Fault Tolerant Hierarchical Multicast Routing Protocol (FTHMRP)
چکیده
Abstract
Mobile Ad-Hoc Network is widely used network. It has many applications like military applications, search and rescue operations, conferences, law enforcement, etc. Most of these applications use multicasting protocol in Mobile Ad-Hoc Network (MANET). Initially Conventional flat multicasting protocols were used. A team affinity model has been used in this protocol wherein the multicast tree consists of teams, rather than individual nodes, and proved scalable and efficient for large scale mobile ad hoc networks. But it has some drawbacks (i.e.) Conventional flat multicasting protocols does not scale well to network size and are not suitable for team multicasting in large scale mobile ad hoc networks. In order to overcome these key problems of scalability to large membership as well as network size and fault tolerance to link/node failures. We propose a new protocol namely Fault Tolerant Hierarchical Multicast Routing Protocol (denoted as FTHMRP) which aims to develop a hierarchical multicast routing protocol based on hypercube architecture for team multicast with fault tolerance. FTHMRP constructs a hierarchy of team leaders and provides fault tolerant multicasting for data sensitive large scale mobile ad hoc networks. Simulation study shows that, FTHMRP provides efficient and reliable multicast compared with the application of a flat multicast scheme (ODMRP) that does not exploit team coordinated motion.
