Bandwidth optimized multicast routing algorithm based on hybrid mesh and tree structure with collision control in MANET using lempel-ziv-oberhumer method

摘要

Mobile Ad hoc Networks (MANETs) shows a vital role for temporary and quick communication. The two routing protocols such as tree-based and mesh-based protocol provides the guarantee and successful delivery. Because of the existence of only one link between two nodes Tree-based gives low bandwidth consumption, high forwarding efficiency. A tree-based multicast routing protocol is best suitable for lightweight ad hoc networks. The QoS (Quality of Service) and performance is degraded when the load of network increases. By coalescing the benefits of the tree structure and mesh structure the effect of network load can be improved. To improve the efficiency and packet delivery ratio congestion control mechanism is introduced by transmitting the compressed data packet. This results in enhanced performance in the network even in dense capacity ad hoc networks. It is experiential that the planned scheme can attain high packet delivery ratio than the existing system.
