1. An input/output device comprising:
- a transmitter configured to generate a radio frequency signal transmission;
a receiver configured to receive a radio frequency signal transmission from a plurality of separately provided input/output devices arranged in a multi-signal path transmission network; and
a processor-based control coordinating transmissions of radio frequency signal transmissions from at least one of the plurality of separately provided input/output devices, the processor-based control configured to;
receive a route request from at least one of the plurality of separately provided input/output devices, the route request including a destination for a proposed communication over the network;
determine whether the receiver is the destination for the proposed communication, and, if so, generate and transmit a route reply message without delay; and
if the receiver is not the destination for the proposed communication, determine whether a signal path to the destination through another of the plurality of separately provided input/output devices to the destination is available, and if a signal path to the destination is available, generate and transmit a route reply message after at least a first predetermined amount of delay.

Abstract
Devices, networks, systems and methods for coordinating industrial control and monitoring communications on multi-path radio frequency transmission mesh networks include establishing path metrics allowing a respective comparison of a plurality of available communication paths between neighboring radios communicating in the mesh network. Replies to route requests may be delayed based on the path metrics of available paths for message transmission to ensure that the best available connection routes through the mesh network can be understood and utilized.
