Stable High-throughput Energy Efficiency Reliable Protocol for Wireless Body Area Networks

Wireless Body Area Network (WBAN) comprises a group of sensors that monitor human physiological activities. The need for this technology has been grown rapidly due to the many applications that adopted on it, such as medical, space, and military. Because of the nature of the WBAN environment, such as the limitation in memory, computation, transceiver, the batteries that are used as an energy source and the movement of the human, many factors are restricted WBAN utilization. One of the important factors is energy consumption. Due to the limitation of resources in WBAN, designing a protocol to minimize the energy consuming and extending the lifetime of the network is a task challenge. In this paper, we proposed a high-throughput, reliable, and power efficient protocol for WBAN. A new mechanism for delivering packets to sink has been proposed. The proposed mechanism is used to ensure that all arrived packets are sent from sensors to the gateway device and to resent the dropped packets during human movement, Or link fails to increase the network reliability. Simulation outcomes of the proposed mechanism show that the minimum energy consumption maximizes the network stability period and increases network throughput. Furthermore, more packets are transmitted to the sink node, which is the main purpose of continuous human physiological activities monitoring. In comparison with two existing protocols, network stability and throughput are increased by 33%, 67%, and 55%, 45%, respectively.
