We propose a dynamic vehicular routing algorithm with traffic prediction for improved routing performance. The primary idea of our algorithm is to use real-time as well as predictive traffic information provided by a central routing controller. In order to evaluate the performance, we develop a microtraffic simulator that provides road networks created from real maps, routing algorithms, and ve...

With conventional dynamic routing algorithms, many query messages are required in a distributed environment for efficient multicast routing of any traffic volume. We have developed a dynamic routing algorithm that uses a predetermined path search in which an appropriate multicast path is dynamically constructed by searching only a few nodes. This algorithm can construct an efficient multicast t...

WirelessHART is the most widely applied standard in wireless sensor networks nowadays. However, it does not provide any dynamic routing mechanism, which is important for the reliability and robustness of the wireless network applications. In this paper, a collection tree protocol based, dynamic routing mechanism was proposed for WirelessHART network. The dynamic routing mechanism was evaluated ...

In this paper we study the problem of scheduling a given sequence activities where each activity consumes resource with limited availability. Activity durations as well consumptions are assumed to be time-dependent. Because interaction time-dependent and consumptions, policies based on starting in early possible may fail due unnecessarily high exceeding availability resource. We propose dynamic...

We present a machine learning based approach to link availability prediction to be used in low power wireless sensor network routing. Accurately predicting availability of intermediate quality links will enable cost-efficient routing without sacrificing reliability and stability. Our predictor performs just slightly better than a simple predictor.

In this paper we present a framework within ns-3 developed to support an emerging class of wireless routing protocols, called dynamic backpressure routing protocols. Specifically, we provide the design and implementation particularities introduced by dynamic backpressure routing within the ns-3 simulator. In addition, we describe the implementation of a fine-grained tracing methodology used to ...

Firstly i t reviews hardwired routing a kind of switching to dynamic routing for telecommunication network starting with dynamic alternate routing (DAR) to ATM (Asynchronous Transfer Mode) routing. Secondly it presents routing in data network or packet switching. Thirdly it reviews routing for wireless multi hop network with specia...

A Wireless sensor network is an infrastructure comprised of sensing (measuring), computing, and communication elements that gives an administrator the ability to instrument, observe, and react to events and phenomena in a specified environment. The administrator typically is a civil, governmental, commercial, or industrial entity. The environment can be the physical world, a biological system, ...
