A few years ago, the applications of WSN were rather interesting example than a powerful technology. Nowadays, this technology attracts still more and more scientific audience. Theoretical works, where the WSN principles were investigated, grew into the interesting practical applications integrated by this time in a real life. Various application fields, from military to healthcare, are already covered by WSN. Hand in hand with WSN application coverage expansion, still new and new tasks bringing along the new interesting problems occur. Therefore such application practices stimulate the progress of WSN theory as well as unlock new application possibilities. Wireless sensor networks, as the spatially distributed networks consisted of relatively simple components interconnected mutually, provide quite wide application potential to be utilized in military, industry, transport, agriculture, healthcare and many other branches. However, in the near future, even higher growth of WSN application coverage could be expected. This expansion is nevertheless conditioned by solving questions related to the communication protocols standardization, to the lack of effective energy sources enabling network nodes working time prolongation, as well as to the progress in the field of ultra-low-power microelectronic components industry. An integration of WSN within the public data networks as well as within the domains where confidential and private data are proceed (e.g. E-Health) brings about problems related to the ethical and legal questions too. The WSN is one of actual affairs getting to the fore in the European Research Area since the issue of Future network technologies research and innovation is planned to be included in the new HORIZON2020 FP7 program. It is therefore necessary to create an experience-sharing platform for scientific researchers and experts from research institutes and WSN occupied companies that employ benefits of this modern technology and to the exchange of skills, experiences and new ideas from the WSN problematic within the all participants of iNetSApp.
