Wireless body area network has been implemented to monitor the human body systems to detect and cure the diseases. Lifetime and Latency are the major concerns in for Wireless body area network. Due to the signal transmission takes place in or around the body in WBAN, Packet Error Rate has been affected because of channel fading and collisions in the channel due to the existence of other wireless devices. Therefore, latency and lifetime of the sensors very crucial. To reduce these issues, cognitive radio (CR) armed Wireless body area network should be a better option. Here, Reed Solomon and LDPC error correcting mechanism for CR-armed Wireless body area network has been proposed. Various issues in Cognitive Radio networks have been investigated till date to cope with latency and energy utilization. Error control techniques have not explored for Cognitive Radio networks and the existing error correcting mechanism for WSNs should not be imposed to Cognitive Radio network due to the mechanism of adaptive spectrum access mechanism. The method proposed here selects the routes and number of hops from source to sink adaptively and alters the redundancy to reduce the expected energy and latency utilization. The simulation results show that the proposed mechanism gives better results with the view of energy, latency consumption in the multihop CR armed Wireless body area network.
