The Resilient Packet Ring IEEE 802.17 is an evolving standard for the construction of Local and Metropolitan Area Networks. The RPR protocol scales to the demands of future packet ...
In energy constrained wireless sensor networks, energy conservation techniques are to be applied in order to maximize the system lifetime. We tackle the problem of increasing netw...
The problem of transmit beamforming to multiple cochannel multicast groups is considered, when the channel state is known at the transmitter and from two viewpoints: minimizing tot...
