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 recent years, Vehicular Ad Hoc Network (VANET) has attracted considerable attention both from academia and industry. In VANET, multiple access technologies such as cellular system, Wireless Local Area Network (WLAN) are integrated to support the service requirements of vehicular users. Multi-hopping vehicular networks (VANETs) provide environmental awareness across large regions even if there does not exist direct communication between several vehicles within the region. However, the volume of messages that are received and rebroadcasted via the relay vehicles can cause broadcast storms and network jams. In them the systems are subject to wireless interference and disconnections, thus hindering the availability and reliability of source-destination connections. Another major problem arises when VANETs are sparse, causing excessive retransmissions and delays due to long periods without maintain connection between pair of vehicles. This article reviews the literature related to Vehicular Delay Tolerant Network with focus on Cooperation. It starts by examining definitions of some of the fields of research in VDTN. An overview of VDTN with cooperative networks is presented.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.

Microstrip antenna which designed with dual feeding at 2.4 GHz and 5.8 GHz can meet WLAN (Wireless Local Area Network) application.Antenna fabrication use PCB FR4 double layer with thickness 1.6 mm and dielectric constant value 4.4. The length of patch antenna according to calculation 28.63 mm, but to get needed parameter length of patch should be optimized to 53 mm. After examination, this antenna has VSWR 1.212 at 2.42 GHz and 1.502 at 5.8 GHz, RL -13.94 dB at 2.42 GHz and -20.357 dB at 5.8 GHz, gain of antenna 6.16 dB at 2.42 GHz and 6.91 dB at 5.8 GHz, the radiation pattern is bidirectional. Keywords : microstrip antenna, wireless LAN, dual polarization, single feeding technique
