Every follower uses directional antennas to relay a communication radio and to estimate the location of the leader robot as a sensory device.
In the past, credit-card traffickers did business in private chat rooms on the Internet Relay Chat, a communication network, and now they also use the World Wide Web, where it is easy to start and shut down sites to avoid detection.
In [29], the authors presented a joint relay selection and power allocation scheme for one-way AF relayed D2D communication.
Yomo and Carvalho [5] discuss the spectral efficiency improvement of the cellular system where two mobile subscribers uplink their respective data to base station (BS) while an AF relay facilitates communication to a shadowed subscriber.
In such study, it was found that the use of relays to assist a communication with the objective of increasing its capacity is only effective in high path-loss scenarios, because of the half-duplex constraint of RA schemes.
In this paper, it is demonstrated that entire spectrum of fault resistances can be covered by using the proposed local measurement based directional ROCOV relay in parallel with a communication assisted two-end ROCOV relay.
Like a satellite, the blimps would be able to relay radio communication signals.
In this work, we consider quantized state measurements relayed to a controller via a communication network adopting the standard network coding model.
We consider a two-hop interference MIMO relay communication system where K source-destination pairs communicate simultaneously with the aid of a network of L-distributed relay nodes as shown in Figure 1.
2001 Mars Odyssey, U.S. spacecraft that studied Mars from orbit and served as a communication relay for the Mars Exploration Rovers and Phoenix.
If Maven does not launch this year, the next chance would be in 2016, and a less favorable configuration of orbits means that it would have to expend more fuel to get to Mars, diminishing its worth as a communication relay.
