ETX Metric for Extremely Opportunistic Routing to Improve the Performance of Hybrid Wireless Networks
Mobility in wireless networks has paved way for a new paradigm of communication in this era. Exploiting the optimal routing technique for hybrid wireless networks which brings in a balance of the overheads in infrastructure based and infrastructure less network is essential. Routing protocol design for hybrid wireless network is critical in order to improve the performance and reliability of the network. Opportunistic Routing (OR) technique attempts to deal with unreliable transmissions by utilizing the broadcast nature of the wireless medium. Due to multi-hop nature of ad hoc networks, Opportunistic Routing provides lesser throughput than expected when minimum hop count metric is used.
