The combination of this is useful method for one step ahead to increase the life of human being on this world. The issue is to increase the growth of all this living mankind from different serious diseases, so the technology and communication is BAN (Body Area Network) through wireless is Wireless Body Area Network. We do the research on the adaptive energy efficient Medium Access Control protocol used in WBAN, so to increase the life of sensor node. Once the energy is utilized we cannot extend its energy only by replacing the battery. Proposed protocol incorporates dynamic duty cycle as well as adaptive contention window schemes. We have simulated the protocol in NS2 environment and checked the performance of data transmission in different condition may be in Normal, On-demand and Traffic which leads to consume more energy.

TL;DR: A cross-layer routing mechanism for WBAN quality of service enhancement using a cost function, which linearly combines node energy ratio, link reliability, and specific absorption rate functions, is proposed.
Abstract: Wireless body area networks (WBAN) require long life links and energy efficient system. Besides the increasing commercialization of WBAN, health monitoring applications calls for enhanced quality of service (QoS). The establishment of the reliable and energy efficient link is crucial to support the improvement of the WBAN performance parameters. In this article, we propose a cross-layer routing mechanism for WBAN quality of service enhancement. The protocol uses a cost function, which linearly combines node energy ratio, link reliability, and specific absorption rate functions. The proposed algorithm initially maximizes network lifetime longevity by reducing node energy consumption with nearly reasonable throughput and the packet delivery ratio whereas the enhancement of the QoS focused on improving network throughput and the packet delivery success rate for WBAN applications. The algorithm is implemented in two stages, firstly by designing the energy efficient and reliable link routing policy in the network layer and secondly the adjustment of the contention window for QoS performance enhancement in the data link layer using IEEE 802.11 medium access control (MAC) protocol. We conduct parametric modeling of the cost function to analyze network performance in different parametric combinations and contention window adjustments. Simulation results show the proposed protocol improves network performance indicators such as energy efficiency, lifetime longevity maximization, throughput, and packet success delivery ratio.

TL;DR: A frame structure model of a self-adaptive guard band (SAGB) protocol is proposed, which introduces a guard band in each time slot according to the allowed maximum time drift of the crystal, adaptively adjusts the value of the GB based on the actual time drift, and then ensures that the node simultaneously maintains the sleeping state and synchronization with the coordinator during beacon transmission, thus reducing the energy consumption.
Abstract: Body area networks (BAN) are at the forefront of technologies for long-term monitoring of personal healthcare, which is intended be an effective strategy to address the aging population worldwide. The transceiver is the most energy-consuming part of a sensor node, and radio transmission in the vicinity of the human body is highly lossy and inefficient. Therefore, the energy of the sensor node constrains the life cycle and quality of service (QoS) of the network; consequently, low-cost protocol shave attracted wide interest. This paper proposes a frame structure model of a self-adaptive guard band (SAGB) protocol, which introduces a guard band (GB) in each time slot according to the allowed maximum time drift of the crystal, adaptively adjusts the value of the GB based on the actual time drift, and then ensures that the node simultaneously maintains the sleeping state and synchronization with the coordinator during beacon transmission, thus reducing the energy consumption.

TL;DR: An attempt has been made to enhance the system existence with smart clustering component by dissecting the Connectivity, Distance and Residual proficiencies by indicating as far as possible for number of nodes in the cluster.
Abstract: The principle issue with existing convention lies in the arbitrary choice of cluster heads. There exists a likelihood that the cluster heads structured are unequal and may stay in one part of the system making another part of the system inaccessible. In this work an attempt has been made to enhance the system existence with smart clustering component by dissecting the Connectivity, Distance and Residual proficiencies. The work will additionally decrease the rate of getting a particular node dead, rapidly. The proposed scheme will similarly control the amount of clusters in the system by indicating as far as possible for number of nodes in the cluster. This work will give an attractive balanced circulation of cluster and also sensor nodes over the system.

TL;DR: In this chapter, IoT based CR network in uplink communication is proposed alongside employing NOMA techniques for optimal throughput, and energy efficiency for a medical infrastructure.
Abstract: It has become very essential to address the limited spectrum capacity and their efficient utilization to support the increasing number of Internet of Things devices. When it comes to medical infrastructure, it becomes very imperative for medical devices to communicate with the base station. In such situations, communication over the wireless medium must provide optimized throughput (data rate) with effectual energy usage, which will ensure precise medical feedback by the responsible staff. Taking into account, it is necessary to operate wireless communication precisely at a higher frequency with more substantial bandwidth and low latency. Cognitive Radio (CR) is traditionally a viable choice, where it identifies and utilizes the vacant spectrum, thus maximizing the primary user's capacity and achieving spectral efficiency. To ensure such outcomes, the Non-Orthogonal Multiple Access (NOMA) techniques have proven to deliver an effective solution to the increasing number of devices with unimpaired performance, especially when the communication shifts towards a higher frequency band such as the mmWave band. In this chapter, IoT based CR network in uplink communication is proposed alongside employing NOMA techniques for optimal throughput, and energy efficiency for a medical infrastructure. Numerical results show that effectual throughput and energy efficiency for a High Reliable Communication (HRC) device and Moderate Reliable Communication (MRC) device improve over 83.13% and 73.95%, respectively and their corresponding energy efficacy values show vast improvement (83.11% and 73.96% respectively). Likewise, for interference case both the throughput and the energy efficiency improve approximately over 93% for all devices.

TL;DR: This paper investigates the WiseMAC protocol with different important schemes that are used in implementation of Wise MAC in sensor networks, and adaptive Wise MAC protocol with dynamic duty cycle and the adaptive Contention Window is proposed.
Abstract: Recent few years are proved very progressive in terms of energy efficient protocols in Wireless Sensor Networks, but energy efficiency is still a point of focus in sensor networks. Among various MAC layer protocols, Wise MAC is known as one of the most energy efficient protocols. Non-Persistent Carrier Sense Multiple Access (NP-CSMA) and the preamble sampling are the main techniques used in basic Wise MAC protocol. Basically they are used to reduce the power consumption when energy is wasted in listening to idle medium. This paper investigates the Wise MAC protocol with different important schemes that are used in implementation of Wise MAC in sensor networks. These schemes basically emphasize on energy saving methods in Wise MAC. Various modifications are done to the original Wise MAC to make it more energy efficient, with the same motive of increasing energy efficiency, adaptive Wise MAC protocol with dynamic duty cycle and the adaptive Contention Window is proposed.
