PROJECT VIDEO
SCENARIO
1- Deploy nodes in the forest.
2- All the nodes in the equal range.
3- All the nodes that are in the one range having a one cluster head they work as a cluster coordinator.
4- Data aggregation happening on that point.
5- In the scenario first we send packet from source to destinatiosink,n when environment having no problem.
6- In the second when the fire happen that time those will detect the fire this node working as a source sent information to destination (base station).
7- Third case when fire destroy the cluster head then election algorithm elect the new cluster head and communicate with other nodes sent information to destination.
MATLAB SOURCE CODE
Instructions to run the code
1- Copy each of below codes in different M files.
2- Place all the files in same folder
3- Use the Excel files from below link and download them into the same folder as the source codes
4- Also note that these codes are not in a particular order. Copy them all and then run the program.
5- Run the “FINAL.m” file
Code 1 – Script M File – FINAL.m
