Abstract: Wireless Sensor Network (WSN) comprises of large number of sensor nodes by random process. It has become one of the most interesting areas of the modern communication systems. It distributes its function in terms of three categories such as recongnization of nodes, perfroming the task and transmission and reception. As WSNs are mostly deployed in hostile areas, energy conservation and security aspect are vital design parameters for a routing protocol in WSNs. Cluster based protocols are proved to perform better compared to flat routing. Existing routing algorithms can be modified appropriately so that energy metric has to be considered for the route computation. Also some applications of WSNs like military and medical applications need the highest degree of authenticity assured. Thus many research problems can be developed in these areas. This paper focusses on to explore the research gaps in the fields of secure and energy aware data communication in wireless networks with respect to devise algroithm for routing computation, public key cryptography and network efficiency.
