| 抄録(英) | Multi-hop wireless networks are considered promising for the next-generation communication systems because of their wide applicability to hard-to-wire circumstances, especially in natural disaster recoveries and military operations. However, the throughput of multi-hop wireless networks based on the widely accepted IEEE 802.11 DCF is so low due to inter-flow and intra-flow collisions that further applications of the networks are limited. In our previous paper, a minimal modification of IEEE 802.11 DCF is proposed for improving significantly the throughput of the networks by realizing efficient synchronization among multiple hops. The protocol is named Synchronized Multi-Hop Protocol. In this paper, the proposed protocol SMHP is extended to achieve high throughput in the cases where there are transmission failures and the interference range is much wider than the transmission range. By theoretical analysis and simulation experiments for the comparison with existing protocols, the proposed extension of SMHP is proved to be optimized in terms of the throughput of the network especially in situations with rather high packet transmission error rate and large interference range. |
