This paper presents an autonomic-based architecture for real-time traffic management in congested urban transportation networks. The architecture assumes the availability of a spatially distributed set of local controllers in the network. Each controller is capable of monitoring the traffic within a predefined subnetwork and provides efficient control strategies for its traffic. Following a pre...

We consider the following issues related to robust network routing in a highly dynamic and changing traffic environment: What network routing should an Internet Service Provider use so as to (i) accommodate users demanding “good” service while being unpredictable in the traffic that they would like to send to different destinations, (ii) minimize the amount of “overprovisioning” that needs to b...

Network Management is the process of managing, monitoring, and controlling the network. Conventional network management was based on wired network which is heavy and unsuitable for resource constrained WSNs. WSNs can have large scale network and it is impossible to manage each node individually. Also, polling mechanism of Simple Network Management Protocol (SNMP) impose heavy management traffic...

Administrators of today’s networks are highly interested in monitoring traffic for purposes of collecting statistics, detecting intrusions, and providing forensic evidence. Unfortunately, network size and complexity can make this a daunting task. Aside from the problems in analyzing network traffic for this information—an extremely difficult task itself—a more fundamental problem exists: how to...

Citizen wastes an important part of their life moving around a city, considering that most of these displacements are in vehicles, it could be said that good traffic conditions suppose a better quality of life and less environmental contamination. Thus, traffic management systems are one of the most important systems of a city. Nowadays, TICs are being incorporated so as to evolve to the Smart ...

Rule based traffic management is a methodology for dynamic traffic management that is a joint development of the different road authorities in the Netherlands. The approach tackles operational issues by disentangling problem detection, problem solution and conflict handling for each element in the road network. Each element in the road network follows the same generic rules and defers the traff...

The highly erratic and unpredictable behavior of wireless network traffic can be attributed to the combination of different factors: the variable number of users, the capacity of the access links/points, traffic matrices, users’ mobility, background traffic and the diversity of applications, services and user behaviors. These issues, together with the increasing demand for bandwidth and the eve...

With the expected growth of mobile data traffic it is essential to manage the network resources efficiently. In order to undertake this challenge, we propose a framework for network-centric, mobile-assisted resource management, which facilitates traffic offloading from mobile network to Wi-Fi or open access small cells. A provision of desired quality of experience to the end-user is carried out...

Network optimization concerned with operational traffic management in existing data networks is typically oriented towards either maximizing throughput in congested networks while providing for adequate transmission quality, or towards balancing the traffic so as to maintain possibly large free capacity for carrying additional (new) traffic. Nowadays, the reduction of power consumption is a new...

As mobile data traffic increases, and the number of services provided by the mobile network increases, service load flows as well, which requires changing in the principles, models, and strategies for media transmission streams serving to guarantee the given nature of giving a wide scope of services in Flexible and cost-effective. Right now, the fundamental question remains what number of netwo...
