Design and Simulation of High Performance High Pass Filter at 45 Nm Technology Node

Abstract: Wireless Mesh Networks (WMNs) have recently attained lot of popularity due to their rapid development and instant communication capability. The two factors that influence the performance of wireless routing are routing metrics and routing algorithms. Most of these metrics are designed using cross layer approach for specific type of mesh networks. Therefore there is a need for evaluating the performance of these routing metrics in infrastructure WMN. In this paper we study and evaluate the performance of three cross layer routing metrics of OLSR (optimized link state routing protocol) using NS-2. The routing metrics that we compare include Expected Transmission Count (ETX), Contention Aware Transmission Time (CATT) and Metric for Interference and Channel Switching (MIND). The results show that MIND and CATT improves the throughput and decreases the delay. However, ETX performance is poor compared to other metrics.
