Other AbstractApplication features such as non-equilibrium traffic and local intensive topology and application requirements such as low energy consumption and high real-time communication make a challenge to MAC protocol design in the transmission line monitoring. Aiming at the deficiency of original X-MAC protocol used in the transmission line monitoring network during low-flow periods,SX-MAC protocol is designed through introducing synchronization and estimating waking up time accurately. SX-MAC can reduce the length of preamble packets and save energy to the maximum. The network energy consumption is analyzed,and thetheoretical value of optimal synchronization period is deduced. And duty cycle staggered scheduling mechanism is proposed to optimize real-time of upstream data. OPNET is used to emulate the performance of SX-MAC,and the results show that makes significant improvement than X-MAC both in energy efficient and real-time in this scenario. The optimal synchronization period is 15 min under the simulation conditions.
