nowadays securing your network is very important and became really a great issue. hence, i think going with this area is very useful as you get new techniques to secure your internet. so please is there any latest topic regarding wireless network security?
There are various different types of security issues exist in WSN, the selection of topic is depend on your knowledge of area. Also read my article on security issues and challenges, black hole and sinkhole attack detection. The general areas of security in WSN are:
1. Cellular network security
2. Physical layer and data link security
3. Secure routing in WSN
4. Privacy issues in WSN
5. Adaptive Security for Multi-layer Ad-hoc Networks
Hope these topics will help you to go further.
I would advise to look at the proceedings of the good conferences in the field and see what other people are doing.
