Correlated usage of mobile devices intensifies traffic burstness and poses threat of congestion to current cellular-based wireless infrastructures. Inspired by the idea of integrating a cellular-based infrastructure with ad-hoc relaying, we propose a new architecture for the next-generation wireless networks, termed PARCelS, which utilizes roaming mobile hosts to perform route relaying. PARCelS...

Due to the explosion of smart devices, data traffic over cellular networks has seen an exponential rise in recent years. This increase in mobile data traffic has caused an immediate need for offloading traffic from operators. Device-to-Device(D2D) communication is a promising solution to boost the capacity of cellular networks and alleviate the heavy burden on backhaul links. However, dir...

Modern society is built on good roads and efficient transportation systems. Road safety has become the primary development issue within road infrastructures. Safety and mobility can, however, be jeopardized by poor highway design and construction or by operating procedures which allow unsafe driving conditions e.g. construction work zones, incident management or response to emergencies caused b...

In the next millennium, traffic signal systems will need to address many issues, spanning a broad range of technical, social, and political boundaries. With the increase in urbanization and traffic congestion comes a greater demand to operate our roadway systems with maximum efficiency. As traffic volume continues to increase, roadway capacity will increase at a slower rate. New technology, suc...

Vehicular Ad hoc NETworks (VANETs) have emerged as a platform to support intelligent inter-vehicle communication and improve traffic safety and performance. The road-constrained, high mobility of vehicles, their unbounded power source, and the emergence of roadside wireless infrastructures make VANETs a challenging research topic. A key to the development of protocols for inter-vehicle communic...

The future will bring many different network technologies, different operating systems, and different communication devices. Each system has its specific advantages and disadvantages. Especially in the mobile and wireless environment, a large variety of communication systems exists (GSM, WLAN, DECT, IrDA etc.). Driven by the requirements of communication infrastructures for traffic scenarios (c...

Problems such as resource and service discovery models, load balancing and scheduling, brokering are eminent in grid systems due to bottlenecks such as bandwidth and network traffic in the underlying communication infrastructures and their associated costs in fabricating a scalable and cost effect grid services infrastructure. The primary goals of this paper is to apply grid based coalition for...

Supervisory Control and Data Acquisition (SCADA) systems that operate our critical infrastructures are subject to increased cyber attacks. Due to the use of request-response communication in polling, SCADA traffic exhibits stable and predictable communication patterns. This paper provides a timing-based anomaly detection system that uses the statistical attributes of the communication patterns....
