In this paper, the authors basically divided in two parts out of which first part focuses on the existing topologies that are used in the wireless sensor networks and second part emphasis on the architecture of the node. As the people all know that wireless sensor network technology is the application oriented technology so topology and architecture of the network will always vary from application to application i.e. dynamic in nature. The development and deployment of the nodes always differ from traditional technologies; no doubt initially the traditional technology has been used but the excessive use of traditional technology changed the scenario.
