Designing Interference based Routing Metric In Wireless Mesh Network and Comparison According to Various Tunable Parameters

چکیده
Achieving good performance in wireless mesh network (WMN), implementation of routing metrics is very important. Multiple channels among the multiple radio improve the capacity of the network. Interference based routing metric such as Weighted Cumulative Expected Transmission Time (WCETT), Weighted Cumulative Consecutive Expected Transmission Time (WCCETT), are being proposed in multi-channel multi-hop wireless mesh networks. In this paper we proposed a new interference based routing metric called Modified Weighted Cumulative Consecutive Expected Transmission Time (ModWCCETT) with respect to the selection of less interference path with more channel availability in wireless mesh network. The theoretic analysis and calculations verify the better performance with respect to the other routing metrics.
