MAC protocols

After introducing some different MAC protocols in this thesis,and analyzing energy factors of MAC layer,such as overhearing,idle listening,collision conflict and excessive information of control.For the above reasons,this thesis purposes a cluster structure of energy-efficient MAC layer algorithm(MEAC),this algorithm aims to save energy of the MAC layer,and every aspect of men's nike shoes cluster structure adopts corresponding strategy to reduce the energy consumption of MAC layer.MEAC algorithm used DCHS cluster-head selection to balance networks energy chi hair straighteners consumption,in a stable stage of networks,time slots are dynamically allocated to sensor nodes to avoid overhearing and idle listening issues,and the thesis introduces data weighting coefficient to increase the time slot length of sensitive data.Then, lossless aggregation strategy is used to handle the data that clustering nodes need to transmit,in order to reduce control information and other Lacoste Polo redundant data.Using NS2 simulation platform verify MEAC algorithm various parts,the cheap evening dresses result shows that MEAC algorithm reduces energy consumption,and reaches the goal of plus size wedding dresses energy efficient.Finally,this thesis gives a summary and prospect that the works have been carried out and to be carried out in the future.
