A method and apparatus of combating the problem of interference in master-slave time division duplex indoor wireless networks based on standards, such as the Bluetooth&#x2122; standard, is proposed. The method involves a frequency look-ahead scheme in frequency hopping systems, a scheme of monitoring states of master-slave wireless communication links through values recorded in link history counters, and a scheme of scheduling an appropriate slave unit and choosing a suitable packet size to overcome the effect of interfering sources, if any, in the pico-cell.

Frequency look-ahead and link state history based scheduling in indoor wireless pico-cellular networks

A method, system, and computer program product for organizing a set of nodes into a minimum number of connected clusters of bounded size in a wireless transmission system, wherein the method comprises using of bits in packets used in the initial stages of the device discovery procedure, to include information relating to a state of device discovery to achieve the separation of the nodes into those in the transmit-state and the receive-state; defining a Master-designate among the nodes through a statistical procedure and defining remaining nodes as a Slave-designate; defining a cluster including the Master-designate and at least one the Slave-designate, wherein the Slave-designate continuously scans for the inquiry message transmitted from the Master-designate and the Slave-designate transmits the inquiry response to the Master-designate.
