With the development of household appliances, the short of communication among them is more and more becoming a problem. At present there is no central point of control among the traditional home appliances, and we cannot access them through Internet. To solve these issues, home network is proposed to connect all the appliances, home PC and portable devices together using network technology. Controlling all the appliances through one single node ( the home network gateway), home network makes life much simpler and convenient. There are several local area network technologies applicable to home network. Bluetooth technology is chosen in this paper as the home networking technology due to its many advantages over others. The implementation scheme of home control sub-network based on Bluetooth serial part profile ( SPP) and the standards of Home Network Platform in China is proposed. According to actual application fields, the communication protocol architecture for this scheme is established by using appliance control protocol promoted by the manufacturers and universal device control protocol ( UDCP) over SPP. Many management functions of appliance terminals are realized such as appending, login, operation, logout and alarming. Implementation methods of appliance terminal based on an entirely embedded single-chip manner and mobile control terminal which is realized by computer simulation are proposed. Analysis and solution of baud rate error brought by inaccurate crystal frequencies are presented. Further discussion about applying ad hoc technology to home control sub-network is carried out.

ABSTRAK Mobile Ad-hoc Network (MANET) sebagai wireless local area network yang bersifat dinamis dalam hal pergerakan node berperan untuk mengkondisikan setiap terminal client sebagai backwarding/fowarding-devices. Dengan demikian kondisi topologi jaringan akan berubah seiring dengan perubahan posisi pada node-client. Hal ini tentu saja akan memberikan keuntungan yang baik pada client dalam segi fleksibilitas tempat, mengurangi biaya instalasi, reduksi penyediaan infrastruktur dan sifat temporary instalasi sesuai dengan kebutuhan yang diinginkan. Pada penelitian ini telah dilakukan pemodelan dan simulasi untuk menunjukkan algoritma routing-network, status node yang terlibat dalam MANET, dan perhitungan nilai QoS dari komunikasi-data yang dibangun antar node yang saling bertetangga. Hasilnya menunjukkan perubahan topologi jaringan mengalami perubahan seiring dengan perubahan skenario yang dibangkitkan secara random dan stokastik; dan perubahan topologi jaringan ini merepresentasikan perubahan posisi node dalam MANET saat membangun komunikasi-data dari node-sender ke node-receiver. Metode pengujian menggunakan teknik kuantitatif serta kondisi random direpresentasikan dengan pembangkitan bilangan random yang bekerja berdasar Distribusi Normal/Gauss. Algoritma SNetS yang digunakan telah dapat mengakomodir jumlah N-node, sehingga kondisi node-terminal, bagaimana status node, serta QoS yang didapatkan mendekati kondisi real. Kata kunci: mobile ad-hoc network, backwarding/fowarding-devices, model, topologi dinamis, random, algoritma SNetS.

In the present study, an ultra-wideband (UWB) antenna has been proposed using coplanar waveguide (CPW) feed with dual-band-notch characteristics. Slot-loaded radiator and U-shaped CPW resonator are used for band rejection at 3.5 and 5–6 GHz respectively to reduce interference with existing World interoperability for microwave access and wireless local area network systems. With an extended operating band (measured at 10 dB return loss) the antenna operates successfully over the entire UWB range (3.1–10.6 GHz) with a form factor of 30 × 20 × 1.524 mm3 on a commercially low-cost FR-4 substrate. Experimental measurement results are presented in support of the simulated results for the proposed antenna for practical application. The antenna has been successfully fabricated and measured, showing broadband matched impedance and good omnidirectional radiation pattern throughout the operating bandwidth. Measured time-domain analysis for both the orientations, i.e. face-to-face and side-by-side, yields excellent performance in the open environment scenario. With fairly good and consistent monopole such as omnidirectional radiation patterns in H-plane and linear transmission responses, the proposed antenna is well suited to be integrated within portable devices.

The advent of wireless computing and massive processing power available within portable devices provides organizations with an unprecedented ability to provide flexible computing services on-demand to enable business initiatives and this development has increased the demand for wireless network security, which if unaddressed enables the theft of data, lowers productivity, and causes quantifiable financial losses. Flaws arising from wireless protocol with networking design and implementation errors present challenges to the Wireless Fidelity (Wi-Fi) community of users. In this paper, we attempt to document and classify the flaws in Wi-Fi Protected Setup (WPS), then proving the existence of this flaw with a WPS Pin Cracking Method, and presenting a Reverse Engineering countermeasure to eliminating WPS from an Access Point firmware, including other recommendations to helping the network administrators not repeat the errors that are the root causes of flaws of wireless networking in general from being exploited. By implementing the various techniques discussed in this paper, a better and more secure wireless network will be developed.
