Modern telecommunication and computer networks, including the Internet, are being designed for fast transmission of large amounts of data, for which Congestion Control Algorithms (CCAs) are very important. Without proper CCAs, congestion collapse of such networks is a real possibility. Random tele-traffic is a heterogeneous mixture of streams of data packets that have different quality-of-servi...

In a telecommunication network, hundreds of millions of call detail records (CDRs) are generated daily. Applications such as tandem traffic analysis require the collection and mining of CDRs on a continuous basis. The data volumes and data flow rates pose serious scalability and performance challenges. This has motivated us to develop a scalable datawarehouse/OLAP framework, and based on this f...

Article History: Received 5, May, 2015 Received in revised form 12, May, 2015 Accepted 6, June, 2015 Published online 28, June, 2015 VoIP (Voice Over Internet Protocol) is an advanced technology that has a great potential to develop new telecommunication with much lower cost and better QoS. VoIP, a new technology has been increasingly popular in recent times due to its affordability and reduced...

Location and mobility patterns of individuals are important to environmental planning, societal resilience, public health, and a host of commercial applications. Mining telecommunication traffic and transactions data for such purposes is controversial, in particular raising issues of privacy. However, our hypothesis is that privacy-sensitive uses are possible and often beneficial enough to warr...

The exponential growth of reliable IP networks provides a suitable and cost-efficient replacement for the legacy TDM based voice networks. In this paper we propose a new framework for modeling Voice over IP (VoIP) traffic based on a nonhomogeneous Poisson process (NHPP). We show that the NHPP can provide an exact fit for the call arrival data, and can also be approximated to a normal model unde...

This paper presents a new framework for Voice over IP (VoIP) traffic modeling based on a nonhomogeneous Poisson process. The telecom industry is heading towards replacing the legacy TDM networks with an IP core network. The purpose of traffic engineering is to minimize call blocking probability and maximize resource utilization. A challenge of migrating to an IP core network is to develop an en...
