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. To combat the


above limitations, an Extremely Opportunistic Routing(ExOR) scheme with Expected Transmission


count(ETX) metric is proposed and implemented in a hybrid scenario. The simulation study reveals that


this routing technique efficiently utilizes resources and improves the end-to-end throughput and packet


delivery ratio in hybrid wireless networks.
