Abstract: A wireless network (20) with at least a first radio communication unit (24) and a second radio communication unit (26) transmits and receives signals with minimal interference from the surrounding environment of the first unit (24) and second unit (26). The first radio communication unit (24) determines frequencies (54) having power level above a threshold (52), and creates a list of these frequencies (50) to be transmitted to the second radio communication unit (26). The second radio communication unit (26) places notches (140) in its transmission band (88) based on frequencies (54) in the list (50), reserved frequencies (132), and local frequencies (92) having signal energy above a threshold (90). When transmitting a signal (42), the second radio communication unit (26) avoids transmitting in frequencies that have notches (140).

Abstract: The present invention provides a network connectivity system and method that facilitate the design of a network connectivity plan where the availability of link resources is limited and varies with the time. The preferred system and methods can be used to provide a network connection plan that fully connects such a network, where possible, while efficiently allocating the link resources used to implement the network connection plan. The network connectivity system and method develops the network connection plan by choosing links based on link resource availability and link duration. Thus, the network connectivity system and method creates a connection plan that, if possible, keeps full connectivity in the network, compensating for changes over time in the availability of links. The network connectivity system thus provides the ability to efficiently connect dynamic networks in a way that facilitates the routing of data to between nodes in the communication network.
