Part 1
You are required to implement Dijkstra's Single Source Shortest Path (ssp) algorithm for undirected graphs using Fibonacci heaps. You must use the adjacency list representation for graphs.
Part 2
You are required to implement a routing scheme (routing) for a network. Each router has an IP
address and packets are forwarded to the next hop router by longest prefix matching using a binary trie. For each router R in the network, call ssp implemented in Part 1 to obtain shortest path from R to each destination router Y. To construct the router table for R, for each destination Y, examine the shortest path from R to Y and determine the router Z just after R on this path. This gives you a set of pairs <IP address of Y, next-hop router Z>. Insert these pairs into a
binary trie. Finally, do a postorder traversal, removing subtries in which the next hop is the same for all destinations. Thus, multiple destinations having a prefix match and the same next hop will be grouped together in the trie.
2. Input/Output Requirements
You may implement this assignment in Java or C++. Your program must be compilable and runable on the Thunder CISE server using gcc/g++ or standard JDK. You may access the server using Telnet or SSH client on thunder.cise.ufl.edu.
You must write a makefile document which creates two executables. The names of your executables must be ssp and routing.
Hi there
I'm a senior software developer who have about 200 completed projects and my account was qualified by this site (my page: https://www.freelancer.com/u/DucNA.html).
Btw, could you please send (or discuss with) me more detail? I'll check and then will let you know my estimation (time and coding effort) for this task.
Best regards,
Duc Nguyen
Hi I have implemented both fibonacci heaps, red black trees and AVL trees all using JAVA as well as graph traversal algorithms inclusing shortest paths. I can do this for you to your satisfaction.
Hi
I am an experienced C/C++/Java developer with good knowledge on data structures and algorithms including graphs. I will be happy to work on this project according to the requirements and promise to deliver quality work.
My work experience includes internship at Google(2012) and working with several start-ups in Kenya to deliver android mobile and web solutions.
Thanks and regards,
Isaac
hello.
I saw your description and attached files.
I understand it and can do it .
I have done several project like this.
I'm an expert in Data Mining, Data Structures and Algorithms.
And I know Java ,C/C++ and Python well.
I'm interested this project.
I want to discuss with you about this project.
If it's possible,please contact me and explain more detail.
I wait your good reply.
Bye.
Hi, I've been developing in JAVA for 18 months and I have developed algorithms you need already in the past. Though that implementation was in C++. I already have experience and expertise one needs to do this assignment and would be glad to do this job.
I usually prefer JAVA and will import my previous implementation (of djikstra algorithm with adjacency list) to JAVA. Not to mention, using that I'll cover the second implementation that you need. I also have strong understanding of network layouts and it won't be a problem to build a router table using the djikstra.
Contact me if you are interested or if want to discuss it further.
Thanks.
