CPAOR: Control Packet Aware On-Demand Routing Protocol for WBANs

The core problem of the WBANs nodes is the limited energy resource. Consequently, an energy-efficient routing protocol is very critical in this type of network. A major drawback of the current routing protocols is that they do not take into account the monitoring of a large number of patients. So, this is a problem in the event of disasters. In addition, mostly routing algorithms fail to take into account balancing the energy consumption between nodes. Furthermore, routing overhead and reduced complexity are also highly required in this type of network. In this paper, we propose Control Packet Aware On-Demand Routing (CPAOR) protocol to overcome the mentioned drawbacks. The proposed protocol decreases the number of control packets and adds awareness to the transmission of control packets. This solution enhances the network lifetime. The simulation results of the CPAOR protocol are analyzed and examined using MATLAB, in terms of energy consumption, energy factor, routing overhead, and changing the number of nodes to more than 60 nodes. CPAOR protocol showed an improvement of 70.9% than the DMQoS, ORACE-Net, and DLQoS protocols in terms of energy consumption. This proves CPAOR to be an efficient routing protocol for WBANs. The CPAOR protocol has proven to be an effective routing protocol for WBANs.
