N.SRINIVASA RAO, K.SRINIVASA RAO, K.MAHALAKSHMI

This paper deals with radio labeling of planar graphs. We proved that a certain class of planar graphs defined using the complete planner graphs, and a class of planar bipartite graphs defined using the complete bipartite graphs are radio labeled properly subject to the certain conditions. We also provide radio labeling for friendship graph
