Medium access control(MAC)protocol is of paramount importance for energy efficiency in wireless sensor networks. An energy efficient MAC protocol SLDMAC is designed for data gathering in linear wireless sensor networks. In order to enhance the performance,when a source node transmits data to the Sink,proper relay nodes are selected for forwarding data according to the energy consumption factor of individual node and residual energy balance factor. Some simulation experiments are conducted and the results show that,SLDMAC provides better energy efficiency and long lifetime than the existing DMAC protocol.
