PIS: A Practical Incentive System for Multihop Wireless Networks

Practical Incentive Techniques for Wireless Community Networks

In metropolitan areas, public infrastructures for high-speed wireless networking can be built through the private contributions of individual “micro-operators” who use their Internet-connected Wireless LANs (WLANs) to forward foreign traffic from and to nearby low-mobility clients. We have designed a practical WLAN aggregation scheme that (1) assumes that micro-operators are selfish and do not ...

Security for Multihop Wireless Networks

A Prototyping Environment for Wireless Multihop Networks

Relative to the impressive number of proposals addressing the multitude of challenges raised by IEEE 802.11-based wireless networks, few have known real implementation. In wireless networks, due especially to the unpredictable nature of the wireless channel, bridging theory and practice is far from trivial. In this paper, we advocate including prototyping in the design process of wireless proto...

Scheduling Algorithms for TDMA Wireless Multihop Networks

Scheduling Algorithms for TDMA Wireless Multihop Networks Petar Djukic Doctor of Philosophy Graduate Department of Electrical and Computer Engineering University of Toronto 2008 Current and future wireless standards use TDMA to provide guaranteed Quality-ofService (QoS) in the network. While these standards specify how transmissions should occur, they do not discuss scheduling algorithms to fin...

Code Design for Multihop Wireless Relay Networks

We consider a wireless relay network, where a transmitter node communicates with a receiver node with the help of relay nodes. Most coding strategies considered so far assume that the relay nodes are used for one hop. We address the problem of code design when relay nodes may be used for more than one hop. We consider as a protocol a more elaborated version of amplify-andforward, called distrib...
