EEQRPI-MRP: A Quality of Service Based Interference Aware Multipath Routing Protocol for MANETs

Mobile Ad-hoc Networks (MANETs) are widely preferred nowadays due to its ability to connect nodes without specific infrastructure which would be a boon to adverse communication devices. Most researchers work is hard to suggest efficient multipath routing protocols. The proposed work is extended from interference-aware expected transmission time routing (IAEETR) with multipath routing. This paper proposes a standard multipath routing protocol named Energy Efficient Quality of Service Routing Scheme to Predict Interference-Multipath Routing Protocol (EEQRPI-MRP) to attain better quality of service in terms of: energy consumption, packet delivery ratio, packet drop, end to end delay and throughput. The proposed multipath routing protocol is compared with other existing protocols such as: Ad-hoc On Demand Distance Vector (AODV), Near Optimal Radio Interference Aware Multipath routing Protocol (NICE-MRP), Efficient Stable Disjoint Multipath Routing Protocol (ESDMR) and Interference Aware Expected Transmission Time Routing (IAEETR). The efficiency of the proposed protocol is evaluated using NS2 simulator. The result shows 58% improvement in predicting optimized routing path and 65% improvement in interference avoidance compared to existing approaches.
