摘要
Abstract
For disaster characteristics and rescue operation requirements in emergency circumstances, a mobile node access and directed diffusion route method of wireless sensor networks is proposed. First,a mobile node access and link maintenance mechanism based on the competitive medium access control(MAC)protocol is designed to improve the interest diffusion algorithm and interest encapsula-tion of the directed diffusion (DD)agreement.Then,based on the decision rule for effective paths of interest propagation,dynamic links are built and maintained.The simulation results show that the mo-bile node access method has high efficiency.The access mechanism exhibits advantages in node ener-gy consumption,signal transmission delay and network throughput.The directed diffusion routing al-gorithm based on the decision rule for effective paths of interest propagation can only accurately spread in interest within the local network.The number of the forwarded interest packets is small,and with the increase in the total number of sensor nodes,the variation of the number is small.关键词
