| Abstract: | The multiple access interference(MAI) and node interference(NI) are evaluated based on CDMA in wireless sensor network(WSN).The effects of transmission distance,rate,shadowed environment,node density are considered,and the bit error rate(BER) is simulated by Matlab.The simulation results indicate that CDMA can be used for saving energy and reducing interference in physical layer. |
