How can i add code for a service called "Area Multicast send" in my program along with mentioned parameters

Multicasting: a set of data sent by one computer across a computer network to many users at the same time.

in this below program how can i add code for " AreaMulticastSend (position, radius, deadline, packet)"

Area multicast send is a service that identifies a destination area by its center position and radius. It guarantees that every node inside that area will receive a copy of the sent packet within the specified end-to-end deadline. so how can i do this , the output (figure) is also given below plz help me in adding this service to my below program. there are total 10 nodes(sensors) shown in figure so how can i multicast a packet from one node to others, (in short how can i implement speed real time protocol in matlab).

Note: if some cann't implement this service along with its parameters so just do it without parameters, means a bit of work/improvement in it would also be appreciated.

plz be confident to contact me for further questions about this program. thanks
