Method for automatic signal routing in ad hoc networks
First Claim
Patent Images
1. A method for routing signals through a communications network, the method comprising:
- receiving a signal at an intermediate node;
monitoring, at the intermediate node, a parameter derived from the signal domain and measured by examination of an initial portion of the received signal, the parameter being characteristic of the energetic or physical makeup of the received signal and indicating an extent of prior retransmission of the signal; and
forwarding the received signal from the intermediate node to a second node or a destination receiver only if the intermediate node is a member of a predefined communications pathway between the received signal'"'"'s origination and destination nodes and the parameter associated with the signal satisfies at least one predetermined criterion, the predetermined criterion being selected to ensure that the received signal will only be forwarded if forwarding the signal will enhance reception and decoding of the signal at the destination receiver.

Abstract
A method and system provide routing of signals through a communications network. A transmitted signal is received. The signal has an associated parameter that is monitored as the signal is received. The parameter indicates the extent to which prior retransmission of the signal has occurred. The signal is retransmitted only if its parameter satisfies at least one predetermined criterion.

24. A system for signal routing, comprising:
-
a receiver for receiving a signal at an intermediate node; at least one monitor for monitoring, at the intermediate node, a parameter derived from the signal domain and measured by examination of an initial portion of the signal, the parameter being characteristic of the energetic or physical makeup of the received signal and indicating an extent of prior retransmission; and a transmitter for forwarding a signal from the intermediate node to a second node or a destination receiver only if the intermediate node is a member of a predefined communications pathway between the received signal'"'"'s origination and destination nodes and the parameter associated with the signal satisfies at least one predetermined criterion, the predetermined criterion being selected to ensure that the received signal will only be forwarded if forwarding the signal will enhance reception and decoding of the signal at the destination receiver. - View Dependent Claims (25, 26)
