QoS parameters improvement for the hybrid Zone-based Routing Protocol in MANET

A new Virtual Base Station (VBS) election technique is proposed by this paper to help in QoS provisioning in the infrastructure-less Mobile Ad-hoc Networks referred to as MANET. This VBS election technique is based on the mobile node's Signal-to-Noise Ratio (SNR) and has been applied on the MANET's hybrid routing protocol: The Zone-based Routing Protocol. The developed routing protocol will be referred to as SNR-VBS ZRP. Based on the QoS adopted definition special to the MANETs, the performance evaluation metrics will be redefined by the paper. In order to study the impact of the SNR-VBS ZRP on the main QoS metrics, simulation results were derived from the QualNet simulator. Therefore, the SNR-VBS ZRP performance will be compared to the standard ZRP to highlight its effect on QoS provisioning in MANET.
