Transmission energy consumption is the largest proportion in the energy consumption of wireless body area network（WBAN） and the core of reducing it is to solve two problems: one is which node will be used to transmit when the transmission time slot comes; the other is transmission power of the selected node. For the first problem

to overcome that the existing scheduling algorithms ignore the fairness of the network

a distributed scheduling algorithm with fairness index is proposed. For the second problem

to overcome limitation that the current power control algorithms which use fixed function model

a transmission power control algorithm

which can dynamically adjust transmission power by using the PIDNN control algorithm with self-learning

SPIDNN is proposed. Simulation results show that compared with other schemes

the proposed scheme reduces the energy consumption under the premise of ensuring the fairness of the network.
