In Wireless Sensor Networks sensor nodes plays a major role in determining the network lifetime considering energy as a limited resource. Since WSNs are deployed in large numbers in many remote locations and unattended areas, adhoc transmissions act as a key component which in need to consider various parameters in wireless sensor applications and protocols. Increase in lifespan, robustness, fault tolerance, and self-configuration are the major parameters. Enhanced Energy Efficient Routing Protocol (EEE-RP) is the preceding protocol introduced for energy efficiency and data forwarding. On the other hand, adequate methodology for route selection is necessary for efficient packet delivery. Here, the protocol only considers data forwarding, and it does not optimize the ideal path for maximum packet delivery ratio. Hence there exists a necessity of energy efficient route optimization and data forwarding technique to forward the data from source to destination. To overcome the route optimization issues, Nature inspired QoS enabled Water Cycle Algorithm based Protocol (QoS-WCAP) is proposed in order to optimize the route by sharing the communication among the water drops which enhances the quality of service. Multi-hop routing technique is utilized to exchange the data between the clusters and transfers to Base Station (BS). Roulette Wheel Selection and Pareto based Investigation methods are employed to find the finest path for efficient data forwarding in optimized manner to minimize the energy. All the tests are carried out by NS2.35 simulator. Simulation results indicated that QoS-WCAP performs better in terms of energy consumption, delay, packet delivery ratio, and failure tolerance level and network lifetime.
