BRICS: a building-block approach for analyzing routing protocols in ad hoc networks-a case study of reactive routing protocols

F. Bai, N. Sadagopan, A. Helmy
2004 2004 IEEE International Conference on Communications (IEEE Cat. No.04CH37577)  
One of the main challenges in ad hoc networks research is understanding the effect of mobility on the performance of routing protocols.  ...  In this study, we further extend our approach to analyze the interplay between mobility and the protocol mechanistic building blocks.  ...  We introduce a novel approach called BRICS to analyze the reactive ad hoc network protocols like DSR and AODV.  ...

We develop a detailed approach to study how mobility impacts the performance of reactive MANET routing protocols.  ...  However, our study suggests that at moderate and high velocities the exponential distribution with appropriate parameterizations is a good approximation of the path duration distribution for a range of  ...  In the flooding "building block", before flooding a route request in the network, DSR issues a route request with a TTL of 1 (nonpropagating route request).  ...

Modeling Path Duration Distributions in MANETs and Their Impact on Reactive Routing Protocols

F. Bai, N. Sadagopan, B. Krishnamachari, A. Helmy
2004 IEEE Journal on Selected Areas in Communications  
We develop a detailed approach to study how mobility impacts the performance of reactive MANET routing protocols.  ...  These two case studies illustrate how various aspects of protocol performance can be analyzed with respect to a number of significant parameters including the statistics of link and path durations.  ...  Consequently, Mobile Ad hoc NETworks (MANETs) are attracting a lot of attention from the research community.  ...

Performance analysis of wireless ad hoc networks [article]

Martin Drozda, University, My, University, My
2019
Acknowledgments I would like to give my thanks to Helena Szczerbicka for hosting me at the Simulation and Modeling Group at Universität Hannover where I am submitting this thesis.  ...  Routing protocols for ad-hoc wireless networks can be divided into proactive and reactive. The latter are also known as on-demand.  ...  Previously, understanding of ad hoc networks was based more on one's feel for a given setup rather than on a formal approach.  ...
