Table 2 The relation between grid cells DN and GS
From: A virtual grid-based real-time data collection algorithm for industrial wireless sensor networks
DN | Relation between corresponding grid cell and GS |
|---|---|
0 | The corresponding grid cell is GS |
1 | (up side of GS)&&(right side of GS) |
2 | (up side of GS)&&(left side of GS) |
3 | (down side of GS)&&(left side of GS) |
4 | (down side of GS)&&(right side of GS) |
5 | (same column with GS)&&(up side of GS) |
6 | (same row with GS)&&(left side of GS) |
7 | (same column with GS)&&(down side of GS) |
8 | (same row with GS)&&(right side of GS) |
