A Loose Clustering based QoS Aware Routing Protocol for Power Heterogeneous MANETs

Power heterogeneity is common in mobile ad hoc networks (MANETs).With high-power nodes; MANETs can improve network scalability, connectivity, and broadcasting robustness. However, the throughput of power heterogeneous MANETs can be severely impacted by high-power nodes. To address this issue, we present a loose-virtual-clustering-based (LVC) routing protocol for power heterogeneous (LRPH) MANETs. To explore the advantages of high-power nodes, we develop an LVC algorithm to construct a hierarchical network and to eliminate unidirectional links to reduce the interference raised by high-power nodes; we develop routing algorithms to avoid packet forwarding via high-power nodes. Also introduce Quality based service and admission control technique for routing. Quality based service decrease the delay and energy failure. Admission control used to avoid packet loss. Providing quality of service (QoS) assurances in a mobile ad hoc network (MANET) is difficult due to node mobility, contention for channel access, a lack of centralized co-ordination, and the unreliable nature of the wireless channel. A QoS-aware routing (QAR) protocol and an admission control (AC) protocol are two of the most important components of a system attempting to provide QoS guarantees in the face of the above mentioned difficulties faced.
