MANET's are usually characterized by random mobility of nodes, nodes arbitrarily entering and leaving the network and variable transmission range of nodes. These characteristics make MANET links to be intermittent and the topology to be highly dynamic. In such situations routing protocols are desired to be on-demand and robust enough to cope up with the dynamic topology changes. Many on demand routing protocols have been suggested for this purpose like single path Dynamic source routing (DSR) and Ad-hoc on demand distance vector routing (AODV) and their multiple path variants like Ad-hoc on demand multiple distance vector routing. These protocols suggest different ways to avoid route-looping problems and create shortest path route. Locally adaptive and multi-metric Ad-hoc on demand distance vector routing (LAM-AOMDV) tries to use multiple metrics to discover routes and proposes new schemes to provide route maintenance. The objective of a routing protocol is to efficiently find routes and transfer as many data-packets possible with minimum routing overhead. In our thesis work propose two layers of improvement one to reduce the overhead caused unnecessary transmission of hello packets and second to pre-emptively discover routes in cases of a link breakage, which renders a path useless. In our schemes we try to stop the unnecessary hello transmissions by nodes, which are not participating in an active route or in route discovery. We also try to improve the packet delivery ratio by finding routes pre-emptively before the last route becomes unavailable to the source. We compare the individual layers of improvement with LAM-AOMDV using various metrics like packet delivery ratio, overhead caused due to hello messages and packets dropped due to no route availability at the routing layer.

Available in PDF, EPUB and Kindle. Book excerpt: A self-contained text on modeling and performance evaluation of communication networks This quantitative book focuses on the real issues behind modeling and analysis of communication networks. The author covers a wide variety of topical networking subject matter based on the provided background material in probability, Markov chains, and queues. Leveraging this material, the author explores topics in local multiplexing and routing over three successive chapters, stressing both continuous-time and discrete-time contexts. The remaining chapters focus more directly on networking, such as traffic shaping and multiplexing, static routing, dynamic routing, and peer-to-peer file sharing systems. Providing more rigorous and technically deep coverage than most commonly used networking textbooks, An Introduction to Communication Network Analysis covers classical (e.g., queuing theory) and modern (e.g., pricing) aspects of networking in a clear, accessible manner. Chapters include: * Review of Elementary Probability Theory * Markov Chains * Introduction to Queuing Theory * Local Multiplexing * Queuing Networks with Static Routing * Dynamic Routing with Incentives * Peer-to-Peer File Sharing with Incentives Appendices include additional background information, solutions, and references for selected problems, making this an invaluable text for graduate-level students and networking researchers alike.

This book was released on 2018-07-27 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ad-hoc On-demand Multipath Distance Vector (AOMDV) routing protocol is widely used in highly dynamic ad-hoc networks because of its generic features. The transmission of reliable energy efficient data is an emerging issue in AOMDV routing as the nodes are prone to link failures and route breaks in highly dynamic ad-hoc networks. In order to eliminate such problems, a novel node disjoint multipath routing protocol called Link Reliable Energy Efficient AOMDV (LR-EE-AOMDV), the extension of a well-known AOMDV, is proposed here to find multiple link reliable energy efficient paths between any source and destination pair for data transmission using metrics such as Path Length, Path-Link Quality Estimator (P-LQE) and a novel Path-Node Energy Estimator (P-NEE).

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to unpredictable network topology changes, routing in Mobile Ad Hoc Networks (MANET) is an important and challenging research area. The routing protocol should detect and maintain a good route(s) between source and destination nodes in these dynamic networks. Many routing protocols have been proposed for mobile ad hoc networks, and none can be considered as the best under all conditions. This thesis presents the design and implementation of a new proactive multipath MANET routing protocol. The protocol, named Multipath Destination Sequenced Distance Vector (MDSDV), is based on the well known single path Destination Sequenced Distance Vector (DSDV). We show that the protocol finds node-disjoint paths, i.e., paths which do not have any nodes in common, except for the source and the destination. The thesis presents a systematic evaluation of MDSDV in comparison with three well known protocols: one proactive (DSDV), and two reactive (AODV) and (DSR). MDSDV behaves very well in terms of its packet delivery fraction and data dropped in both static and dynamic networks. It delivers nearly 100% of data in dense networks (networks with more than 20 nodes). The speed of the nodes and the number of sources have a low impact on its performance.

