Code division multiple access (CDMA) Manet

A method for communicating between nodes in a mobile ad hoc network, the method comprising:

• a first node in a mobile ad hoc network communicating with a second node in the mobile ad hoc network using both code division multiple access (CDMA) and frequency division duplexing (FDD);
• coding the communication on the first node prior to transmission to the second node, wherein the coding includes applying DSSS modulation to a transmission signal at a specified bit rate over a specified spectrum, the DSSS coding being applied in accordance with a processing gain which spreads the spectrum relative to the bit rate of the transmission;
• transmitting the coded communication over a specified frequency band allocated to the first node using FDD over which the first node transmits data and over which the second node receives the data
• receiving, on a receiving band, a CDMA signal;
• determining a broadcasting power level associated with the received CDMA signal;
• and
• determining whether the received CDMA signal will interfere with other nodes in the mobile ad hoc network.

A method for communicating between nodes in a mobile ad hoc network that includes a plurality of nodes, the method comprising:

• determining that one or more portions of data are to be part of a communication sent from a first node in the plurality of nodes to a second node in the plurality of nodes using all of code division multiple access (CDMA), frequency division duplexing (FDD), and time division multiplexing (TDM);
• based on the determination, coding the communication on the first node prior to transmission to the second node, the coding including applying DSSS modulation to a transmission signal at a specified bit rate over a specified spectrum, the DSSS coding being applied in accordance with a processing gain which spreads the spectrum relative to the bit rate of the transmission;
• transmitting the communication using time division multiplexing (TDM) over a specified frequency band allocated to the first node over which the first node transmits data and over which the second node and at least a third node receives the data;
• and
• wherein the first node receives one or more asynchronous transmissions from other nodes in the plurality of nodes, the nodes comprising the N strongest neighbor nodes.
