“…When sender discovers that data has been lost in the network, it retransmits the missing packets to recover the data, which further causes retransmission overhead problem. Recovering from losses can be done either applying timer-driven retransmission or data-driven retransmission [3] [6]. In Timedriven recovery, if a sender does not receive a positive cumulative ACK for a packet within a certain time-out interval, it retransmits the missing data.…”

Wireless Body Area Network (WBAN) is a special kind of sensor network deployed with low power, intelligent sensors, which are placed on the human body to collect human's vital signs, while monitoring body functions and the surrounding environment. Many applications of WBAN demand Reliable communication service; since the majority of these applications are responsible for handling time-critical data. Such an application area is a healthcare system, which offers flexibility and mobility to patients through the internet. Due to the long propagation delay and high loss rate in the WBAN, it is very tough to provide reliable data transfer for time-critical applications. In this paper, we analyze all these issues and design an efficient Reliable Delay Sensitive Loss Recovery protocol (RDSLR) for handling critical and non-critical data in WBAN. We emphasize on arrival of heterogeneous data (i.e. traffic flow) within the expected time for the analysis of actual health conditions of a patient. Reliable and loss-free data transmission requirements in a healthcare system desire arrival of data within the predefined critical time interval. Thereby, we enhance the loss recovery and delay module considering critical time parameters as an account. We evaluate the performance of the proposed approach by taking packet loss rate, elapse time, loss error time, and reliability time as key metrics.

“…The main job of WBAN is to continuously monitor health data and send it to healthcare server. Dynamic and heterogeneous nature of healthcare WBAN makes Quality of Service (QoS) provisioning very inspiring and essential research facet [1][2]. In healthcare WBAN system reliable data transmission [10][11] with low delay [15] is very important, to improve the quality of life and to reduce treatment cost.…”

With growth in population and diseases, there is a need for monitoring and curing of patients with low cost for various health issues. Due to life threatening conditions, loss-free and timely sending of data is an essential factor for healthcare WBAN. Health data needs to transmit through reliable connection and with minimum delay, but designing a reliable, and congestion and delay free transport protocol is a challenging area in Wireless Body Area Networks (WBANs). Generally, transport layer is responsible for congestion control and reliable packet delivery. Congestion is a critical issue in the healthcare system. It not only increases loss and delay ratio but also raise a number of retransmissions and packet drop rates, which hampers Quality of Service (QoS). Thus, to meet the QoS requirements of healthcare WBANs, a reliable and fair transport protocol is mandatory. This motivates us to design a new protocol, which provides loss, delay and congestion free transmission of heterogeneous data. In this paper, we present a Dynamic priority based Quality of Service management protocol which not only controls the congestion in the network but also provides a reliable transmission with timely delivery of the packet.

“…Most of these protocols were designed to avoid rise of temperature in the sensor nodes by relaying traffic routing to specific nodes and fusing data to reduce the number of packet transmissions. Regarding the transport layer, protocols have been designed to avoid energy waste resulting from congestions and bottlenecks that could impact the packet loss ratio (PLR) and the latency of communication [12]. In the application layer, the energy aware protocols focus on the compression of data, data fusion and data aggregation techniques to reduce the number of transmissions [13,14].…”

An efficient cross-layer approach should provide schemes to avoid all the aforementioned sources of energy waste by promoting novel trade-offs between layers to enhance the wireless communication process and simultaneously extend the network lifetime. Taxonomy: cross-layer approaches for WBANsIn this section, the different studies are classified by the communication layers involved in each cross-layer strategy. This survey details how each approach works (as described by the authors in the original paper), its main problems and shortcomings that represent open issues for future research, and a critical analysis of the performance results as originally presented by the authors.
