Algorithm 3Reception phase: IoB-DTN based on data aggregation.

1:
On reception of packet $p \cup N \cup L$ (list of neighbors)
2:
$p o s \leftarrow$ self position in L
3:
$N^{'} \leftarrow \frac{N}{2^{p o s + 1}}$
4:
if ( $Δ$ (p, $p^{'}$ ) < ( $Δ$ area || $Δ$ period || ( $Δ$ area + $Δ$ period) ) ) then
5:
Aggregate p with the packet $p^{'}$
6:
else
7:
if Buffer management provides a slot and $N^{'} \geq 1$ then
8:
Store $p \cup N^{'}$
9:
Send ACK for receiving $N^{'}$ copies of p
10:
else
11:
Packet is rejected, no ACK is sent
12:
end if
13:
end if
