Performance Analysis of Distributed Cache Invalidation Method in Mobile Ad hoc Networks using AODV and AOMDV Routing Protocols

Mobile Ad hoc Networks (MANETs) is an active wireless network that can be formed without any existing permanent framework networks. Mobile Ad hoc Networks is an independent structure of mobile nodes communicated with wireless channels. Distributed cache invalidation method is performed among intermediate routing mobile nodes. In MANETs routing protocols are provided desirable route establishments of the mobile nodes. Ad hoc On-demand distance vector routing protocol (AODV) was well known single route protocol , Ad hoc On-demand Multipath Distance Vector routing protocol (AOMDV) is extends the AODV protocol with multipath. These results are carried out in network simulator version2 (NS2), the performance is analyzed and compared between AODV and AOMDV routing protocols

PERFORMANCE EVALUATION OF SINGLE-PATH AND MULTIPATH MANETS ROUTING PROTOCOLS FOR DENSE AND SPARSE TOPOLOGY

Mobile Ad Hoc Network (MANET) is a multi-hop wireless network in which fixed infrastructure is not used. A single-path routing protocol is mainly proposed as a single route from source node to destination node, while a multipath routing protocol uses multiple routes from the source to the destination node. This paper evaluates the performance of single-path routing protocols which are Cluster Based Routing Protocol (CBRP) and Ad hoc On-demand Distance Vector (AODV) along with a multipath routing protocol which is Ad hoc On-demand Multipath Distance Vector routing (AOMDV) in MANET environments with varying node densities (Dense and Sparse). Network Simulator (NS2) was used to evaluate the performance of these routing protocols. Our experimental simulation results show that: AOMDV protocol is better than AODV and CBRP in terms of Delay for both Dense and Sparse topologies with variant traffic sources, whereas AODV is better than CBRP and AOMDV in terms of Packet Delivery Ratio (PDR) with all traffic sources in Sparse topology

ANALISIS MULTIPATH ROUTING PADA JARINGAN MOBILE AD HOC MENGGUNAKAN AD HOC ON DEMAND MULTIPATH DISTANCE VECTOR (AOMDV)

ABSTRAKSI: Jaringan mobile ad hoc merupakan sekumpulan host mobile yang secara nirkabel membentuk jaringan temporer dimana semua node didalam jaringan tersebut terhubung antara satu dengan yang lainnya melalui link nirkabel tanpa menggunakan infrastruktur maupun administrasi tersentral. Jaringan semacam ini diprediksikan akan memiliki topologi yang dinamis, random, dan multihop yang terdiri dari link-link wireless dengan bandwidth yang relatif sangat terbatas. Protokol perutingan pada jaringan ad hocsebagian besar hanya menggunakan satu rute antara sepasang node untuk berkomunikasi sehingga berdampak pada throughput yang dicapai. Padahal, antara node satu dengan node lain tersebut ada sekian banyak path yang dapat digunakan. Multi-path routing telah diusulkan dan telah diimplementasikan pada jaringan packet switch dan circuit. Ad hoc On-demand Multipath Distance Vector (AOMDV) merupakan ekstensi dari protokol AODV yang mampu menemukan multiple path untuk menuju ke tujuan dan menggunakannya sebagai path cadangan maupun menggunakannya secara bersamaan dan simultan. Pada tugas akhir ini akan dibahas mengenai multipath routing pada Mobile Ad Hoc Network yang akan disimulasikan untuk beberapa skenario mengenai protokol ruting, mobilitas, jumlah node yang berbeda-beda.Kata Kunci : Wireless, Mobile Ad Hoc Network (MANET), Multi-path Routing, AODV, DSR, AOMDV, Simulasi, NS2.ABSTRACT: Mobile Ad hoc Network is a group of mobile host that can build temporary network wirelessly in which all node in the network connected each other through wireless link without any infrastructure or centralized administration. This kind of network has dynamic, random and multi hop topology that consist of wireless links with very limited bandwidth.Most of routing protocols used in ad hoc network only use one path as best path to communicate and sending packets each other so it influence to throughput and security itself, eventhough during route discovery process the protocols found more than one paths from source node to destination node.Multipath routing has been proposed and implemented in packet switch networks and circuit networks. Ad hoc On-demand Multipath Distance Vector (AOMDV) is an extension of Ad hoc On-demand Distance Vector (AODV) that has the ability to find multiple paths to reach destination node and use those paths as alternative route or use those simultaneously.In this final task will discuss and analyze about AODV-based multipath routing in mobile ad hoc network. An NS2 simulation will be used to reach this goal. The scenarios will be written to analyze the effect in using multipath routing protocol compare to AODV and DSR routing protocol, the effect of mobility to each routing protocols and the effect of number of nodes to each routing protocols.Keyword: Wireless, Mobile Ad Hoc Network (MANET), Multi-path Routing, AODV, DSR, AOMDV, Simulation, NS2

