A Novel Anchorless Node Positioning Method for Wireless Sensor Network

Algorithm 2

Ordinary node positioning process.

The steps of ordinary node positioning

Input: Received beacon frames: beacon = {φ,,H,L_BS};

Output: Node coordinates:(x,y);

Steps:

1: while(1)

2:  Node in listening state;

3:  recv ← Received data frames;

4:  if(recv is the end frame)

5:   break;

6:  else //Indicates beacon frames

7:   if(recv≥1)

8:    if(recv>1)

9:     ,

10:    endif

11:    

12:    Node polar coordinates: (ρ,φ)

13:    (x,y)←(ρ,φ)

14:   endif

15:  endif

16: endwhile
