Perancangan, Realisasi, dan Analisa Sistem Keamanan Cloud Peer to Peer P2P Pada Jaringan IEEE 802.11

camera merupakan solusi terbaru sistem security dan tidak hanya terbatas ruangan, namun IP camera merupakan solusi jangka panjang yang sangat bermanfaat. IP camera sangat fleksibel. IP camera dengan fitur lainnya seperti pemilihan kamera dan fitur navigasi pada size video, kecepatan streaming. IP camera adalah CCTV (Closed Circuit Television) kamera yang menggunakan Internet Protocol untuk mengirimkan data gambar dan sinyal kendali atas Fast Ethernet Link. Dengan demikian IP camera juga sering disebut sebagai kamera jaringan. Yang mana IP camera ini biasanya juga memerlukan ADSL/DSL modem, cable modem, switch atau hub, agar bekerja dan berungsi dengan baik pada jaringan LAN atau Internet. Namun pada jaman yang semakin canggih ini, IP camera terus berkembang dengan selalu menciptakan teknologi terbaru, yakni salah satunya dengan didukung sistem cloud P2P. Peer to peer (P2P) digunakan untuk saling membagikan file data yang sudah tersimpan dalam suatu server. Pada sebuah smartphone dengan sebuah IP camera dihubungkan hingga koneksi terjalin antara IP camera dengan smartphone yang merupakan peer to peer networking. Sistem ini berguna untuk melihat-lihat gambar atau video dan mengendalikan dalam jarak jauh menggunakan smartphone. Hal ini juga mewakili arsitektur untuk meningkatkan pengawasan video menggunakan smartphone. Sistem ini memungkinkan komposisi dinamis aplikasi yang meningkatkan fleksibilitas keseluruhan sistem. Sistem surveillans video ini memenuhi semua kebutuhan dinamika yang memungkinkan penggunaan sistem kepada pengguna yang berbeda, sistem ini memberikan pengawasan yang lebih baik dengan memilih akses langsung untuk video dari lokasi yang berbeda.

Out of the classroom and into the workplace

According to the Wellcome Trust Monitor in 2013, most young people (63%) said they knew little or nothing about careers in science and very few (4%) knew a great deal. High quality continuing professional development (CPD) for teachers is one way to address these concerns, inspiring and informing teachers so that they may in turn do the same for their students. Since teachers will typically work with hundreds of young people over their career, the impact of effective CPD can potentially be huge. While CPD may often take place in school or through external conferences and workshops, other experiences are also key. The Royal Society's Vision report published in 2014 highlights the importance of teacher CPD being experienced through “peer-to-peer networking and sharing; technical visits to STEM-related sites; and mentoring provided at school and by business and industry”.

Parallel Evolutionary Peer-to-Peer Networking in Realistic Environments

In the present paper we first conduct simulations of the parallel evolutionary peer-to-peer (P2P) networking technique (referred to as P-EP2P) that we previously proposed using models of realistic environments to examine if P-EP2P is practical. Environments are here represented by what users have and want in the network, and P-EP2P adapts the P2P network topologies to the present environment in an evolutionary manner. The simulation results show that P-EP2P is hard to adapt the network topologies to some realistic environments. Then, based on the discussions of the results, we propose a strategy for better adaptability of P-EP2P to the realistic environments. The strategy first judges if evolutionary adaptation of the network topologies is likely to occur in the present environment, and if it judges so, it actually tries to achieve evolutionary adaptation of the network topologies. Otherwise, it brings random change to the network topologies. The simulation results indicate that P-EP2P with the proposed strategy can better adapt the network topologies to the realistic environments. The main contribution of the study is to present such a promising way to realize an evolvable network in which the evolution direction is given by users.