This book was released on 2009 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad hoc Networks (MANETs) are a key part of the ongoing evolution of wireless communications. MANETs are a collection of wireless mobile nodes that dynamically form a temporary wireless network without an infrastructure. The design of an efficient and reliable routing scheme and Quality of Service (QoS) support for MANETs is a major challenge. Unlike traditional routing schemes that seek only single path, multipath routing allows the establishment of multiple paths for routing between a source-destination pair. Multipath routing exploits the resource redundancy and diversity in the underlying network to provide benefits such as fault tolerance, load balancing, capacity aggregation and the improvement in QoS metrics such as delay. In the first part of the thesis, a multipath routing scheme, referred to as Shortest Multipath Source (SMS) routing based on Dynamic Source Routing (DSR) protocol is proposed. The mechanism has two novel aspects compared to other on-demand multipath routing schemes: it achieves shorter multiple partial-disjoint paths and allows more rapid recovery from route breaks. This scheme addresses the problem of wireless broadcast storms by simple hop count mechanism. The performance differentials are investigated using Network Simulator version 2 (NS-2). Results show the superiority of SMS under certain scenarios in terms of goodput of up to 85% and end-to-end delay of up to 99% when compared to the competing schemes. Although SMS is designed to find multiple shorter routes, these routes have no information about the network traffic or application requirements. The second aspect of the thesis addresses QoS support. Two novel capacity-constrained routing schemes based on SMS, which allow nodes to depend on their estimation of the residual capacity to make correct admission control decisions, are presented. The performance evaluation demonstrates the merits of the proposed schemes with a 20% increase in goodput while end-to-end delay is reduced by 47% and the necessity of QoS-aware multipath routing schemes in Mobile Ad hoc Networks becomes more apparent.

Available in PDF, EPUB and Kindle. Book excerpt: Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes that move freely and self-configure without a preexisting communication infrastructure. In MANETs, under the arbitrary movement of nodes and highly dynamic topology conditions, the routing protocols for fixed networks do not perform well. To adapt to the rapid change of topology, many routing protocols have been proposed. However, most of them chose the minimum hop-count routes. This choice can lead to significant reduction of the network performance because communication quality via the chosen links is not good. Thus, the evaluation of link quality is indispensable and interference is a key factor to be considered. In the literature, most of the existing interference-aware protocols are single path and the consideration for interference range is limited. Several proposed interference-aware multi-path protocols for MANETs are either not highly efficient or have the computational complexity of NP-hard.To tackle the above problems, we first determine an interference region of each link including all nodes that can interfere with this link. Then, we propose a formula to evaluate the interference level of each link. Based on the formula of the link interference, we develop a series of interference-aware multi-path routing protocols for mobile ad hoc networks. These interference-aware multi-path routing protocols minimize the impact of interference on the paths from the source to the destination to increase the network performance. The computational complexity of the protocols is polynomial and each of them is most suitable for a type of network size. To demonstrate the efficiency of the interference-aware multi-path routing protocols, we compare them to prominent protocols in different network sizes and a high mobility environment when the RTS/CTS (Request-To-Send/Clear-To-Send) mechanism is alternatively turned on and turned off. The simulation results show that our protocols significantly improve packet delivery fraction, and reduce end-to-end delay, routing overhead, and normalized routing load.The RTS/CTS mechanism is to restrict the collision caused by the hidden terminals. However, we indicate that the RTS/CTS mechanism is not suitable for mobile ad hoc network based on the simulation results.
