This book was released on 2014 with total page 81 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most promising network that has emerged from the technology world is the mobile ad-hoc network or MANET. It is a type of multi-hop network. Wireless by nature, MANETs do not have a specific network infrastructure. It is a collection of wireless mobile devices that communicate with each other without the help of any third party backbone like a base-station or a router. It can be hard to imagine how every node in this type of network communicate with one another without having a router. In MANETs, nodes change locations with time, configure themselves and get the information transmitted from source to destination without the help of any router or base station. Hence, for efficient data transmission, it is critical to understand the type of routing that is being used by these networks. Since they have no specific routers to handle these tasks, it can be a monumental task for the nodes to efficiently determine a path to forward and route their packets when they are at constant motion. This research makes a comprehensive performance analysis of the various mobile ad-hoc routing protocols. Over 160 simulation scenarios have been conducted and as many as 6 performance parameters are analyzed and compared in three different scales of network to make it a comprehensive analysis. Significant work is done in this area for more than a decade and researchers around the world have come up with a wide range of results. In this research, the results from previous work are taken into account for comparison and a wide analysis is made to carve out the most efficient routing algorithm under various mobility scenarios. All the major proactive and reactive routing protocols viz. Destination sequenced distance vector (DSDV), Optimized Link State Routing (OLSR), Dynamic Source Routing (DSR) and Ad-hoc On-demand Distance Vector (AODV) protocols are compared in three different phases - mobility, speed and network load. Simulation results show that dynamic source routing protocol (DSR) performs the best in small networks while ad-hoc on demand distance vector (AODV) routing protocol performs the best in medium and large networks. Although OLSR fails to cope with the level of AODV, it can be a superior protocol having demonstrated comparable performance to AODV and its proactive nature of routing packets.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a simulation and performance evaluation analysis of the various routing protocols that have been proposed for the Mobile Ad Hoc Network (MANET) environment using the Network Simulator-2 (NS-2) tool. Many routing protocols have been proposed by the academic communities for possible practical implementation of a MANET in military, governmental and commercial environments. Four (4) such routing protocols were chosen for analysis and evaluation: Ad Hoc On-demand Distance Vector routing (AODV), Dynamic Source Routing (DSR), Destination-Sequenced Distance Vector routing (DSDV) and Optimized Link State Routing (OLSR). NS-2 is developed and maintained by the University of Southern California's Information Sciences Institute (ISI). Leveraging on NS-2 s simulation capabilities, the key performance indicators of the routing protocols were analyzed such as data network throughput, routing overhead generation, data delivery delay as well as energy efficiency or optimization. The last metric is explored, especially due to its relevance to the mobile environment. Energy is a scare commodity in a mobile ad hoc environment. Any routing software that attempts to minimize energy usage will prolong the livelihood of the devices used in the battlefield. Three important mobility models are considered, namely, Random Waypoint, Manhattan Grid, and Reference Point Group Mobility. The application of these three models will enhance the realism of simulation to actual real life mobility in an urban or military setup scenario. The performance of the routing protocols in varied node density, mobility speed as well as loading conditions have been studied. The results of the simulation will provide invaluable insights to the performance of the selected routing protocols. This can serve as a deciding factor for the U.S. Department of Defense (DoD) in their selection of the most suitable routing protocols tailored to their specific needs.

Available in PDF, EPUB and Kindle. Book excerpt: Interest in the research and development of MANETs has experienced a dramatic growth owing to the advancement of new technologies such as GPS, Bluetooth, WLAN, Wi-Fi, DVB-H, RFID & UWB. A Mobile ad-hoc network is an accumulation of wireless nodes forming a provisional network without any pre-established communication infrastructure. To facilitate communication within such networks, a routing protocol is used to discover and establish routes between a pair of nodes, so that message can be delivered in a timely manner. However, mobility patterns have significant effect on the performance of routing protocols and hence on MANETs. The same routing protocol can perform differently in different mobility model. This book, therefore, attempts to provide a comprehensive study and analysis of proactive and reactive routing protocols' behavior over realistic environment model under QoS constraints. It also provides detail simulation setup and results and investigation of mobility models' impact on mobile ad hoc networks for varying number of traffic sources, number of nodes, speed, and data transmission rates. Finally the book concludes by recommending a set of problems for further research.

