Due to the growing use of mobile devices, wireless technologies have had a significant development. Common applications for mobile users are video, voice and data, increasing demand for bandwidth.
There are two main types of wireless networks: infrastructure networks and ad hoc networks. In infrastructure networks there is a central coordinator, which is responsible for setting the links between

users of the network and the communication between users is provided through it. In Ad Hoc wireless networks there is no coordinator node, but each node in the network acts as a router. Communications among users are multi-hop.
Infrastructure networks have coverage area delimited by the by the transmission power and the antenna reception gain in the access point. To extend this coverage area, a wireless Ad Hoc can be used. However, it is necessary to tackle with several issues. For example, intercommunication within the mobile ad hoc networks differ from wired networks in the following aspects :
• The wireless channel has variable and unpredictable characteristics. • The available bandwidth and battery power are limited in mobile devices. • Computing have limited capacity and limited processing power. • The mobility of the nodes creates topology changes continuously. • The wireless medium is a means promiscuous, that is, no matter how specific the receiver node,
all nodes within range hear the packages simultaneously.
In recent applications is necessary to merge wireless networks with wired networks. In works such as [2,3,4,5], have extensively studied the integration of these networks using unicast traffic. However for the case of multicast traffic, there are few studies. The multicast approaches are very important in order to save bandwidth, avoiding flood the network with information that not all nodes need, and avoid deliver information to unwished nodes. Multicast operation in hybrid networks are very important issue, because the information can travel across many networks, many architectures and need to be delivered to a group of users efficiently.
For the study of multicast traffic in mobile ad hoc networks have been proposed several mechanisms, one of those protocols is the Multicast operation on Ad-hoc On Demand Distance Vector (MAODV) . In studies like [6,7,8] a comparison of several Ad hoc multicast protocols are made.
Other studies tried to reduce the control traffic in the ad hoc network [9,10,11]. Some other authors deal with problems associated...
