| Begin |
| Calculate the number of neighbor of ; |
| If num_neighbour = 0 then |
| Active neighbor node with probability ; |
| If num_neighbour = 1 then |
| If target and node in the same region then |
| Active this node and its neighbor node with probability ; |
| Else |
| Active neighbor node with probability ; |
| If num_neighbour ≥ 2 then |
| If there are nodes in and respectively then |
| If target in then |
| Active one node in and respectively; |
| Active one or two node in randomly; |
| Else |
| Similar to the target in ; |
| Else If there are nodes in but not in then |
| If target in then |
| If the motion of target trends to then |
| Active node inand closest the target; |
| Else |
| Active neighbor with probability ; |
| Else |
| Active one node in and respectively; |
| Else |
| Similar to the target in but not in ; |
