The phrase "acting as a relay" is correct and usable in written English.
It can be used in contexts where something or someone is serving as an intermediary or facilitator in a process or communication.
Example: "The server is acting as a relay between the client and the database, ensuring that requests are processed efficiently."
Alternatives: "serving as an intermediary" or "functioning as a conduit."
The selected CH leads the network in forwarding the sensor data from its member nodes to the BS, while simultaneously acting as a relay node for the other clusters.
Cooperative communications allow different users in a wireless network to collaborate and share each other's resource; thus, a particular user may transmit data of its own or assist another user through forwarding the received message by acting as a relay.
The idea of opportunistic forwarding is that at each hop, a set of next-hop relay candidates which have successfully received a packet compete for acting as a relay.
Nodes in multi-hop networks (except leaf nodes) have the additional task of acting as a relay for other nodes - therefore, they do not just send messages, but receive messages as well.
For this example, constraint (7) states that data generated at node-3 which is designated to flow on its first routing path transmitted by node-3 (the first hop of the path) can have only one receiver (i.e., there should be only one second hop node, which can be the base station or another node acting as a relay).
Finally, in multiple-tier topologies (more complex than the 3-tier considered in this article), the same approach can be applied to compute the probability of transmission of any node acting as a relay at a given hierarchical level of the network.
Mr. Cook said brief beeps from the rover were picked up Wednesday night by the Mars Global Surveyor, which is orbiting the planet and acting as a communications relay station.
So it came as a shock when Mr. Chung, the waiter acting as a translator, relayed a new request from a doctor: Would they agree to let Mr. Zhao die?
However, metal nanoparticles can catalyze the reaction by acting as an electronic relay agent to transfer electron from NaBH4 to the nitro compounds [32, 34].
Within seconds, they were lost to view with only the GPS tracker (acting as a baton in the relay) showing their location on a large screen.
(2) RTSBC (Request-to-send, borrowed channel): serves the same function as a traditional RTS frame in addition to acting as a signal for the relay and client to switch channels, or to begin the second RDATA transmission.
