We consider the problem of mitigating interference and improving network capacity in wireless multi-hop networks. An ongoing aim of our research is to design a routing metric which is cognizant of interference. To address this issue, and based on the measurement of the received signal strengths, we propose a 2-Hop interference Estimation AlgoRithm (2-HEAR). With the use of the received signal level, a node can calculate the signal to interference plus noise ratio (SINR) of the links to its neighbors. The calculated SINR is used to infer the packet error rate (PER) between a node and each of its first tier interfering nodes set. Then, the residual capacity at a given node is estimated using the calculated PERs. Based on the capacity estimation analysis, a new routing metric, EBC (Estimated Balanced Capacity), is proposed. EBC uses a cost function at the aim of load-balancing between the different flows within the network. Extensive simulations shows that EBC improves tremendously the network capacity and also enhances the VoIP calls quality.
