| Step 1: Intiate_DummyTransact ( ) |
| { Step 1.1: Source Node broadcasts Dummy RREQ with fake Destination Address and |
| Destination Sequence Number using Send_Dummy_RREQ ( ) function. |
| Step 1.2: if (RREP = = received) |
| Mark corresponding node as Malicious Node. |
| Propagate this malicious node ID to other nodes in a network. |
| } |
| Step 2: Route Discovery Initiated by Source Node. |
| Step 3: Route Establishment by considering trust values of nodes. |
| Step 4: Packet Transmission from Source Node to Destination |
| for each node on the existing route do |
| Check Trust value (trust_val), Congestion status and Available energy level |
| If ((trust_val>0.6) andand (QS = = 0) andand (Avail_Pow > Thresh_Pow)) |
| { |
| Send DREQ to the next node in routing table and wait for DREP |
| if (DREP = = received) |
| Send data packets to the next node and wait for DR (Data Received) packet |
| if (DR = = received) |
| Mark node as trusted. |
| Update and propagate trust value of node. |
| } |

| } |
| else if (trust_val<0.6) |
| { |
| Marks node as malicious and remove from the routing table. |
| Select alternate route if available, Otherwise |
| goto Step 2. |

| re-establish route using step 2 and repeat the process. |
