This is an implementation of the Hirschberg-Sinclair Leader election algorithm. It's written in Java and uses Java RMI for communication between Nodes.
This was developed on a Mac running Mac OS X 10.7.3
The build and run script uses osascript to open a terminal window for the Ringer process, and n terminal windows for n Node processes.
You can choose to not have any terminal windows for the Node processes by editing the run-hs file. Inside the file is documentation to help you do that.
The build script also generates a new java security policy file from java.policy.default that gives file writing, reading and executing permission for the current working directory.
run.sh automatically places the current working directory in the appropriate place in the policy file and outputs the new file as java-security.policy.
Since for this project I was required to keep track of average number of messages sent by nodes, I have some reporting functionality that writes a file named stat.txt.
This file contains a record of runs of this algorithm with the node count and average messages sent and average messages received.
To run the algorithm:
$ ./run-hs <number of nodes>
