Abstract
We present the design and development of a new multicast routing protocol, referred to as the Multicast Link Distance Ratio (MLDR) routing protocol, which yields stable trees with longer lifetime and without incurring any substantial increase in the number of edges and the hop count per source-receiver path. The proposed multicast protocol is based on the idea of assigning each link a weight, called the Link Distance Ratio (LDR), corresponding to the ratio of the actual physical Euclidean distance between the constituent nodes of the link to that of the maximum transmission range per node. The multicast tree construction procedure of MLDR focuses on discovering source-receiver paths that have the lowest sum of the LDR values of the constituent links. An aggregate of all such source-receiver paths yields the MLDR multicast tree. The lifetime of MLDR multicast trees is 25% - 63% longer than that of the well-known minimum hop based Multicast Ad hoc On demand Distance Vector (MAODV) routing protocol and at the same time the number of edges per tree and hop count per source-receiver path are slightly larger than that of MAODV, by factors of 11% and 8% respectively.
