It is slightly curious that someone who is considering a final semester project of a BSc degree course (Hons no less!) (and therefore having supposedly been immersed in a high level academic environment for 2 or 3 years) should be asking for suggestions on the "Internet & Networking" section of a computer help forum, where the usual type of question is more like "Help! My router stopped working" or "What type of Cat5 cable should I buy?".
You need to refine your strategy. Have your studies not taught you anything about gathering and evaluating information in a focused way, reflecting on what you have already learned, consulting teachers and likely sources of relevant information?
For example, a quick Google search using this search term
final semester bsc hons degree project networking led me to what the University of Plymouth (UK) says about their BSC (Hons) course in Computer Networks:
You will ... have a final-year project where you will utilise the practical and theoretical skills that you have gained to build or develop an artefact related to networking. This can be anything that you have an interest in, an industrial project or a project supporting the research at the University.
And the University Of East London:
Students complete a project in their final year. This is a major piece of work that allows students to choose the direction of their study, to develop their own ideas and to integrate the various subjects studied. Students are encouraged to provide their own areas for this project, but there is always a battery of topics from which students can choose.
No doubt your own course literature includes such matter.
Do you see where they talk about "anything you have an interest in", "the skills you have gained", "their own ideas" and "the subjects studied"? This is telling you that the final project builds upon what you have already studied, using the skills you have (presumably) acquired. You have done the studying, not us, and you have acquired the skills, not us.
