Table 2 Pseudo of TIHOO. The pseudo-code of the proposed protocol. The steps of the proposed protocol are shown in this figure in detail
From: TIHOO: An Enhanced Hybrid Routing Protocol in Vehicular Ad-hoc Networks
1: Start procedure | |
2: Phase 1: Action of the source node | |
3: Set N j current node and N d destination node | |
4: While N d destination Receive Packet or (stop criterion) | |
5: Current node send Hello packet to neighbor nodes | |
6: Calculate input of fuzzy system 7: Call fuzzy logic system to limit broadcasting RREQ | |
8: Increment j | |
9: End while | |
10: Interrupt for receive RREQ of all paths | |
11: Phase 2: Action of the destination node | |
12: Get available population of N paths pi i = 1,2,...,n for Declared paths of source to destination | |
13: While i < n or (stop criterion ) | |
14: Calculate reliability factor , lifetime , buffer -available for pi | |
15: Call cuckoo search algorithm | |
16: Calculate Fitness F( pi) | |
17: Increment i | |
18: End while | |
19: Choose Optimized path is path with best fitness value | |
20 : If sending data not finished | |
21: Repeat Step 4 to Step 18 | |
22: Else if | |
23: End procedure |
