未来的军事应用需要无线传感器网络（WSN）中的多媒体流来提供高质量的热点信息。最近的工作提出部署由高带宽骨干网络支持的大规模无线传感器网络以实现多媒体流，但由于使用的低速率无线电以及限制吞吐量的无线干扰的影响，无线传感器网络仍然是瓶颈。我们提出了一种干扰最小化多路径路由（I2MR）方案，该方案通过发现最大区域不相交的最短路径来实现负载平衡来提高吞吐量，同时需要最少的本地化支持。此外，我们提出了一种拥塞控制方案，可以减少长期路径拥塞，从而进一步提高吞吐量。我们通过与单路径 AODV 和多路径 NDMR 进行比较来评估具有拥塞控制的 I2MR。结果表明，具有拥塞控制功能的 I2MR 的吞吐量比 AODV 和 NDMR 平均提高了 230% 和 150%，并且消耗的能量与 AODV 相当或最多多 24%，但比 NDMR 减少了 60% 的能量。
Multimedia streaming in Wireless Sensor Network (WSN) is required for future military applications to provide high-quality information of hot spots. Recent works have proposed deploying large-scale WSN supported by high-bandwidth backbone network to enable multimedia streaming, but the WSN remains the bottleneck due to the low-rate radios used and the effects of wireless interferences that limit throughput. We propose an Interference-Minimized Multipath Routing (I2MR) scheme that increases throughput by discovering maximally zone-disjoint shortest paths for load balancing, while requiring minimal localization support. Furthermore, we propose a congestion control scheme that reduces long-term path congestions to further increase throughput. We evaluate I2MR with congestion control by comparing with unipath AODV and multipath NDMR. Results show that I2MR with congestion control achieves on average 230% and 150% gains in throughput over AODV and NDMR, and consumes comparable or at most 24% more energy than AODV but up to 60% less energy than NDMR.
