Abstract
This paper presents a source based reactive protocol for MANET. It is an enhanced version of our previous protocol called "Power aware multiple QoS constraints routing protocol with mobility prediction (PMQRPMP)". It considers QoS parameters namely delay, jitter, bandwidth, and cost of each link on 'n' available paths and selects 'k' paths with good battery backup between a source and a destination during path discovery. EMIQRPDM checks the bandwidth constraint during route request to minimize control overhead. EMIQRPDM uses our new mobility prediction mechanism to find the link expiration time and determines the stability of link expiration time during route reply. It executes path maintenance procedure when the link between two nodes cuts off. EMIQRPDM also considers a backup path during link failure thus reducing control overhead. It uses an intelligent load distribution algorithm to distribute the load on the selected 'k' routing paths as to increase throughput in MANET.
