ENHANCED METHOD FOR REDUCING ENERGY CONSUMPTION AND END-TO-END DELAY IN VESSEL STATIONARY WIRELESS SENSOR NETWORK

摘要

PURPOSE: A method for improving the delay time performance improvement and energy efficiency of asynchronous duty-cycle MAC in a vessel sensor network environment is provided to improve a transmission delay time by performing a temporary synchronization method while maintaining the energy efficiency of asynchronous MAC. CONSTITUTION: Energy efficiency is maintained through an SNC(Synchronize on each Neighbor's Cycle) and an STC(Synchronize on Tunneling Cycle) function by using a cross layer method with a network layer. A transmission delay time is improved by performing a temporary synchronization method while maintaining the energy efficiency. QoS(Quality of Service) on a multi hop path is guaranteed.
