Performance evaluation of new hybrid multicast routing protocols for ad-hoc networks
Lei Chen, Adel Ben Mnaouer · 2004
In this paper, we investigate two new hybrid protocols obtained by combination of proactive and reactive behaviors of other two well-known multicast routing protocols, namely the ODMRP and the MAODY. Hybrid routing protocols are known to perfonn better then either pure reactive or proactive protocols in the sense that they 1Iy to strike a balance between improved delay perfonnance and lower ovemead activities. In this work we combine the zone routing proactive behavior of the ZRP protocol with the reactive behavior of the ODMRP and MAODV protocols. The new protocols are named ZMAODV and WDMRP. Using Glomosim simulation we evaluate the perfonnance of these protocols and compare them to their original counte1parts as well as to the Multicast Zone Routing Protocol (MZR). The results reveal that the ZODMRP perfonns the best while the MZR exhibits the worst perfonnance.
