In order to reduce energy consumption of nodes and improve energy utilization

a reprogramming protocol based on the minimum node degree transmission power control（MND—TPC）

which has a highly efficient energy-saving with the minimum node degree

is presented.Firstly

the protocol initialize the network considering the rest energy and maximum transmission power of each node

besides node degree and link quality

then

the process of data-transmission is departed into two stages.During the first stage

through node density

node degree

and percentage of M-degree nodes and another factors

to generate adjustment model of transmission range

as a result

high efficient optimized network can be built; in the second stage

the network choose the delivery node by comparing transmission power and remaining energy

to ensure uniform distribution of load of network and effective implementation of energy-efficient

thus prolong the life cycle of the whole network.Theoretical analysis and experimental results show that comparing with MNP protocol

the proposed protocol can reduce the energy consumption at least 35.48 % in average under different transmission power.
