基于相遇节点跨层感知的机会网络高效低时延路由算法
Efficient low-delay routing algorithm for opportunistic networks based on cross-layer sensing of encountered nodes
摘要
Abstract
An efficient low-delay routing algorithin, name epidemic routing based on cross-layer encountered-node sens-ing (ERCES) was proposed to address the issue that the epidemic-based routing algorithms have some extralatency in sensing encountered nodes and extra overhead in exchanging data packets. ERCES achieves to speed sensing encountered nodes through cross-layer design among the PHY, MAC, and network layers. Moreover, to reduce overhead and to de-crease data latency, it makes a node send novel data packet immediately after encountering other nodes, sends the packets close-by their destinations firstly after receiving summary vector(SV) packets, adaptively varies the period of HELLO packets,and deletes the packets reaching their destinations from nodes’ memory with the help of SVs. Theoretical anal-ysis verifies the effectiveness of ERCES. And simulation results show that ERCES reduces by at least 11.3%the control overhead by at least 8.2%, 2.1% memory overhead by more than 2.1%, and the average end-to-end delay by at least 11.3%.关键词
