A Cross-Layered Design of Routing Approach for Reliable Internet of Medical Applications

Abstract

The Internet of Health Things (IoHT) comprises intelligent, low-power, tiny node sensors that monitor signals from
the body and transmit them to submerged nodes over wireless connections. IoHTs possess many uses in e-health and
private health monitoring. Due to the delicate nature of the data assessed by the devices and the power limitations of
the sensor nodes, dependability and energy efficiency are paramount in communication within IoHTs. The reliability
is compromised by the heightened loss of packets resulting from suboptimal MAC and routing algorithms, ambient
interference, and body shadows. Ineffective node choice for routing concurrently leads to a shortage of energy reserves
in crucial nodes. Recent developments in cross-layer protocol improvements have demonstrated their efficacy for
packet-based Internet. The paper proposes a Routing-based cross-layer method for secure communication that
conserves the energy resources of nodes that transmit sensors in the IoHT. The suggested methodology is expanded
to encompass multiple sensor systems, wherein nearby sensors collaborate and coordinate for data transmission. The
efficacy of the suggested technique is assessed using metrics such as Packet Loss, Delays, and energy consumption
per data packet. The findings demonstrate that the proposed solution enhances the dependability and efficiency of
energy relative to the Basic Opportunistic Routing method.
