Preprocessing This preprocessing step is done before the considered two cases of not split table traffic amounts and the split table traffic amounts. It includes the network topology design as follows: -Select the number of nodes (n) and the terrain area. -Generate randomly the locations (co-ordinates) of the n nodes using the uniform distribution. -Find the distance matrix between each node pairs. -Assume the transmission range of each node (usually all the nodes have the same range). -Find the neighbors according to the distance between nodes and the transmission range. -Determine the connectivity matrixX_(i,j), where each matrix element x_(i,j) is a Boolean variable, such that x_(i,j) =1 if there is a link from node i to node j; otherwise, x_(i,j) , = 0.

P_max , maximally allowed transmitting power of nodes.
Output variables:
y_(i,j)^(s,d) , Boolean variables, y_(i,j)^(s,d) =1 if the route from s to d goes through the link (i, j); otherwise y_(i,j)^(s,d)= 0.
Objective function:
Minimize the total power consumption of nodes. Min ∑_((i,j))▒E_(ij ) × y_( i,j)^(s,d)
Constraints:
Delay constraint: ∑_((i,j))▒y_(i,j)^(s,d) "≤ " H_(s,d) ∀ (s,d) (5)
This constraint ensures that the hop-count for each node-pair (s, d) does not exceed the pre-specified bound〖 H〗_(s,d). Bandwidth constraint:
∑_((s,d))▒∑_j▒y_(i,j)^(s,d) T_(s,d) "+" ∑_((s,d))▒∑_j▒y_(j,i)^(s,d) T_(s,d) "≤ B ∀ " i"∈ V" (6)
The availability of bandwidth along the route is ensured by this constraint.
- Transmitting power constraint: d_(i,j)^∝ x_(i,j) ≤ P_max ∀ i
This paper identifies several topics such as the type of protocols and cryptosystems used to complete online financial transactions, the development and implementation of Advanced Encryption Standard (AES), a fire control system in an automated server room, factors considered when converting general office space to a server room, and power systems in server rooms. Research indicates the use of secure hypertext transfer protocols and digital certificates for the use of online financial transactions. Additionally, AES provides:____. A fire control system requires_____. When converting general office space to a server room_____. Power options for server rooms __________.
In the process of this experiment, there were a total of two bilingual aphasics and eight monolingual aphasics who were tested through nine different EF test batteries to measure their level of EF which includes behavioural inhibition (response inhibition & interference control), working memory, planning/problem solving and reconstitution. The nine EF test batteries consists of the Stroop Color Word Test, Trail Making Test, Self-Ordered Pointing Test, Complex Figures, Wisconsin Card Sorting Test, Tower of London, Raven’s Progressive Matrices, Five Point Test and Design Fluency. The main focus of the experimentation was to test these 10 different individuals through conversation to investigate their EF profiles. To attain these results, each
Explain what happened to the CAP amplitude as voltage applied to the neuron was changed. Be specific with your results and explain why the amplitude was smaller with some voltages and larger with other voltages.
How many ancestors does a node at level n in a binary tree have? Provide justification.
I am a plate that is made of clay that was taken from the Earth of Japan. But before I was made into a plate I was up to the mountains near a big forest that had a Jinja on top a beautiful waterfall where water fell from the top to the bottom and sometimes flowing to rivers. But when winter comes the waterfall would freeze into shards and when the winter goes the shards and snow turn into water filling up the waterfall making a waterfall from the top to the bottom flowing with an immense amount of water to rivers and ponds that would sometimes connect with the waterfall. My maker crafted me to be used as art depicting many natural objects or buildings even sometimes people in the drawing. I am also used to hold a meal for a person who would eat the nourishment from top to bottom. Most of the time I would have fish from the ocean or rice that was farmed in flatlands on top of me.
holds the record as the longest serving Representative in the history of the House of Representative. 84th – 115th his term from 1955 to 2015 were the dates of service.
3) In the Drop_NoFast scenario, obtain the overlaid graph that compares Sent Segment Sequence Number with Received Segment ACK Number for Server_West. Explain the graph.
I thought this video was going to be very difficult, though we have been practicing it all semester. Once my partner and I got together to do this project I became more comfortable. I went over my weaknesses and my strengths on the previous group sessions and figured out what I need to work on and what I do well at.
Networks are designed in a number of ways, based on the geographical area, the technology used, user group specific, application based etc. But we can roughly categorize the communication networks in 2 broad categories, based on transmission: Connection-Oriented and Connectionless.
0.1 abstract In a graph theory the shortest path problem is nding a minimum path and distance between two vertices. The ap- plication in many areas of shortest path algorithms are such as geographical rout- ing, transportation, computer vision and VLSI design involve solving optimiza- tion problems on large planar graphs. To calculate the shortest path we need to know some algorithms like Kruskal's algorithm,Prim's algorithm,Dijkstra's algorithm,BellmanFord's algorithm.
This algorithm spreads the (MST) with a weighted graph that connects to it. If the graph is not connected this algorithm will get a minimum spanning tree for every disconnected edge of the graph. The set of these (MST) is called a (MSF)minimum spanning forest, which collect every vertex in the graph.
Definition. A path from node n1 to node nk is a sequence of nodes n1, n2, …, nk such that ni is the parent of ni+1 for 1 ≤ i < k. The length of a path is the number of edges in the path, not the number of nodes. Because the edges in a tree are directed, all paths are “downward”, i.e., towards leaves and away from the root. The height of a node is the length of the longest path from the node to any of its descendants. Naturally the longest path must be to a leaf node. The depth of a node is the length of the path from the root to the node. The root has depth 0. All leaf nodes have height 0.

For each of these, give a. the first IP address assigned, b. the last IP address assigned c. and the mask in the w.x.y.z/s
b) Information cannot be shared at a wider range to different receivers at distanced locations
The pathloss (LP) is the unwanted reduction in the signal strength during the propagation of the transmitted signal from the transmitter to the receiver. It relates the received signal power to the transmitted signal power. The maximum path loss is used to estimate the maximum cell range with a suitable propagation model, in GSM systems Hata Okumura propagation model is considered for calculating the maximum allowable pathloss whereas for CDMA, WCDMA and LTE networks COST 231 Hata model is considered, which is the extension of Hata-Okumura model. The Hata- Okumura Model [4] is formulated as, 44.9 6.55log log (2) ( ) [69.55 26.16log 13.82log ] h d dB L dB f h a h t p t m
