Due to the energy constraint of the sensors, how to employ energy efficiently has become a primary challenge for wireless sensor networks. The network topology design and routing selection play important role in sensors' energy consumption for data gathering. Aiming at the inadequate energy utilization issue brought by the unbalanced traffic load and energy custom made prom dresses consumption over the network, this thesis focuses on improving energy sell discount wedding dresses efficiency by developing a clustering scheme and a layered routing protocol. The main cheap nike shoes works are as follows:Firstly, to solve the energy waste problem caused by the cheap men's nike shoes unbalanced energy employment, a distributed dynamic clustering scheme (DDCS) based on power proportion is proposed. Taking the power proportion among different clusters as a constraint, DDCS predefines an expected clustering distribution model, and the energy in different clusters is expected to be used up chi pink dazzle simultaneously. When clustering, sensors organize themselves into corresponding clusters by comparing their location with parameters of the proposed model by individual decision, and then compete for the cluster head role based on the assessments for their residual energy and locations.
