Simple flooding phd thesis in mobile ad hoc networks 2012 the most basic broadcasting technique where each node rebroadcasts any received check this out exactly once. Although flooding is ideal for its simplicity and high reachability it has a critical disadvantage in that it tends to generate excessive collision and consumes the medium by unneeded and redundant packets.

A number of broadcasting schemes have been proposed in MANETs to alleviate the drawbacks of phd thesis in mobile ad hoc networks 2012 while maintaining a reasonable level of reachability.

These schemes mainly fall into two categories: While the former employs a simple yet effective probabilistic principle to reduce redundant rebroadcasts the phd thesis in mobile ad hoc networks 2012 typically requires sophisticated control mechanisms to reduce excessive broadcast. The key danger with schemes that aim to reduce redundant broadcasts retransmissions is that they often do so at the expense of a reachability threshold which can be required in many applications.

Among the proposed stochastic schemes, is counter-based broadcasting. In this scheme redundant broadcasts are inhibited by criteria related to the number of duplicate packets received.

For this scheme to achieve optimal reachability, it requires fairly stable and known nodal phd thesis in mobile ad hoc networks 2012.

The dynamic counter-based broadcast for mobile ad hoc networks

Though the counter-based scheme was among the earliest suggestions to reduce the problems associated with broadcasting, there have been few attempts to analyse in depth the performance of such an approach in MANETs. Accordingly, the first part of this research, Chapter 3, sets a baseline study of the /main-ideas-and-themes-of-romeo-and-juliet.html scheme analysing it phd thesis in mobile ad hoc networks 2012 various network operating conditions.

The second part, Chapter 4, attempts to establish the claim that alleviating existing stochastic counter-based scheme by dynamically setting threshold values according to local neighbourhood density improves overall network efficiency. This is done through the implementation and analysis of the Dynamic Counter-Based DCB scheme, developed as part of this work. The study shows a clear benefit of the proposed scheme in terms of average collision rate, go here rebroadcasts and end-to-end delay, while maintaining reachability.

The third part of phd thesis in mobile ad hoc networks 2012 research, Chapter 5, evaluates phd thesis in mobile ad hoc networks 2012 counting and tests its phd thesis in mobile ad hoc networks 2012 in some approximately realistic scenarios. The schemes are studied under metropolitan settings, involving nodes moving in streets and lanes with speed phd thesis in mobile ad hoc networks 2012 direction constraints.

Two models are considered and implemented: Phd thesis in mobile ad hoc networks 2012 broadcasting is a vital operation in most MANET routing protocols, investigation of stochastic broadcast schemes for MANETs has tended to focus on the broadcast schemes, with little examination on the impact of those schemes in specific applications, such as route discovery in routing protocols. The fourth part of this research, Chapter 6, evaluates the performance of the Ad hoc On-demand Distance Vector AODV routing protocol with a route discovery mechanism based on dynamic-counting.

That said, other routing protocols would be expected to interact in a similar manner.

Investigating TCP performance in mobile ad hoc networks

Results establish that mobile noticeable advantage, in most considered metrics can be achieved using dynamic counting with AODV compared to simple counting or traditional flooding. In summary, this research analysis the Dynamic Counter-Based scheme under a range of network operating conditions and applications; and demonstrates a clear benefit of the scheme when click to its 2012 under a wide range of considered conditions.

PhD thesis, University of Glasgow. Mobile ad hoc networks MANETs have become increasingly important in view of their promise of ubiquitous connectivity beyond traditional fixed infrastructure networks. Such networks, consisting of potentially highly mobile nodes, have provided new challenges by introducing special consideration stemming from the unique characteristics of the wireless medium and the dynamic nature of the network topology.
