Approach for Reducing Control Packets in AODV-Based MANETs
Movements of nodes in MANETs result in route changes, thus requiring the transmission of control packets. As MANETs have limited resources, it is important to reduce the number of...

On the complexity of suboptimal decoding for list and decision feedback schemes
We consider bounded distance list decoding, such that the decoder calculates the list of all codewords within a sphere around the received vector. We analyze the performance and t...
