Mobile Ad Hoc Networks (MANETs) are a self organizing and adaptive wireless networks. Currently MANETs possess an advanced challenge in providing Quality of Service( QoS) support for real time application data streaming through the network. These applications are delay sensitive and get affected due to congestion in the network. Thus, performance degrades due to high data loss, frequent link breakage and excessive retransmission. The strict layered network structure makes even more difficult to provide solutions for such issues. We propose a protocol which cooperates between adjacent layers and performs cross layer communication. We propose a novel QoS routing for MANET called Cross Layer Best effort QoS aware routing protocol (CLBQ) which considers the metric of link quality, data rates and MAC delay as the QoS parameters. The proposed protocol implements cross layer interaction between PHY, MAC and Network layer. The simulation results conducted shows best effort QoS service to the network in discovering the route and data transfer. Our analysis shows that the protocol has improved throughput and low network overhead. |
