QOSRGA Protocol Using Non-Disjoint Multiple Routes in Mobile Ad Hoc Networks
Author:
Abstract: The problem of QoS Routing for MANET posses several challenges that must be addressed. To select the most optimal route from source to destination, one has to choose from a set of routes with the corresponding quality of connectivity and resources. A rationale for multiple routes is presented. We argued that QoS routing protocol should exploit the rich non-disjoint node connectivity over disjoint paths to improve the source to target(S-T) connectivity lifetime in a MANET. Non-Disjoint Multiple Routes Discovery (NDMRD) protocol is proposed as a method of accumulating these routes, capturing QoS parameters and disseminates them appropriately. QOSRGA (QoS Routing Using GA) is designed to select the best QoS routes based on QoS metrics such as bandwidth, delay and node connectivity index (nci). We outlined the GA process and how its related parameters are chosen. The performances of NDMRD and QOSRGA protocol are presented.
