Improving end-to-end throughput is the main application in multi hop wireless networks. This is the one of the major challenges. Traditional multi hop routing protocols are designed for having the least hop count for an end-to-end connection. This reduces the contending parties that have to share the upper-bounded bandwidth and, therefore, improves the throughput. The examples are the mobile ad hoc networks (MANET), which select a route with the smallest hop count and it will reducing the end-to-end throughput because more nodes have to be included in the routes. The available data rate and the number of active nodes are two conflicting factors that affect network throughput. To improve throughput by selecting routes according to metrics other than hop counts. In this paper, we first analyze the impact of link distance on end-to-end throughput in wireless networks. From the analysis the simulation results show that changing the link distance affects the change in the network throughput. To achieve a high network throughput, a proper link distance (i.e. load density) is required for each hop. According to the load density, ASR can help improve the network performance by adjusting the link distance in the routes.
