Multicast routing becomes the most challenging problem in Wireless Sensor Networks (WSN). Multicasting is an effective way to facilitate group communication in which the multicast data need to be sent from a source node to multiple receivers. In this paper, a simple and efficient algorithm Minimum Connected Dominating Set (MCDS) is used to form a virtual backbone as forwarding group of the network. The MCDS aims at minimizing the number of nodes,
where few nodes should be dominated, which are responsible for forwarding the multicast packets by applying Random Linear Network Coding (RLNC). RLNC has great potential to improve the performance of multicast routing protocol. The objective of this paper is to improve the performance of On-Demand Multicasting Routing
Protocol (ODMRP) with respect to reliability using RLNC over MCDS for WSN, so that bandwidth utilization can be increased in the network. The proposed approach is named as RLNMCDS-ODMRP, which deliver multicast data in high reliable. Experimental results and performance analysis show that the proposed protocol outperforms the classical multicast routing protocols that use MCDS or RLNC.
