A system and method for calculating a routing metric that can select the route providing the best throughput in a multihopping network (100), based on one or more parameters including completion rates, data rates, MAC overhead and congestion. The system and method are capable of selecting a route in a multihopping network (100) having a high throughput, comprising calculating a routing metric at one or more nodes (102, 106, 107), wherein the routing metric enables the one or more nodes (102, 106, 107) to select the route in the network (100). The routing metric can include network information such as the raw data rate, the completion rate, and the media access control overhead and congestion.
