In this(More)
We investigate the feasibility of content distribution between devices mounted in moving vehicles using commodity WiFi. We assume that each device stores content in a set of files, and that each file has a version number. When two devices come into wireless range, they attempt to synchronize the latest versions of any files they have in common. This is(More)
would like to take this opportunity to thank all the people that supported me during this time personally and professionally. First of all, I would like thank Prof. Jochen Schiller who has been my primary adviser over the past three years. Without his support and inspiration as well as the confidence and freedom that he has given me to pursue my ideas, this(More)
Recently, approaches to DHT-style key-based routing explicitly designed for the use in mobile ad hoc networks (MANETs) have been proposed. However, as DHTs are usually no applications as such, a very practical distributed application running on top of such mobile DHTs could be resource discovery. Therefore, in this paper, a DHT-based approach to resource(More)
We describe a biological inspired model of binaural sound localization using interaural time di erences (ITDs). To handle the problem of temporal coding and to facilitate a hardware implementation in analog VLSI, the simulation of the system is based on a spike response model. This neuron model takes up physiological properties like postsynaptic potentials(More)