Available in PDF, EPUB and Kindle. Book excerpt: This research is aimed to evaluate the performance of two prominent on-demand Reactive routing protocols AODV & DSR in order to achieve optimal performance in Mobile Ad hoc Network. My research efforts are focused on simulation experiments to explore several parameters such as traffic patterns, node density and initial pattern of nodes that may affect the routing performance. After the extensive simulation study, I will try to suggest various possible combinations of MANET routing protocols for various MANET scenarios, in order to get optimal performance. The major contribution of this research work includes the characterization study of different routing protocols using a different routing mechanism to MANET based on the observations, Finally, The attempt is made to recommend how the performance of AODV can be improved by varying the mobility speed in the scenario where network load exceeds a level. The evaluation in this research is performed by means of simulation using Network simulator 2.33 from Berkeley.
Download or read book Performance Analysis of New Algorithms for Routing in Mobile Ad hoc Networks The Development and Performance Evaluation of Some New Routing Algorithms for Mobile Ad hoc Networks Based on the Concepts of Angle Direction and Node Density written by Mohamed S. Elazhari and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad hoc Networks (MANETs) are of great interest to researchers and have become very popular in the last few years. One of the great challenges is to provide a routing protocol that is capable of offering the shortest and most reliable path in a MANET in which users are moving continuously and have no base station to be used as a reference for their position. This thesis proposes some new routing protocols based on the angles (directions) of the adjacent mobile nodes and also the node density. In choosing the next node in forming a route, the neighbour node with the closest heading angle to that of the node of interest is selected, so the connection between the source and the destination consists of a series of nodes that are moving in approximately the same direction. The rationale behind this concept is to maintain the connection between the nodes as long as possible. This is in contrast to the well known hop count method, which does not consider the connection lifetime. We propose three enhancements and modifications of the Ad-hoc on demand distance vector (AODV) protocol that can find a suitable path between source and destination using combinations and prioritization of angle direction and hop count. Firstly, we consider that if there are multiple routing paths available, the path with the minimum hop count is selected and when the hop counts are the same the path with the best angle direction is selected. Secondly, if multiple routing paths are available the paths with the best angle direction are chosen but if the angles are the same (fall within the same specified segment), the path with minimum hop count is chosen. Thirdly, if there is more than one path available, we calculate the average of all the heading angles in every path and find the best one (lowest average) from the source to the destination. In MANETs, flooding is a popular message broadcasting technique so we also propose a new scheme for MANETS where the value of the rebroadcast packets for every host node is dynamically adjusted according to the number of its neighbouring nodes. A fixed probabilistic scheme algorithm that can dynamically adjust the rebroadcasting probability at a given node according to its ID is also proposed; Fixed probabilistic schemes are one of the solutions to reduce rebroadcasts and so alleviate the broadcast storm problem. Performance evaluation of the proposed schemes is conducted using the Global Mobile Information System (GloMoSim) network simulator and varying a number of important MANET parameters, including node speed, node density, number of nodes and number of packets, all using a Random Waypoint (RWP) mobility model. Finally, we measure and compare the performance of all the proposed approaches by evaluating them against the standard AODV routing protocol. The simulation results reveal that the proposed approaches give relatively comparable overall performance but which is better than AODV for almost all performance measures and scenarios examined.

Available in PDF, EPUB and Kindle. Book excerpt: The dissertation presents an in-depth study of mobile routing protocols, particularly mobile collection protocols through a literature study, a theoretical model, and thorough experimental studies both in simulation and testbeds. A mobile collection service provides data delivery from stationary source nodes to a mobile user (or a sink) over multihop networks. One of the main contributions of this dissertation research is the Whirlpool Adhoc Routing Protocol (WARP), which efficiently routes data to a mobile destination within a static network. The key insight in WARP's design is that, when a destination moves, data traffic can use the existing topology to efficiently probe, repair, and communicate changes with the few control packets. Using simulation, controlled testbeds, and real mobility experiments, we find that using the data plane, rather than control plane, is highly effective due to the incremental nature of mobility updates. WARP leverages the fact that converging flows at the destination makes it the region of highest traffic. The dissertation also provides a theoretical basis for WARPs behavior, defining an update area where the topology must adjust when a destination moves. As long as packets arrive at a destination before it moves outside of the update area, WARP can repair the topology with the data plane.

Available in PDF, EPUB and Kindle. Book excerpt: This book includes a synthesis of some of our previsions research works. It presents firstly a study of interactions between two routing protocols (AODV, DSR) and two transport protocol versions (TCP New Reno, Vegas). After this study, we conduct some simulations to analyze the behavior of these protocols with different node mobility and network load values. The performance results of each protocol are examined to identify our own scenarios in order to evaluate our proposed solution for better interactions between these protocols. This solution is called CL-TCP (Cross Layer TCP). It is an adaptation of the TCP congestion control mechanism with some parameters provided by the routing layer (mobility nodes and the size of routing length). After the evaluation of CL-TCP, the results showed that it significantly improves the interactions between TCP Vegas and AODV protocols.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this chapter, we analyzed ad hoc on demand distance vector (AODV), dynamic source routing (DSR), and destination-sequenced distance vector (DSDV) routing protocols using different parameters of QoS metrics such as packet delivery ratio (PDR), normalize routing overhead, throughput, and jitter. The aim of this chapter is to determine a difference between routing protocol performance when operating in a large-area MANET with high-speed mobile nodes. After the simulations, we use AWK to analyze the data and then Xgraph to plot the performance metric. After that we use one-way ANOVA tools to confirm the correctness of the result. We use NS-2 for the simulation work. The comparison analysis of these protocols will be carrying out and in the last, we conclude that which routing protocol is the best one for mobile ad hoc networks.
