As part of a complete wireless networking education, students must have an in-depth understanding of basic concepts such as signal propagation, environmental effects on RF signals, FCC regulations and limits, power levels, antenna construction and antenna operation. Lecture based curricula can only go so far in preparing a wireless professional to succeed(More)
Wireless networking, and especially wireless security, has become an increasingly important area of study for our students. To this end, we have developed a third course in our wireless sequence called Security of Wireless Networks. We have provided the students with a fast paced and interesting lab environment in which they can deploy the various(More)
In this article, we propose a model that can be used to study the costs and benefits of integrating cellular and wireless LANs, from a vendor and a user perspective. We explain the model and the approach to calculate the costs for a simple handoff topology that supports a voice call across a cellular and a WLAN. The mobility model, which can be used to(More)
Understanding network operation and performance issues is critical, particularly in a time when physical and virtual topologies are converging. This convergence is underscored by the adoption of cloud computing services. However, application design scenarios behave differently as do the topologies used for those applications. This paper is an investigation(More)
As more applications move to the cloud, the operation and performance of the cloud comes under greater scrutiny. In addition, educational programs incorporate more desktop and server virtualization. In trying to understand and work with this architecture, it is important to understand not only the structural change but the impact on performance metrics as(More)
A Re-examination of network address translation security" (2010). Accessed from Abstract-The use of Network Address Translation (NAT) has greatly expanded in recent years. While originally an address management technique it has often been used for security. However, there are many implementations of NAT that are inherently insecure. Recently investigation(More)
Quality of Service (QoS) techniques and protocols can be a critical part of network operations. Whether attempting to define traffic patterns, improve the performance of real time applications such as VoIP or even as part of a security strategy, QoS can be central to a network implementation. QoS topics include but are not limited to MPLS, DiffServ,(More)
