Data communication technology in wireless sensor networks using Bluetooth is studied

and a fast and energy efficient Bluetooth scatternet formation algorithm is presented to construct the network.An energy aware routing scheme is used to balance the power consumption rate of each node

and the timing wake-up and multiple working states transition mechanism are presented to prolong the node lifetime.Simulated experiments and theoretical analysis demonstrate that the scheme can reduce power consumption of the network and prolong the lifetime of the whole network.
