Presenting a multicast routing protocol for enhanced efficiency in mobile ad-hoc networks

The Mobile Ad-hoc Networks consist of wireless mobile nodes without any pre-determined structure of the network. Routing in this network include important challenges such as changes topology, energy, density of traffic. Due to the limitation of the network resources, multicast routing is an effective method to reduce the network resource consumption. Because Send a copy of the same data to multiple destinations in multiple broadcast method is better than data transmission using a single broadcast to each of the target groups. Due of the lack of a fixed infrastructure in these networks and due to lack of pre-defined physical backbone, a virtual backbone can be formed.Topics proposed algorithms in multicast mesh and tree-based holding virtual backbone, has created a way to send multicast message And proceeded to send a multicast to the group. Some ofThis paper examines the ability of learning automata model to solve the routing problem and increase the network lifetime by using energy parameters and mobility. In proposed method first build connected dominating set (CDS) as a virtual backbone, based on learning automata which this backbone is created based on energy and link stability. In continue proposed algorithm is compared with several protocols, such as ODMRP and MAODV-based broadcast and the delay time which the results show the superiority of this protocol is compared to other protocols.
