Graphical Abstract:


Background: MANET is a constrained environment having limited energy, restricted bandwidth, and unstable wireless connectivity, etc. It creates a high demand to design an efficient QoS routing protocol having a multi-criteria metric to make efficient routing decisions.

Aim: The main aim of QoS based routing protocol EB-OLSR (Energy efficient and Bandwidth aware Optimized Link State Routing) is to achieve enhanced aggregate network throughput. Which is acquired by selecting QoS qualified efficient nodes to transmit data packets. EB-OLSR set out analogous efficient mobile nodes for routing by applying newly defined multi-criteria metric EPNI (Efficiency Parameters for Node Indexing) which estimates the node’s efficiency index on the basis of four QoS parameters that are unconsumed power, slothful period, queue length and residual bandwidth.

Methods: We obtained a single node index for each mobile node through EPNI metric based on residual battery, node idle time, packet queue length and residual bandwidth.

Results: EB-OLSR produced aggregate network throughput enhancement of 574 bits per second in comparison of MP-OLSR and 390.66 bits per second in comparison to MBQA-OLSR. Average End-to-End Delay for EB-OLSR is 0.41, 0.16 times less and Packet Delivery Ratio enhances 30.74%, 9.5% respectively.

Conclusion: Experimental results proved that the EB-OLSR is an energy-efficient and bandwidth aware optimized link-state routing protocol, which successfully meets the main aim of this study i.e. throughput enhancement of mobile ad-hoc network. The EPNI metric is the major strength of the work which is used to get a single-valued weighted sum of multiple criteria.

Keywords: Mobile ad-hoc network, QoS, routing protocol, available bandwidth, residual energy, signal strength, MP-OLSR, MBQA-OLSR, EB-OLSR.
