... proposed in order to handle these benefits [3]. In this work, we are interested in elaborating smart signaling schemes for MIMO ad hoc networks. Generally speaking, the transmission strategies with MIMO ... are addressed in three communication systems: point-to-point MIMO communication, cellular MIMO communication, and MIMO ad hoc networks or more generally MIMO...

... which includes the exchanging of control channel messages usually needs four time slots in traditional relaying schemes since all involved nodes operate in half-duplex mode, resulting in significant ... as a reinforcement learning problem [14]. In this section, we briefly explain the reinforcement learning agent in the Network Coding based Intercluster Connection, and then we present...

First, each fork maintains its ... priority counts incoming and outgoing data arcs connected to any nodes in sibling subgraphs. It is the total number of incoming data arcs minus the number of outgoing data arcs. Finally, a n...

Unfortunately, it was shown that certain theorems involving Dhage’s D-metric spaces are ... for each n ∈ N. An interesting fact about maps satisfying property P is that they have no nontrivial periodic points. Papers dealing with property P are those in 12–14. In this paper,...
