In recent year wireless multimedia sensor network has developed so far that it has attracted various researchers focus toward itself. In wireless multimedia sensor network there are various interconnected devices such as low-cost CMOS cameras, microphone helps to retrieve the multimedia content such as video streams, audio streams and scalar sensor data from the environment so in this paper we have brings out various aspects of wireless sensor network, there protocols for wireless multimedia sensor network , challenges. And their future scope. And we also hope also that it will help new research to clear their ideas among its researchers.
