RECONFIGURABLE ANTENNAS AND CONFIGURATION SELECTION METHODS FOR AD-HOC NETWORKS
First Claim
1. An ad-hoc network system, comprising:
- at least one transmitter and/or receiver having at least one multi-element reconfigurable array of transceivers; and
a processor that processes software implementing a configuration selection method for selecting an antenna configuration for said at least one multi-element reconfigurable array, where the antenna configuration is selected based on changes in interference in a transmission over a transmission link including the antenna being configured, a transmission rate of at least one transmitter, a received signal strength of at least one receiver, an error vector magnitude of at least one receiver, a channel matrix of at least one receiver, and/or a packet error rate of at least one of the receivers or transmitters.

Abstract
Reconfigurable antennas in an ad-hoc network are provided where all nodes employ MIMO/SIMO/MISO communication techniques. Three types of reconfigurable antennas: Reconfigurable Printed Dipole Array (RPDA), Reconfigurable Circular Patch Antenna (RCPA) and Two-Port Reconfigurable CRLH Leaky Wave Antennas are used. The RPDA, RCPA and the CRLH Leaky Wave antennas have a different number of configurations as well as different degrees of pattern diversity between possible configurations. To effectively use these antennas in a network, the performance of centralized and decentralized antenna configuration selection schemes are quantified for reconfiguration at one or both link ends. The sum capacity of the network is used as a metric to quantify the performance of these antennas in measured and simulated network channels.

10. A method for selecting the configuration of at least one multi-element reconfigurable array of transceivers in an ad-hoc network, comprising:
-
a processor selecting an antenna configuration for at least a transmitter and/or a receiver of a transmission link in said ad-hoc network; measuring or estimating interference, a channel matrix, a transmission rate, a received signal strength, an error vector magnitude, and/or an error packet rate of said transmission link; and selecting an antenna configuration for another transmission link in said ad-hoc network based on said measured or estimated interference, channel matrix, transmission rate, received signal strength, error vector magnitude, and/or error packet rate of said transmission link. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
