Mobile Ad-Hoc Networks
Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of-the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: quality-of-service and video communication, routing protocol and cross-layer design. A few interesting problems about security and delay-tolerant networks are also discussed. This book is targeted to provide network engineers and researchers with design guidelines for large scale wireless ad hoc networks
Estudio del rendimiento de arquitecturas basadas en grupos para WAHSN
[ES] Existen muchos trabajos relacionados con las redes ad hoc y las redes de sensores donde se presentan nuevos
protocolos que encaminamiento que aportan mejores características, otros trabajos donde se comparan para
ver cual posee un mejor rendimiento ó incluso presentan nuevas aplicaciones basadas en este tipo de redes,
pero este trabajo aporta otro punto de vista. ¿Por que no ver la red como un conjunto que se divide en grupos
para aportar un mejor rendimiento a la red independientemente del protocolo de encaminamiento utilizado?.
Para ello, en este trabajo, vamos a demostrar a través de simulaciones, que la agrupación de nodos en redes
WAHSN (Wireless Ad Hoc & Sensor Networks) aporta mejoras a la red en general, disminuyendo el tráfico
de encaminamiento, el retardo, el throughput, etc. Este estudio se ha realizado evaluando los protocolos
estándar más utilizados (DSR [1], AODV [2] y OLSR [3]), así podemos observar cual de ellos aporta un
mejor rendimiento. Finalmente, se propone una arquitectura de red basada en grupos optimizada para las
redes WAHSN[EN] There are many works related with ad hoc networks and sensor networks where the authors present new
routing protocols with better or enhanced features, others just compare the performance of them or present
an application environment, but this work tries to give another point of view. Why don¿t we see the network
as a whole and split it intro groups to give better performance to the network regardless of the used routing
protocol?. First, we will demonstrate, through simulations, that grouping nodes in WAHSN (Wireless Ad
Hoc & Sensor Networks) improves the whole network by diminishing the routing traffic, the delay, the
throughput, etc. This study was conducted to assess the most used standard protocols (DSR [1], AODV [2]
and OLSR [3]) that gives better performance to the whole network when there are groups of nodes. Finally, a
group-based network architecture optimized for WAHSN is proposedGarcía Pineda, M. (2008). Estudio del rendimiento de arquitecturas basadas en grupos para WAHSN. http://hdl.handle.net/10251/13472Archivo delegad
