Ad Hoc Networks are characterized by multi hop wireless connectivity, frequently changing network topology and the need for efficient dynamic routing protocols. In this project, we make a performance analysis of two of the protocols proposed for ad hoc networks using the extended ns-2 simulator Keywords— Ad Hoc Networks, Routing protocols, Global State Routing, Dynamic Source Routing

The dynamic changes of the topology caused by the movement of nodes makes routing become one of the key problems in the mobile Ad Hoc Networks (MANET). So how to optimize routing becomes a hot and difficult topic, among which optimizing routing cache is one of the key techniques. In this paper, we propose an adaptive dynamic cache routing (DCR) strategy based on DSR (Dynamic Source Routing), wh...

This paper focuses on two aspects of photonic network traffic performance investigation. Two different modelling approaches for the evaluation of network nodes under dynamic traffic conditions are described. This allows to evaluate how suitable different node architectures are for networks carrying dynamic traffic. Furthermore, routing strategies are becoming more important with increasing dyna...

One of the important research characteristic in the Mobile Ad hoc NETworks (MANETs) is routing. Development of efficient routing protocol is a necessity to improve the performance of routing. We propose an Efficient Interference Aware Multipath Dynamic Source Routing Protocol (EIAM-DSR) based on Dynamic Source Routing (DSR) protocol for MANETs. The main aim of the proposed routing protocol is t...

In today’s terminal operations, controller workload increases and throughput decreases when fixed standard terminal arrival routes (STARs) are impacted by storms. To circumvent this operational constraint, Krozel, Penny, Prete, and Mitchell (2004) proposed to use automation to dynamically adapt arrival and departure routing based on weather predictions. The present study examined this proposal ...

Major issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to re-routing instability problem. We study both the availability and the duration probability of a routing path that is subject to link...

High call volumes due to novel mobile data applications necessitate development of next generation wireless networks centered on high performing and highly available radio access networks (RANs). In this paper, we present an innovative IP-based wireless routing architecture (for a RAN) with mechanisms for seamless handoff operations and high Quality of Service (QOS). Algorithms for dynamic conf...

Wireless sensor network (WSN) is a developing technology, which has the promise of reforming the methods of collecting, processing and distributing information. The WSN becomes particular promising technology for the future. Due to technology development and availability of small, smart and economical sensors, WSN turns to productive, easily deployable, useful and powerful technology. It is nec...

DNS is a critical piece of the Internet supporting the majority of Internet applications. Because it is organized in a hierarchy, its correct operation is dependent on the availability of a small number of servers at the upper levels of the hierarchy. These backbone servers are vulnerable to routing attacks in which adversaries controlling part of the routing system try to hijack the server add...

This paper introduces to the publish/subscribe model the ability to uniformly access data produced in the past and future. The new model can filter, aggregate, correlate and project any combination of historic and future data. A flexible architecture is proposed consisting of distributed and replicated data repositories that can be provisioned in ways to tradeoff availability, storage overhead,...
