“…Many studies on multi-hop WBANs have focused on energy-efficient MAC or routing protocols [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. For example, previous studies have focused on a cross-layer technique that includes a MAC layer to reduce delay and improve energy efficiency [ 23 , 24 , 25 ]. In [ 23 ], a network tree in a distributed manner has been used to guarantee collision free access to the medium and to route data towards the sink.…”

The performance of a quality of service (QoS) control scheme in a multi-hop wireless body area network (WBAN) based on the IEEE Std. 802.15.6 is evaluated. In medical Internet of Things systems, WBANs are an important technology. In a previous study, an optimal quality of service control scheme that employs a multiplexing layer for priority scheduling and a decomposable error control coding scheme for WBANs were proposed. However, the two-hop extension supported by IEEE Std.802.15.6 has not been considered. Here, the two-hop extension is applied. Then, the packet error ratio, number of transmissions, and energy efficiency of our previously proposed system are compared to a standard scheme under several conditions. Also, novel evaluations based on communication distance are conducted. Numerical results demonstrate that our proposed scheme, in which coding rates change relative to channel conditions, outperforms standard schemes in many aspects. In addition, those systems show the best performance when the communication distance of the first hop equals that of the second hop. In addition, the above result is theoretically clarified.

“…Simulation results show that the proposed recovery algorithm increases the energy efficiency of conventional CS-based reconstruction methods. A cooperative WBAN protocol is proposed in [ 12 ], which is able to support multi-hop communication along with cooperation. This protocol extends cooperation at the MAC layer to cross-layered gradient-based routing.…”

In this study, we analyse incremental cooperative communication for wireless body area networks (WBANs) with different numbers of relays. Energy efficiency (EE) and the packet error rate (PER) are investigated for different schemes. We propose a new cooperative communication scheme with three-stage relaying and compare it to existing schemes. Our proposed scheme provides reliable communication with less PER at the cost of surplus energy consumption. Analytical expressions for the EE of the proposed three-stage cooperative communication scheme are also derived, taking into account the effect of PER. Later on, the proposed three-stage incremental cooperation is implemented in a network layer protocol; enhanced incremental cooperative critical data transmission in emergencies for static WBANs (EInCo-CEStat). Extensive simulations are conducted to validate the proposed scheme. Results of incremental relay-based cooperative communication protocols are compared to two existing cooperative routing protocols: cooperative critical data transmission in emergencies for static WBANs (Co-CEStat) and InCo-CEStat. It is observed from the simulation results that incremental relay-based cooperation is more energy efficient than the existing conventional cooperation protocol, Co-CEStat. The results also reveal that EInCo-CEStat proves to be more reliable with less PER and higher throughput than both of the counterpart protocols. However, InCo-CEStat has less throughput with a greater stability period and network lifetime. Due to the availability of more redundant links, EInCo-CEStat achieves a reduced packet drop rate at the cost of increased energy consumption.

“…This section gives an overview of the works related to relationship between physical and physiological parameters and integration of WSNs with the cloud computing paradigm. Ivanov et al [9] has proposed a co-operative WBAN environment that supports multi hop transmission through cooperative WSNs and WBAN nodes. The essentiality of considering the values of both environmental parameters and WBAN nodes for deciding the comfort of a person is discussed.…”

The number and type of sensors measuring physical and physiological parameters have seen dramatic increase due to progress in the MEMS and Nano Technology. The Wireless Sensor Networks (WSNs) in turn is bringing new applications in environment monitoring and healthcare in order to improve the quality of service especially in hospitals. The adequacy of WSNs to gather critical information has provided solution but with limited storage, computation and scalability. This limitation is addressed by integrating WSN with cloud services. But, once the data enters the cloud the owner has no control over it. Hence confidentiality and integrity of the data being stored in the cloud are compromised. In this proposed work, secure sensor-cloud architecture for the applications in healthcare is implemented by integrating two different clouds. The sink node of WSN outsources data into the cloud after performing operations to secure the data. Since the SaaS and IaaS environments of Cloud Computing are provided by two different cloud service providers (CSPs), both the CSPs will not have complete information of the architecture. This provides inherent security as data storage and data processing are done on different clouds.
