Power control techniques in wireless network for reducing mobile nodes' power consumption and achieving lower signal-to-interference ratio are disclosed. The proposed power control scheme for distributed networks discloses a method for adapting and storing the power level for transmission between the nodes. For each node that communicates with other nodes in the network the power level is calculated and stored in the node's memory (power cache). Each node continuously builds up its power cache. The calculation of the required transmission power level is done either at the receiving node or at the transmitting node. The resulting calculated power level is stored at the transmitting node for reference and for use in future transmissions.
