This dissertation was written as a part of the MSc in ICT Systems at the Intern a- tional He l lenic University. It is generally accepted that the wireless commun ication has become very popul ar and its everyday u se has increased. Many d evices have been developed that provide users a large number of servi ces, aiming to make their lives easier. Their incre ase rate has a d i- rect result at their domination on the market replacing the wired communic ation. We live in the era of “smart”. S mart phones, smart televisions, smart cars, and of course smart homes, i.e. , they can take decisions and acting alone without the need of human pre s ence. The home networking market is growing rapidly and wireless tech nologies pl ay an i m- portant role in the smart home networks. Using service - oriented approach es , we dete r- mine one of the main challenges of the home networking, the spectrum management. Several wireless technologies of varying bandwidth, ope r ating range, and form factor currently exist or are emerging for the home network ing (e.g. Wi - Fi, Bluetooth , ZigBee , WiMAX etc.) and thus may interfere with each other, if some str ategy for the manag e- ment of the spectrum i s not provided. Recent analysis shows that this s pectrum is not being utilized efficiently. So, this thesis will involve a literature search of the topic and then the proposal of a strategy for spe c- trum management . The main scope of this dissertation is to search and create a strategy on how to avoid dif ferent wireless systems sharing the same frequency band and opera t- ing in the same environment, to interfere with each other and experience a severe d e- crease in throughput. In the conclusion, we analyze the future of smart home as well as the possible spect rum management strategies should be followed .
