Outline Introduction Motivation Fatigue Parameters Proposed Protocol Simulation Results Conclusion 2

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. 3

Applications of WSN 4

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. 5

Types of WBASN 6

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 7

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 fatigue for each player and send live health reports to coaches and health officials during the game. 8

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

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

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. 11

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 ( 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. 12

Proposed protocol (THE-FAME) 14

15

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). 16

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

Comparison THE-FAME Direct Transmission Two parameters for fatigue calculations Six sinks deployed on the boundary of ground Threshold for lactic acid and distance covered by the player WSTM Multi-hop data Transmission No specified fatigue Parameter Single sink No threshold 18

Conclusion The proposed protocol ”THE-FAME” succeed in achieving: Better throughput Longer network life Lesser propagation delay More residual energy in the network It is suitable for: Any sport which requires constant monitoring of player’s health. People performing strenuous activities in their daily life. Patients with chronic muscle fatigue. 28
