Efficient path estimation routing protocol for QoS in long distance MANETs

Due to increased adoption of digital consumer services, Mobile Ad-hoc Networks (MANETs) are gaining importance in real-life business applications. MANETs are wireless networks consisting of a set of mobile nodes and enables multi-hop peer-to-peer routing without any requirement of predefined infrastructure for its deployment. There are several works in literature for improving the Quality of Service (QoS) such as BRAWN, AODV and DSDV. However, these approaches have to be augmented with additional parameters mainly to avoid congestion and propagation delays. In this paper, we present an improved protocol to maintain higher QoS in MANETS by determining multiple efficient paths and ranking them. In addition to Bandwidth and Data rate, we also incorporate additional parameters namely Queuing delay and Distance in order to dynamically compute the paths for a specific communication with minimum delay. We demonstrate the viability of our proposed protocol with an example.
