Unhindered security accomplishment in WSNs has always been threating task. Due to its compelling and tangled nature a lot of research work is going on all around the globe. Out of the various key topics Broadcasting from sink node to other sensor nodes has been the most sophisticated matter which is still untapped. A base station frequently broadcasts messages such as network query, time synchronization, multi-hop routing etc. The basic problem in such communication is source authentication because of untrusted receivers and unreliable communication environment. Therefore a unique topology is in demand. Keeping this theme in mind our proposed paper has come-up with such unique topology and an algorithm which can help sink node not only for broadcasting but also for multicasting and unicasting. Thus helps in improving security to a greater level.
