High Throughput Multirouting in the Wireless network with path Metric computation

Abstract: Many applications and areas of wireless sensor networks (WSN), have diverse data traffic with different quality of service (QOS) requirements. As ddress the problem in this paper by Employing a High Throughput Metric (HTM), which finds high-throughput paths on multi-hop wireless networks. HTM minimizes the expected total number of packet transmissions (including retransmissions) required to successfully deliver a packet to the ultimate destination. In contrast, the minimum hop-count metric chooses arbitrarily among the different paths of the same minimum length, regardless of the often large differences in throughput among those paths, and ignoring the possibility that a longer path might offer higher throughput. This paper describes the design and implementation of HTM as a metric for the routing protocols. Experimental results demonstrate for long paths the throughput improvement is often a factor of two or more, suggesting that HTM will become more useful as networks grow larger and paths become longer.
