In mobile ad hoc network communication is performed usually by using only send and receive messages and every node is powered by limited energy from low capacity battery. Every send or receive message takes particular amount of energy from the node. So node’s total energy level gradually decreases each time while it is sending or receiving something. In this way node will die out and packets coming from the source will be dropped since one of the routing node on the current route is no longer functioning. These packet loss events are observed and minimized in this paper. In the proposed approach, when source receives Warning Message from any routing node on the ongoing route then it will stop sending packets on the ongoing route. Critical energy level of routing node has been defined to generate a Warning Message when routing node’s energy level reduces to critical energy level.

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.

The Impact

Advances in wireless technology and mobile computing have provided a major impetus towards development of P2P network over MANET. Both peer-to-peer overlays and mobile ad-hoc network share the key characteristics of self-organizing and decentralization; both need to solve same fundamental problem, that is, how to route queries or packets efficiently. Congestion affecting the performance of P2P overlay on wireless ad-hoc network occurs not only due to buffer overflow but also due to error prone nature of the wireless medium used and the mobility of users. When paths of multiple downloading sessions intersect with each other, they mutually cause congestion for each other that result in packet drops. We identified that P2P MANET suffers query performance primarily due to significant congestion during download session. The unawareness of congestion in P2P MANET system may lead to the longer user response time, high overhead and many packet losses. In order to alleviate the congestion problem, we propose a modification to RAON, CANON, which includes congestion awareness for improving the RAON performance. We evaluated our system through simulation, which shows that CAON improves the performance of query success rate, query delay, packet losses significantly. We also evaluated the impact of mobility model on our system by simulating under both Random way point mobility model and Manhattan mobility model.

Transmission package delivery can be a problem of routes on the network, one of them is the Wireless network. Mobile Ad-Hoc Network (MANET) topology is often used on Wireless networks. The existence of a malicious node is a threat to MANET. Package delivery uses AODV and AOMDV Protocol Routing in TCP and UDP packet transmission. This study uses a simulation method using NS2, NAM and AWK. The Quality of Service (QoS) parameters used are throughput, packet loss, and jitter. Simulations are carried out using malicious nodes, the results on the AOMDV TCP graph have the highest input values and the best packets but are difficult to minimize energy, while for the TCP jitter values graph is best because it has a flow control function that can adjust the trajectory. The results in AOMDV TCP have the highest input value and the best packet loss but it is difficult to minimize energy, while for TCP value jitters it is best because it has a flow control function that can adjust the trajectory

Indonesia merupakan kawasan yang rawan bencana. Selain menimbulkan korban, bencana alam juga meruntuhkan banyak infrastuktur, salah satunya infrastruktur komunikasi. Dengan adanya masalah komunikasi dengan infrastuktur yang terbatas seperti yang terjadi di daerah bencana, solusi yang dapat dilakukan adalah dengan membangun Mobile Ad-hoc Network (MANET) karena memerlukan infrastruktur yang sederhana. Pada tugas akhir ini dilakukan pengujian dan analisis kualitas layanan (Quality of service) pada MANET menggunakan perangkat raspberry pi serta routing protokol Babel. QoS mengacu kepada kemampuan jaringan untuk menyediakan layanan yang baik melalui teknologi dan infrastruktur tertentu yang bertujuan untuk pertukaran informasi agar tersampaikan dengan baik. Parameter yang dijadikan acuan dalam penelitian ini antara lain adalah delay, jitter, throughtput dan  packet loss. Pengujian menggunakan topologi mesh dengan empat skenario, satu skenario dengan kondisi full connected dan tiga skenario dengan kondisi partial connected sekalian juga mengetahui mekanisme protokol yang digunakan, selain itu dilakukaan juga saat terjadi interferensi dan tidak terjadi interferensi. Secara keseluruhan, hasil kualitas layanan pada saat pengujian dengan skenario topologi kondisi full connected pada MANET yang dibangun, lebih baik dibandingkan dengan kondisi partial connected.

Indonesia merupakan negara kepulauan yang memiliki banyak wilayah yang sulit dijangkau, terutama di daerah perbatasan atau rural. Selain itu ketidaksetaraan distribusi penduduk dan ekonomi membuat pembangunan infrastruktur Teknologi Infomasi dan Komunikasi (TIK) secara keseluruhan di Indonesia tidak merata. Provider penyedia Telekomunikasi dan layanan internet di Indonesia belum dapat memenuhi kebutuhan infrastruktur di daerah terpencil. Solusi komunikasi yang berkembang cepat dan tanpa infrastruktur adalah MANET. MANET adalah sekumpulan node nirkabel yang bekerja sama membentuk jaringan. MANET terbentuk dari sekian banyak host yang terkoneksi melewati router tanpa inftrastruktur yang tetap dan berubah–ubah.  Pada pengujian dengan 5 node, kemudian dilakukan analisis QoS dengan standarisasi TIPHON, didapatkan nilai Sangat Bagus Ketika diuji dengan paket 1500 dan 2000 byte mendapatkan nilai indeks lebih dari 3 di Delay, sedangkan Jitter mendapkan nilai Sangat Bagus disemua pengujian dengan nilai indeks diatas 3.  Sedangkan Packet Loss mendapatkan nilai Sangat Bagus pada pengujian paket 1000 dengan nilai dibawah 3, pada pengujian throughput mendapatkan nilai TIPHON Sangat Jelek. Performa MANET dengan routing Babel layak digunakan model komunikasi alternatif karena masih mendapatkan nilai Sangat Bagus pada beberapa pengujian.

<p>The aim of this paper is to model the Portable Manager and allow it to aid in communication among Mobile Ad-hoc Networks (MANETs) carrying information across the mobile nodes in the network. In this article, Modeling Portable Manager aiding in the MANET Communication (MMAC) is proposed. The novelty is present in the use of node performance parameter called as α defined as the ratio of the packet received, packet loss and delay of the node which could be used for the next hop selection in the mobile ad hoc network. The Portable Manager (PM) is used to find out the relay node in the network. The working of the PM with a minimal number of nodes is analyzed and presented through the simulations in the network simulator.</p>
