the design of protocols that treats the multicast large scale reliability in a non-reliable environment such as mesh wireless networks is a challenge for a wide variety of applications, especially when these applications require a short deadline and a high bandwidth. In this paper, we study the performances of two reliable multicast protocols based on active networks: AMRHy(Active Dynamic Replier Reliable Multicast) and DyRAM(Active Multicast Reliable Hybrid). This analysis will allow us to show the contribution of the combination of the class receiver-initiated and sender-initiated, adopted by the protocol AMRHy, in solving the reliability problem involving routers able to execute customized services according to the received packets