Receiver-based ad hoc on demand multipath routing protocol for mobile ad hoc networks

Decreasing the route rediscovery time process in reactive routing protocols is challenging in mobile ad hoc networks. Links between nodes are continuously established and broken because of the characteristics of the network. Finding multiple routes to increase the reliability is also important but requires a fast update, especially in high traffic load and high mobility where paths can be broken as well. The sender node keeps re-establishing path discovery to find new paths, which makes for long time delay. In this paper we propose an improved multipath routing protocol, called Receiver-based ad hoc on demand multipath routing protocol (RB-AOMDV), which takes advantage of the reliability of the state of the art ad hoc on demand multipath distance vector (AOMDV) protocol with less re-established discovery time. The receiver node assumes the role of discovering paths when finding data packets that have not been received after a period of time. Simulation results show the delay and delivery ratio performances are improved compared with AOMDV

An IOT-enabled System for Marine Data Acquisition and Cartography

Current satellite communication remains very expensive and impractical for most small to mid-sized vessels, and at the same time marine wireless networking is lack of network coverage. To solve this problem, this paper proposes a novel IOT (Internet of Things) enabled system for marine data acquisition and cartography based on Ship Ad-hoc Networks (SANET’s). Ships are equipped with Very High Frequency (VHF) radios and several sensors such as sea depth, temperature, wind speed and direction, etc. The collected sensory data is sent to 5G edge clouds incorporated at sink/base station nodes on shore, and ultimately aggregated at a central cloud on the internet to produce up to date cartography. The routing protocols deployed are DSDV (Destination-Sequenced Distance Vector), AODV (Ad hoc On-Demand Distance Vector), AOMDV (Ad hoc On-Demand Multipath Distance Vector) and DSR (Dynamic Source Routing) protocols, which are very popular in Mobile Ad-hoc Networks (MANET’s) and compatible with multi hop routing environments and scalability towards increased traffic and mobility. Simulation results verify the feasibility and efficiency of the proposed system that has packet delivery rates of up to 80% at shore base stations

Analysis of Routing Protocols over VANET

Vehicular Ad-hoc Network (VANET) is a new network technology where the cars are used as mobile nodes to form a communication network. In VANET, routing protocols have a significant role in terms of the performance because they determine the way of sending and receiving packets between mobile nodes. In this paper, we examine and analyze the performance of Ad-hoc On-Demand (AODV), Ad-hoc On-demand Multipath Distance Vector (AOMDV), Dynamic Source Routing (DSR) and Destination-Sequenced Distance Vector (DSDV) routing protocols over two different traffic connections; TCP and Constant Bit Rate (CBR) using different speeds and packet sizes. The performance measurements; Packet Delivery Ratio, Average End to End Delay and Average Throughput are examined with respect to speed and packet size. The objective of this study is to find the best routing protocol over all circumstances. Based on our validated results, DSR performs the best among all evaluated protocols

Composite Attribute Based Ad-hoc On Demand Multipath Distance Vector Routing Protocol (CAB-AOMDV)

281-284In this paper composite attribute-based ad-hoc on demand multipath distance vector (CAB-AOMDV) routing protocol has been proposed. Composite attributes are used to select the optimized multiple path for transmitting data and determined what percentage of total data can be share by the specific path. Composite factor is the combination of two factors, one is drop and another is queue factor. The performance analysis is evaluated under various node densities. Using control-overhead (CO), normalized-routing-overhead and throughput performance of proposed CAB-AOMDV is compared with Risk factor-based Ad-hoc on demand multipath (RF-AOMDV) routing protocol, from where it is observed that performance of proposed CAB-AOMDV is outperform RF-AOMDV in respect of all scenario taken into considerations

A Novel Mechanism for Multipath Routing in MANET
