Key Resynchronizing in Low Power Wide Area Networks

LPWANs are a class of technologies that have very low power consumption and high range of communication. Along with its various advantages, these technologies also have many limitations, such as low bandwidth, connectionless transmission and low processing power, which has challenged encryption methods in this technologies. One of the most important of these challenges is encryption. The very s...

Communications-Efficient Multithreading on Wide-Area Networks

This paper shows how to run multithreaded programs on a DRAM (Distributed Random Access Memory) parallel computer and demonstrates that such programs can run efficiently on a collection of machines distributed across thousands of miles over the internet. Suppose we have a fully strict multithreaded program has work and critical-path length , and we have a processor DRAM machine with an upper bo...

Quorum Placement on Wide-Area Networks

Content distribution networks are the dominant technology for distributing shared media on todays Internet. There are several types of content for which these systems have been proven highly successful: static databases, streaming media, online gaming. At the same time this architecture is not appropriate for other types of applications such as transactional databases that require both strong c...

On Scaling Software-Defined Networking in Wide-Area Networks

Software-Defined Networking (SDN) has emerged as a promising direction for next-generation network design. Due to its clean-slate and highly flexible design, it is believed to be the foundational principle for designing network architectures and improving their flexibility, resilience, reliability, and security. As the technology matures, research in both industry and academia has designed a co...

On QoS Multicasting Performance in Wide Area Networks

| Multicasting enables applications to scale to a large number of users without overloading the network and server resources. With the advent of multimedia applications , the focus of multicasting research has shifted from minimizing the overall cost of the multicast tree to nding one which supports the QoS requirements of the underlying multimedia application. Finding such a tree, however, is ...
