AB  - The need for communication becomes mandatory during critical conditions of the patient. The
wireless body sensor node dies due to its power starving nature and becomes unavailable when it is in need.
Considering this problem, the lifetime of the network has been increased by choosing relay node based on the
energy status of the relay node. The patient state is classified into normal and abnormal state based on the data
from the sensor. The data from the HB and ECG signal are cross correlated with the patient reference signal. The
patient state is realized as a Finite State Machine (FSM) and analyzed with markov model. Under abnormal
condition the network is realized as star topology and all sensors are awakened and close monitoring is done.
The node reserves a part of energy for monitoring critical condition of patient. The proposed Energy Efficient
Routing Solution (EERS) is compared with existing protocols. The algorithm outperforms the other algorithm
in terms of lifetime by 1.26 times, throughput by 1.12, when compared with M-ATTEMPT and avoid energy hole
problem. The algorithm serves to be the better solution for uninterrupted monitoring of patient in critical
condition.
