Impact of using chirp spread spectrum physical layer and request‐to‐send/clear‐to‐send combined with frame concatenation in the IEEE 802.15.4 non‐beacon enabled mode performance

IET Wireless Sensor Systems, Volume 13, Issue 1, Page 1-8, February 2023., 2023
The performance improvement of the IEEE 802.15.4 non‐beacon‐enabled mode originated by the inclusion of the Request‐To‐Send/Clear‐To‐Send (RTS/CTS) handshake mechanism is studied under IEEE 802.15.4 employing RTS/CTS. The maximum throughput and minimum delay performance are mathematically derived for both the Chirp Spread Spectrum and Direct Sequence ...

A Lightweight Three‐Party Mutual Authentication Protocol for Internet of Health Things Systems

Journal of Healthcare Engineering, Volume 2023, Issue 1, 2023., 2023
In Internet of Health Things (IoHT) systems, there is a two‐hop network structure between the authentication server TA, Internet of Things Connector (IotC), and wearable sensor (WS). Attackers can use the sensor layer network (the first hop) between the IotC and WS to steal patient’s health‐related information and undermine the security of the system ...

Performance Analysis of IEEE 802.11p Protocol in IoV under Error‐Prone Channel Conditions

Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023
The complexity of the channel condition in the Internet of vehicles (IoV) may increase the bit error rate (BER) of the intelligent vehicle terminals, resulting in data transmission failures or errors. Therefore, it is necessary to improve the performance of communication protocols under error‐prone channel conditions.

Routing Protocols in Wireless Body Area Networks: Architecture, Challenges, and Classification

Wireless Communications and Mobile Computing, Volume 2023, Issue 1, 2023., 2023
The wireless body area network (WBAN) is a branch of the wireless sensor network (WSN) intended for tracking essential patients’ physiological signals and transferring this knowledge to the coordinator. During the routing of data, WBANs encounter critical routing problems like WSNs. Moreover, the particular constraints of WBANs make it more challenging

[Retracted] Efficient and Secure Key Management and Authentication Scheme for WBSNs Using CP‐ABE and Consortium Blockchain

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
Wireless body sensor networks (WBSNs) pose significant security and privacy risks. The Medical Server (MS) will only allow legitimate stakeholders access to confidential patient medical records when successful mutual authentication between all registered users and the MS has been confirmed using preset secret attributes.

A Proposal for Network Coding with the IEEE 802.15.6 Standard

Proceedings of the 4th International Conference on Sensor Networks, 2015
We examine the Medium Access Control sublayer of the IEEE 802.15.6 Wireless Body Area Network (WBAN) standard, and propose minor modifications to the standard so that linear random network coding can be included to help improve energy efficiency and throughput of WBANs compatible with the standard.

A novel contention probability dynamism for IEEE 802.15.6 standard [PDF]

EURASIP Journal on Wireless Communications and Networking, 2014
The newly emerged IEEE 802.15.6 standard provides a multiple priority-based services for Wireless Body Area Networks (WBAN). Categorizing a node as high/low priority device leads to be assigned a relatively larger/smaller contention probability (CP), respectively.
