Mobile peer-to-peer systems have recently got in the lime-light of the research community that is striving to build efficient and effective mobile content addressable networks. Along this line of research, we propose a network coding based file swarming ...

Using p2p systems on multi-hop ad hoc networks is an amazingly interesting challenge. While the features of p2p systems designed for Internet are particularly suitable for ad hoc networking environments, the very assumptions behind their design are ...

Wireless radios of the future will likely be frequency-agile, that is, supporting opportunistic and adaptive use of the RF spectrum. Such radios must coordinate with each other to build an accurate and consistent map of spectral utilization in their ...

Today's mobile devices are growing in number and computational resources. Devices capable of storing gigabytes of digital content are becoming ubiquitous, making them an ideal platform for peer-to-peer content delivery and sharing. However, the always ...

Energy consumption is the most important factor that determines sensor node lifetime. The optimization of wireless sensor network lifetime targets not only the reduction of energy consumption of a single sensor node but also the extension of the entire ...

Distributed applications running on Mobile Adhoc NET- works (MANETs) can benefit from underlying middleware that provides services for self-management. Such services can address the dynamic conditions associated with a MANET's operational environment ...

To achieve the vision of networks that work without any supporting infrastructure, we need wireless ad hoc technology to replace the cabling infrastructure, but we also need self-configuring network and application services to replace the server ...

Mobile ad-hoc networks (MANETs) and distributed hash-tables (DHTs) share key characteristics in terms of self organization, decentralization, redundancy requirements, and limited infrastructure. However, node mobility and the continually changing ...

Mobile peer-to-peer applications recently have received growing interest. However, it is often assumed that structured peer-to-peer overlays cannot efficiently operate in mobile ad hoc networks (MANETs). The prevailing opinion is that this is due to the ...

Nowadays, it is not rare that a mobile node equips multiple interfaces such as Ethernet, 802.11b, mobile phones and WiMAX. A node with multiple interfaces has the possibility to utilize the multiple network accesses for robust and effcient ...

While reactive routing protocols such as AODV operate efficiently for small ad hoc wireless networks, their O(N) perflow control overhead limits deployment on larger-scale networks. Deployment of compact routing protocols such as geographic routing have ...

Ad hoc networks and peer-to-peer systems typically require many users to participate, in order to leverage the full benefits of the system. In this paper we examine an electronic coupon system, where providers send out coupons, which are passed from ...

In this poster, we introduce our Bluespots project, in which a small computer on a bus serves as a Bluetooth Content Distribution (BCD) station in a university public transit scenario.

Common information dissemination through multihop broadcasting is a key application in many wireless network operations. In all such applications the data transmission rate of broadcast plays a vital role in determining network performance. In this ...

The bandwidth limitation, node mobility, and multi-access interference characteristics of mobile ad hoc networks (MANETs) pose unique challenges to deploying a DHT in MANETs. Previously, we proposed Ekta, a DHT protocol for MANETs that seamlessly ...

Recently, Distributed Hash Tables (DHT) explicitly designed for the use in MANETs have been proposed. Thus, many DHT-based distributed network applications from the domain of the Internet can be expected to be efficiently ported to MANETs. While the ...
