Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

Internet protocol that provides identification and location system of devices and routes traffic
across the internet
IPv6 is used to deal with problem of IPv4 address exhaustion ( protocols are not interoperable)

16. Infrastructure based IoT Protocols : 6LoWPAN

● Supports IPv6 packets over IEEE 802.15.4 WPANs.
● Low power design included - Good for battery-operated IoT devices.
● Supports applications that need wireless internet connectivity at lower data
rates for devices with very limited form factor.
● Example usage : automation and entertainment applications in home,
office and factory environments
● Challenges : management of addresses for devices that communicate
across the two dissimilar domains of IPv6 and IEEE 802.15.4 is
cumbersome
● IEEE 802.15.4 devices are intentionally constrained in form factor to reduce
costs (allowing for large-scale network of many devices), reduce power
consumption (allowing battery powered devices) and allow flexibility of
installation (e.g. small devices for body-worn networks). On the other hand,
wired nodes in the IP domain are not constrained in this way; they can be
larger and make use of mains power supplies.

model with a stack of protocols, instead of following the
standard OSI model or TCP/IP model.
Bluetooth works in the 2.4 GHz ISM band and uses
frequency hopping. With a data rate up to 3 Mbps and
maximum range of 100m.
