My research work is starting so I need to select a research area for so I can work in that area but I am confused, so please help me and suggest some research areas in wireless sensor networks.
Recently, the topic of cognitive radio based wireless sensor networks have attracted big interest among academics. The goal of this research area is helping cognitive radio networks in the process of detecting the primary activity by providing information on the current spectrum utilization. Herein, two interesting papers on that topic:
"Cognitive Radio Based Wireless Sensor Networks" and "Cognitive Radio-based Wireless Sensor Networks: Conceptual design and open issues". You can find more information about the subject of cognitive radio networks on my blog: http://www.cognitive-radio-networks.blogspot.com.
