Unmanned Aerial ad Hoc Networks: Simulation-Based Evaluation of Entity Mobility Models’ Impact on Routing Performance

An unmanned aerial ad hoc network (UAANET) is a special type of mobile ad hoc network (MANET). For these networks, researchers rely mostly on simulations to evaluate their proposed networking protocols. Hence, it is of great importance that the simulation environment of a UAANET replicates as much as possible the reality of UAVs. One major component of that environment is the movement pattern of the UAVs. This means that the mobility model used in simulations has to be thoroughly understood in terms of its impact on the performance of the network. In this paper, we investigate how mobility models affect the performance of UAANET in simulations in order to come up with conclusions/recommendations that provide a benchmark for future UAANET simulations. To that end, we first propose a few metrics to evaluate the mobility models. Then, we present five random entity mobility models that allow nodes to move almost freely and independently from one another and evaluate four carefully-chosen MANET/UAANET routing protocols: ad hoc on-demand distance vector (AODV), optimized link state routing (OLSR), reactive-geographic hybrid routing (RGR) and geographic routing protocol (GRP). In addition, flooding is also evaluated. The results show a wide variation of the protocol performance over different mobility models. These performance differences can be explained by the mobility model characteristics, and we discuss these effects. The results of our analysis show that: (i) the enhanced Gauss–Markov (EGM) mobility model is best suited for UAANET; (ii) OLSR, a table-driven proactive routing protocol, and GRP, a position-based geographic protocol, are the protocols most sensitive to the change of mobility models; (iii) RGR, a reactive-geographic hybrid routing protocol, is best suited for UAANET

Comprehensive experimental performance analysis of DSR, AODV and DSDV routing protocol for different metrics values with predefined constraints

A Mobile Adhoc Network is a multi-hop self-configuring network without any fixed infrastructure. Due to mobility of nodes, dynamic topology and highly dynamic environment, designing and implementing stable routing in Mobile Ad-hoc Networking is a major challenge and a critical issue. This paper analyses the performance analysis of on demand routing protocol, Dynamic Source Routing (DSR), Adhoc on Demand Distance Vector Routing (AODV) and table driven protocol, Destination-Sequenced Distance Vectoring (DSDV) using a network simulator NS2. Different types of test scenario have designed with fixed number of nodes but varying mobility. Different performance metric values like, throughput, delay, normalized network load, end to end delay, dropped packets, packets delivery ratio have been observed. The experimental results have been analysed and recommendation based on the obtained results has been proposed about the significance of each protocol in different scenarios and situations. The simulation results show that both protocols are good in performance in their own categories. We believe that findings of this paper will help the researcher to find the best protocol under predefined condition with varied mobility. We believe that this research will help the researcher to identify and further investigate any particular metrics value of AODV, DSR and DSDV

EVALUASI PERFORMANSI PROTOKOL RUTING DSDV DAN DSR PADA JARINGAN WIRELESS MOBILE AD HOC NETWORK (MANET)

ABSTRAKSI: Kebutuhan masyarakat global di era informasi saat ini sangat tinggi. Masyarakat menginginkan hal-hal yang serba mudah, praktis dan efisien namun tidak mengurangi kualitasnya. Mobile Ad Hoc Network (MANET) merupakan salah satu teknologi yang menawarkan kemudahan tersebut. MANET adalah sebuah teknologi dalam wireless LAN yang tidak memerlukan adanya sebuah infrastruktur dalam jaringannya. Mobile Ad Hoc Network (MANET) dibutuhkan pada tempat-tempat dimana tidak memungkinkan dibangun sebuah jaringan infrastruktur, seperti daerah bencana alam, daerah operasi militer ataupun konferensi yang membutuhkan kecepatan akses ke jaringan. Salah satu aspek penting dalam MANET adalah protokol rutingnya. Dimana protokol inilah yang mengatur sistem pencarian rute paket data dalam jaringan tersebut. MANET memiliki banyak protokol ruting untuk membangun topologi secara dinamis. Pemilihan protokol ruting MANET sangat dipengaruhi oleh kondisi jaringan tersebut. Dalam tugas akhir ini dilakukan perbandingan dua protokol ruting mobile ad hoc yang berbeda tipe, yaitu Destination Sequenced Distance Vector (DSDV) dengan tipe table driven dan Dynamic Source Routing (DSR) dengan tipe On Demand dengan simulasi menggunakan Network Simulator. Parameter-parameter yang diuji yaitu Packet Delivery Ratio, End to end delay, Routing Overhead dan Throughput. Hasil dari simulasi ini digunakan untuk menentukan penggunaan protokol mana yang lebih baik dalam suatu kondisi jaringan ad hoc seperti tingkat mobilitas dan ukuran/size dari jaringan tersebut. Hasil analisis menunjukkan protokol ruting DSDV memberikan harga delay yang lebih baik dibanding DSR dalam setiap kondisi jaringan. Namun untuk kondisi jaringan dimana terjadi perubahan jumlah node, harga routing overhead dan throughput DSR masih lebih baik dibandingkan DSDV, sedang untuk harga PDR cenderung sama baiknya untuk kedua protokol. Sedangkan untuk perubahan konektivitas dan tingkat mobilitas yang semakin tinggi DSDV lebih baik dibandingkan DSR.Kata Kunci : DSDV, DSR, PDR, End to end delay, Routing Overhead, Throughput.ABSTRACT: Demand of the people in this age of information is very high. People wanted everything to be simple, pratical and efficient with high quality. Mobile Ad Hoc Network (MANET) is one of them that offering the favor. MANET is one of wireless LAN technology which is no need an infrastructure in its network. Mobile Ad Hoc Network (MANET) was required at the places where there is no way to build an infrastructure network as disaster zone, military operation district or a conference which is requiring a faster access to the network. One of the important things in MANET is routing protocol. Routing protocol is the one that controlling routing system in the network. MANET has a lot of routing protocols to build a dynamic topology. Determination to choose routing protocol in MANET was based on the network condition. This final paper already evaluate the comparison between two ad hoc routing protocols which are Destination Sequenced Distance Vector (DSDV) and Dynamic Source Routing (DSR) with simulation using Network Simulator. Parameters which will be compared are Packet Delivery Ratio (PDR), End to End Delay, Routing Overhead and Throughput. The result of this simulation has been used to determine which one of the routing protocols will be better in one condition of the network like level of mobility and the size of the network. The result of analysis performs that DSDV routing protocol shows better delay than DSR in all of network condition. But in the “increasing number of node” network condition, routing overhead and throughput performance level of DSR is still better than DSDV, while PDR performance of both routing protocols are relative the same. For the “increasing number of connectivity” and “increasing level of mobility” network condition DSDV performs a better performance than DSR.Keyword: DSDV, DSR, PDR, End to end delay, Routing Overhead, Throughput
