Available in PDF, EPUB and Kindle. Book excerpt: Mobile Ad-hoc network (MANET) is a collection of mobile nodes, which form a wireless network without the use of an existing infrastructure. 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. The objective of a routing protocol is to efficiently find routes and transfer as many data-packets possible with minimum routing overhead. 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 (AOMDV). These protocols suggest different ways to avoid route-looping problems and create shortest path route. Locally adaptive Ad-hoc on demand distance vector routing (PROPOSED-AOMDV) tries to discover more robust routes and proposes new schemes to provide route maintenance. In our thesis work we propose to compare the different techniques of path maintenance, mainly link layer detection and hello based connectivity. The goal is to analyze the behavior of different single path and multipath schemes for these mechanisms. With the increasing need to be able to send video traffic over mobile ad-hoc networks, it becomes critical to be able to send packets within a time constraint. Hence we have chosen to bring in a factor called 'time to live' or TTL. The scheme culminates with the introduction of a queue between the network and the MAC layer, i.e., the Interface Queue Layer in order to sort packets based on their priority. This scheme ensures that higher importance packets are always sent ahead of lower priority packets.

Available in PDF, EPUB and Kindle. Book excerpt: Satellite Network Robust QoS-aware Routing presents a novel routing strategy for satellite networks. This strategy is useful for the design of multi-layered satellite networks as it can greatly reduce the number of time slots in one system cycle. The traffic prediction and engineering approaches make the system robust so that the traffic spikes can be handled effectively. The multi-QoS optimization routing algorithm can satisfy various potential user requirements. Clear and sufficient illustrations are also presented in the book. As the chapters cover the above topics independently, readers from different research backgrounds in constellation design, multi-QoS routing, and traffic engineering can benefit from the book. Fei Long is a senior engineer at Beijing R&D Center of 54th Research Institute of China Electronics Technology Group Corporation.

Download or read book Flow Aware Admission Control Protocol for QoS Provisioning in MANETs written by Muhammad Asif and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In Mobile Ad hoc Networks (MANETs), mobile nodes communicate over an error prone wireless channel without any centralized control. MANETs have n9 fixed topology because mobile nodes can freely join or leave the network at any time. As a consequence, it is difficult to guarantee Quality of Service (QoS) in these networks. The current routing , protocols provide only best effort services to the applications. Multimedia communications become very popular and require various types of QoS guarantee from the network such as guranteed throughput, bounded end-to-end delay. The QoS-aware routing (QA) and Admission Control (AC) protocols try to address the issue of QoS to some extent. In this work, a novel Flow Aware Admission Control (FAAC) protocol is designed to assure the guaranteed throughput to data sessions. It utilizes the route cache of routing protocol and devises a new admission technique to accept or reject data session to the network. It is partially coupled with the Oynamic Source Routing (OSR) protocol as it has used the basic functionality of route search of the OSR protocol. The protocol has two phases: (i) route discovery and (ii) test the route nodes resources for a data session entry. The performance evaluations show that the protocol outperforms the existing best effort routing and QAR and AC protocols such as OSR and Contention Aware Admission Control (CACP) protocols in providing QoS in MANETs. Mobility is a big challenge to assure guaranteed throughput to data sessions. To address this issue, we have designed F AAC-Multipath protocol that uses multiple routes for data transmission. The protocol maintains two tested routes for each data session and devises new fast switching mechanisms that switch the data flow from one route to another to guarantee the throughput. Multimedia applications require guaranteed throughput as well as bounded end-to-end delay. To address this issue we.have designed Flow Aware Admission Control-Multipath with Multiple constraints (F AAC-MM). This protocol assures the application with guaranteed throughput as well as bounded end-to-end delay. FAAC-MM switches the data flow from primary to secondary route on the basis of achieved throughput and end-to-end delay. We have also analyzed and compared the proposed protocols with the state of the art protocols such as CACP and Multi-path for Mobile Ad Hoc Networks. The simulation results show that our protocol outperforms the above mentioned protocols.

Download or read book Load Distribution and Energy Awareness in Manets Using Multipath Routing written by Christos Tachtatzis and published by . This book was released on 2008 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless ad-hoc networks are characterised by lack of infrastructure and frequent topological changes. Traditional routing protocols seek only single paths to the desired destinations, while multipath routing obtains multiple paths for only marginal additional overhead. This work argues that multipath routing is advantageous, even allowing for the additional overheads, because of the improved network load distribution. The merits of multipath routing are shown through extensive performance evaluation considering packet delivery ratio, average end-to-end delay and routing efficiency, for both mobile and static scenarios. The second aspect of the thesis addresses energy awareness. When a single connection is considered, multipath routing can potentially consume more total energy compared to its unipath counterparts because some traffic can traverse longer (in terms of hop count) paths. On the other hand, unipath routing concentrates nodal traffic over the same single path; resulting in unfairness for the intermediate hops and uneven energy consumption which, in turn, can result in network partitioning. Here, it is argued that multipath routing extends the network lifetime, because the routing protocol can make more sophisticated decisions to avoid node exhaustion. Two novel energy aware routing schemes, which select optimal paths to homogenise the energy map of the network, are presented. A range of performance evaluation techniques are employed to demonstrate the merits of the proposed schemes, and it is shown that the approach of homogenising the network energy map mitigates against the effects of inevitable node outages cause by energy exhaustion and prolongs network lifetime.
