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.

Delay Tolerant

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.

In this time of instant units, Mobile Ad-hoc Network(MANET) has become an indivisible part for transmission for mobile devices. Therefore, curiosity about study of Mobile Ad-hoc Network has been growing because last several years. In this report we have mentioned some simple routing protocols in MANET like Destination Sequenced Distance Vector, Active Source Redirecting, Temporally-Ordered Redirecting Algorithm and Ad-hoc On Need Distance Vector. Protection is just a serious problem in MANETs because they are infrastructure-less and autonomous. Principal target of writing this report is to handle some simple problems and security considerations in MANET, operation of wormhole strike and acquiring the well-known routing protocol Ad-hoc On Need Distance Vector. This short article will be a great help for the people performing study on real world problems in MANET security.

Mobile Ad Hoc

A wireless ad hoc network is a decentralized kind of wireless network. It is a kind of temporary Computer-to-Computer connection. It is a spontaneous network which includes mobile ad-hoc network (MANET), vehicular ad-hoc network (VANET) and Flying ad-hoc network (FANET). Mobile Ad Hoc Network (MANET) is a temporary network that can be dynamically formed to exchange information by wireless nodes or routers which may be mobile. A VANET is a sub form of MANET. It is an technology that uses vehicles as nodes in a network to make a mobile network. FANET is an ad-hoc network of flying nodes. They can fly independently or can be operated distantly. In this research paper Fuzzy based control approaches in wireless network detects & avoids congestion by developing the ad-hoc fuzzy rules as well as membership functions.In this concept, two parameters have been used as: a) Channel load b) The size of queue within intermediate nodes. These parameters constitute the input to Fuzzy logic controller. The output of Fuzzy logic control (sending rate) derives from the conjunction with Fuzzy Rules Base. The parameter used input channel load, queue length which are produce the sending rate output in fuzzy logic. This fuzzy value has been used to compare the MANET, FANET and VANET in terms of the parameters Throughput, packet loss ratio, end to end delay. The simulation results reveal that usage of Qual Net 6.1 simulator has reduced packet-loss in MANET with comparing of VANET and FANET.
