Privacy and Security Solution in Wireless Sensor Network for IoT in Healthcare System

Abstract

Wireless sensor networks (WSNs) are a notable study matter right now, and they're proving to be a useful tool for a variety of reasons, including ecological, defense, medical, household, and workplace apps. WSN technologies are considered to be one of the key research areas in computer science and healthcare application industries. WSNs are classified as mobile wireless sensor networks (MWSNs) or static wireless sensor networks (SWSNs). The MWSN is a specialized wireless technology with a large range of portable sensors, but the topology's uncertainty causes some performance problems across packet transmission. In the healthcare system, the sensory nodes may be static or movable depending upon the application. Due to certain limits linked with the sensor nodes, SWSNs consisting of node density with static topology face a few of the same security problems as MWSNs. The sensor node carries and forwards the data and information related to patient health, environmental conditions, medical records etc. The healthcare information system, with the help of various sensor nodes connected over the WSN, can collect, store, manage, and transmit various information related to the health sector. WSNs face numerous challenges, including security, safety, computing and power limitations, and reliability problems, particularly while routing between the nodes. To address these issues, WSN routing protocols should protect the network's security, integrity, privacy, and trustworthiness in healthcare applications. To deter network interference, effective and energy-conscious safeguards must be planned. The chapter discusses various types of WSNs, their related problems and issues, resolutions, and a node-to-node multi-hop-based stable approach for efficient routing in WSNs in various healthcare applications.
