An Energy-Aware Data Transmission Scheme under the Guarantee of Reliability for 3D WSNs

Algorithm 1.

An energy-aware transmission scheme for 3D WSN.

1 Begin

2  // the network boundary

3  // the total number of nodes

4  // : The required network reliability

5  for each source node:

6   djuge the node in near area or far area

7   if node in far area

8    calculates following equation (31)

9   initiates packet copies and sends them per interval to the next hop

10   if the packet successfully transmitted to the next hop and the next hop in far area

11    go to step 9

12   else if the successfully relayed next hop in near area

13    

14    while

15    sends one data packet and waits for an ACK

16    if node does not receive the returned ACK

17     ;

18    else

19     break;

20    end

21   end

22   else record the packet is lost

23  end

24 else

25  calculates following equation (23)
