Abstract

We measure and evaluate the capacity of an asymmetric multi-hop wireless ad hoc network from a new perspective using minimum impact routing, which selects a route based on total interference impact measured with total disturbed nodes along an asymmetrical transmission path. Wireless nodes use this local interference measure as the threshold to adjust the variable transmit power in order to achieve optimal number of relays and spatial reuse, hence reducing the impact of multi-hop interference and relaying on capacity. Our result shows minimum impact routing coupled with variable transmit power that optimizing spatial reuse has a significant reduction in total disturbed nodes compared with shortest-path routing, furthermore a dramatic impact on network capacity performance
