An efficient multicast hybrid routing protocol for MANETs

Abstract

Multicasting reduces communication cost for applications which need to send same data packets to multiple destinations instead of sending via multiple unicasts. It also reduces the required channel bandwidth, sender and router processing and delivery delay. This paper compares the performance of an efficient multicast hybrid routing protocol with the existing one. i.e. MAODV. We explore the reliability as well as proactive approaches of Multicast Hybrid Distance Vector (MHDV) for MANETs, which are used to improve the Packet Delivery Ratio (PDR) in all possible mobility rates as compared with MAODV. It is also observed that, the PDR and end-to-end delay of proposed routing protocol are better for less number of senders. © 2010 Springer-Verlag Berlin Heidelberg.
