| 摘 要： | 在节点移动规律无法预知、连通性较差的机会网络中,FIMF(Ferry-Initialed Message Ferrying)路由能够有效地提高网络中消息传递成功率.在FIMF路由机制中,普通节点在传递控制消息(如节点位置消息、Hello消息)时存在多余的通信开销,并且采用了大功率发送位置消息会耗费过多能量.提出了基于RSSI测距技术和跨层设计的消息摆渡节能路由算法AFIMF.AFIMF中采用基于RSSI测距技术,在普通节点上采用自适应调整功率技术和跨层检测技术按需发送Hello消息.仿真结果表明,AFIMF算法有良好的稳定性,在保证通信传递率的前提下,普通节点不仅有效地节约了能量,而且减少了开销. |

| Abstract: | In opportunistic networks, it is difficult to know in advance how a node moves and holds a poor connectivity. It has been shown that using Ferry-Initialed Message Ferrying (FIMF) scheme can effectively improve the network message delivery success rate. This paper describes a system for the analysis of the FIMF and gives an advanced algorithm called AFIMF. The algorithm uses the RSSI technology to reduce the transmit power of the node location messages. Besides, it is based on cross-layer information sharing to send hello messages of node on-demand. The results show that AFIMF can effectively save energy consumption and reduce network overhead. |
