ireless Sensor Network is one of the fast emerging technologies in today’s communication world. The most important area for the lifetime of a wireless sensor network is its communication infrastructure, mainly how media access is controlled, how topology is organized and how accurately communication is carried out. In this paper we have proposed multiple optimization features, which are mainly based on adoption strategy for the cluster head selection, adoption strategy for the cluster formation, accessing media technique and optimizing network overall performance also we have enhanced intra and inter cluster communication by mitigating interference. Our clustering strategy and cluster head selection not only improves the media access performance but also optimizes the network lifetime. Our earlier proposed MAC algorithm, “Pilot Signal assisted MAC for WSN” is used as a base for this research.
