Differential Modulation and Non-Coherent Detection in Wireless Relay Networks

The technique of cooperative communications is finding its way in the next generations of many wireless communication applications. Due to the distributed nature of cooperative networks, acquiring fading channels information for coherent detection is more challenging than in the traditional point-to-point communications. To bypass the requirement of channel information, differential modulation ...

Wireless Mesh and Relay Networks

The paper considers the newest trends in wireless networks based on the Mesh and Relay systems. The basic idea is to perform date transmission via intermediate relay stations and thus range extension and higher throughput can be achieved. The article further introduces IEEE 802.11s and IEEE 802.16j standards that are at the present time in the process of standardization. These standards propose...

Relay Secrecy in Wireless Networks with Eavesdropper

Anonymous monitoring of transmissions in a wireless network by eavesdroppers can provide critical information about the data flows in the network. It is, therefore, necessary to design network protocols that maintain secrecy of routes from eavesdroppers. In this work, we present a mathematical formulation of route secrecy when eavesdroppers observe transmission epochs of nodes. We propose a sch...

Relay-aided Interference Alignment in Wireless Networks

Resource management in wireless networks is one of the key factors in maximizing the overall throughput. Contrary to popular belief, dividing the resources in a dense network does not yield the best results. A method that has been developed recently shares the spectrum amongst all the users in such a way that each node can potentially utilize about half of all the available resources. This new ...
