Algorithm 2: A new MN wants to connect with the BS.

1.	Start:
2.	Let $P_{i^{new}}^{m - 1} = {T_{i^{former}}^{m - 1} + T_{f}, T_{i^{former}}^{m - 1} + T_{f} + T_{p}^{l}}$
3.	For the network time is synchronized
4.	$T_{i^{new}}^{m} = T_{j^{former}}^{m - 1}$
5.	Update $P_{i^{new}}^{m - 1} = {T_{i^{new}}^{m} + T_{f}, T_{i^{new}}^{m} + T_{f} + T_{p}^{l}}$
6.	If $P_{i^{new}}^{m - 1} \cap P^{m} = ∅$
7.	Goto Label 1
8.	Else
9.	Update $T_{i^{new}}^{m - 1} = {T_{i^{new}}^{m} + T_{f}, T_{i^{new}}^{m} + T_{f} + T_{p}^{l} + T_{o}^{i^{new}}}$
10.	Adjust $T_{o}^{i^{new}}$ by TSU, to satisfy $P_{i^{new}}^{m - 1} \cap P^{m} = ∅$
11.	Label 1:
12.	Let $P_{i^{new}}^{m} = P_{i^{new}}^{m - 1}$
13.	$P^{m} = P^{m} \cup P_{i^{new}}^{m}$
14.	End
