3. Wireless Sensor Network (WSN) A WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a control center.

4. Applications of WSN

5. Wireless Body Area Sensor Network (WBASN) WBASN is a branch of Wireless Sensor Network (WSN). They use tiny sensors to monitor vital signs of human being. These sensors are either wearable or implanted into a human body.

6. Types of WBASN

7. Applications of WBASN WBASN is mainly employed for patient monitoring. WBASN can also be used in many other fields like: • Astronauts’ vital organ monitoring • Sports • Birds tracking • Cattle monitoring

8. Motivation • There is only a little research on employing WBASN in sports. • In sports, like soccer, where a team of players is on the ground, it is difficult to monitors each player’s fatigue manually. • So, we propose a protocol to constantly measure fatiguefor each player and send live health reports to coaches and health officials during the game.

9. Fatigue Parameters • Running speed of a player • Distance covered • Lactic acid level in blood

10. Running speed of a player • Soccer match usually lasts for 90 to 100 minutes. During this time players walk, jog, run and sprint.

11. Distance covered There are different types of players in a soccer team. • Attacking players • Defensive players • Mid-fielders • Goal keeper A goal keeper is very less likely to be in a fatigued state because he/she covers minimum distance during the match.

12. Lactic acid level in blood • For a normal human being the value of lactic acid level is between 4.5 to 19.8 mg/dL (0.5-2.2 mmol/L). • Where mg/dL = milligrams per deciliter and mmol/L = millimoles per liter. • When this level increases from 20 mg/dL, there is a strong chance that the player is seriously injured and need proper medical care and time to heal.

14. Proposed protocol (THE-FAME)

16. THE-FAME’s Parameters In our proposed protocol we used: • Two teams of 11 players each. • 6 sinks on the boundary of the ground. • Each player has an implanted sensor. • Threshold for lactic acid level is 20 mg/dL. • Reference Point Group Mobility Model (RPGM).

17. Compared protocol A scheme called ”Wireless sensor network for Soccer Team Monitoring [1]” (WSTM) has also done player monitoring.
