This paper addresses the performance of geographical routing protocol in wireless networks, where only few nodes possess self- locating capability such as GPS. To be able to apply end-to-end geographical routing protocol...

To satisfy the user requirements for continuous and real-time multimedia information, the concept of Quality of Service (QoS) has emerged as a main issue in mobile ad-hoc networks. QoS routing is to find a route accordin...

A large variety of permutation routing protocols in a single-hop Network are known to day. Since they are single hop, there is always a wireless path connecting two nodes. One way to solve this problem in a multiple hop...

Label switching, which in IP networks is exemplified by MPLS and its extensions MPLambdaS and GMPLS, appears as one of the best alternatives to offer a reliable and flexible control plane for WDM networks, since it allow...

The scenarios of Ubiquitous Computing are becoming reality in the last years. The evolution in the technologies of wireless networks is making possible the existence of these ubiquitous scenarios. Mobile ad hoc networks...

We present ADMP, the adaptive mesh-based multicast routing protocol, in which nodes are able to independently tune the amount of redundancy used to transmit data packets with the goal of improving the overall packet deli...

A wireless ad hoc network is a collection of wireless nodes that can dynamically self-organize into an arbitrary and temporary topology to form a network without necessarily using any pre-existing infrastructure. These c...

A mobile ad hoc network (MANET) is a collection of wireless mobile nodes forming a temporary network without the aid of any fixed communication infrastructure. Due to limited resources, frequent network partitions and un...

Existing position-based routing algorithms, where packets are forwarded in the geographic direction of the destination, normally require that the forwarding node knows the positions of all neighbors in its transmission r...

We propose in this paper a protocol, called QITAR, which will secure the ad-hoc routing process while guaranteeing end-to-end QoS requirements in terms of delay or bandwidth constraints. Our approach provides an intrusio...

Optimal resource allocation is an important issue in computer network administration. One of these problems involves finding an optimal route to transport certain traffic from a source node to a destination node. For me...

En la creación de redes de interconexión para computadores paralelos, es crucial un diseño eficiente debido a su impacto sobre las prestaciones. Por lo tanto, se debería incluir un sistema de encaminamiento de alta v...

Recently, awareness has been raised about a number of “blind” attacks that can be performed against the Transmission Control Protocol (TCP) and similar protocols. The consequences of these attacks range from throughp...

El Problema de Ruteo de Vehículos con Capacidad limitada consiste en encontrar la mejor asignación de órdenes de transporte a una determinada flota de vehículos para cumplir con todas las órdenes de entrega, minimiz...

IEEE 802.11 based network analysis has been largely focused on throughput performance. There has been a growing concern to provide quality of service (QoS) to this protocol suite, the result of which has been the conside...

Desde la definición del modelo de servicio multicast en IP [1], el uso de estas facilidades ha ido adquiriendo cada vez mayor importancia en el ámbito de la Internet. El número de aplicaciones que demandan transmisió...

Decoupling the permanent identifi er of a node from the node's topology-dependent address is a promising approach toward completely scalable self-organizing networks. Existing solutions use a logical tree-like structure ...

This article presents a routing framework for mobile ad-hoc networks, which was called as FRAd-hoc. The main goal of the contribution was the design and implementation of a structure that could gather generic characteris...

Ad hoc wireless networks have become the architecture of choice for peer to peer communications in areas where the telecommunications infrastructure is inadequate or has failed. A major challenge is the reliable delivery...

This work presents a multiobjective algorithm for multicast traffic engineering. The proposed algorithm is a new version of MultiObjective Ant Colony System (MOACS), based on Ant Colony Optimization (ACO). The proposed M...
