Survey on cybersecurity issues in wireless mesh networks based eHealthcare

Abstract

Information and Communication Technologies (ICT) based applications for Ambient Assisted Living (AAL) help elderly or individual people living home alone. AAL system reliability is mostly based on the recent emerging class of network that is known as wireless mesh network (WiMesh). In WiMesh the information security is the most difficult problem to tackle because the medium is open to cyber-attacks. Moreover, when we talk about AAL where the complete personal information is digitized and stored, the need for implementation and maintenance of strict security measures is essential. In this article, we present a critical literature survey on communication security issues in e-health care environments. We highlight and explore the representative state of the art security prototypes for eHealthcare environments and also provide the details of their security characteristics. In addition, we discuss in detail the challenges and opportunities of these systems.
