A Secure and Energy Efficient Resource Allocation Scheme for Wireless Body Area Network

Wireless Body Area Network (WBAN) is one of the emerging technologies, which is used to provide healthcare service by monitoring the patient's body. The WBAN has the sensors that are installed in, on or around the body that intelligently and spontaneously sense the patient's health information from the human body and it is transmitted to the hospital to provide the medical service. The major problems in heterogeneous and energy constrained WBAN system is that need high efficient energy with inadequate battery in sensor, dynamic link and because of patient's health data is sensitive it is important to give security in WBAN. To evaluate the sensor state the time slots are allocated and for security to achieve computation securely signcryption Certificateless algorithm (SCA) is used, which use homomorphic property based on bilinear cryptosystem. The experimental result discuss about low computational cost, low energy efficiency.
