Wireless Sensor Node Simulation

Step 1: create a network topology .it consists 100- sensor nodes and 1-BS. Step 2 : Choose 10 Node to BE Cluster Heads step 3: next, in BS generate random key name it network key Step 4: BS assign (Random key to all cluster head) and use this ID to generate Cluster head key by (Network Key XOR CH id) and sends it to all Cluster heads. Also generate initial seeds for PRNG and send it tol all clusters also Each cluster head send these information to all sensor in the cluster ( cluster head key, initial seeds). Step 5: next,in sensor nodes generate 2 HMAC (using the cluster head key) from sensed data. Sensor node inject the 2 HMAC into random position (the positions generated from PRNG) into the data Step 6: next, the sensor node transfer the data with 2 HMAC value and seed value to the CH. Step 7: next in CH extract the injected 2 HMAC with their positions and compare the one extracted with the one produced if equal then : 1-aggregate this data with other verified data from other sensors in the same cluster 2-generate new watermark from the aggregated data and inject it 3- send it to the base station if not equal add node id to blocked list and also send it to base station Step 8: Perform the data transmission to next Cluster head until based station Step 9: plot the results graph for energy consumption , throughput, PDR - packet delivery ratio, delay
