A novel energy-efficient framework (NEEF) for the wireless body sensor network

Increasing the availability of wireless body sensor network is obligatory to monitor the patient inside and outside the hospital environment. Major amount of energy dissipated in the sensor node is through the enormous switching transitions in the transceiving unit, and hence, it becomes essential to minimize the switching transitions to prolong the lifetime of the network. Also, the packet holding cost in terms of energy influences the network lifetime to a greater extent. The novel energy-efficient framework (NEEF) approach provides a solution for lifetime problem and availability problem in the network. The subject is modeled as finite state machine with normal, abnormal and above normal states. The packet in the cluster head is transmitted once it reaches the threshold level. The critical packet is hoped through high energy node to ensure safe data communication. The framework is evaluated with Fail Safe Fault Tolerant algorithm. The lifetime enhancement is achieved through reducing the switching loss of the transceivers circuit. The NEEF provides extended lifetime and throughput and the framework also promotes improved half-life period. The first dead node in case of NEEF framework is high. The NEEF ensures high availability and extended lifetime.
