“…However, for low data rate applications and when energy constraint is more important than bandwidth constraint, NC-MFSK modulation scheme with lower order constellation (lower M) is an attractive option. Several papers have appeared in the literature that deal with energy efficiency and reliability issues in WBANs [8][9][10][11][12][13][14][15]. In [8], the author considers optimal power allocation to improve the energy efficiency of WBANs with constraints on outage probability.…”

Selection of the most energy-efficient modulation scheme is vital for wireless body area networks (WBANs) for improving the network lifetime. In this paper, we investigate the performance of various modulation schemes specified by IEEE 802.15.6 WBAN standard, in terms of energy consumed for successfully transferring one packet from the sensor node to the hub. Assuming a contention-free MAC protocol, we present an analytical model for computing the energy consumption for a given modulation scheme both for uncoded transmission as well as transmission using Bose-Chaudhuri-Hocquengham (BCH) codes; the coding scheme specified by IEEE 802.15.6 for WBAN. The following communication scenarios specific to a WBAN are considered: (i) in-body communication between invasive devices and hub and (ii) on-body communication among non-invasive devices and hub with line-of-sight (LOS) and non-LOS (NLOS) channels. The results show that the use of higher order differential phase shift keying (D8PSK)-based modulation schemes results in significant reduction of total energy consumption. When BCH codes with various code rate specifications are used, total energy consumption remains lower for the higher order modulation schemes. The energy consumption is further reduced when non-coherent frequency shift keying (NC-MFSK) is employed as an alternate modulation scheme instead of differential PSK schemes.

Abstract-This paper investigates cooperative relaying to support energy efficient in vivo communications. In such a network, the in vivo source nodes transmit their sensing information to an on-body destination node either via direct communications or by employing on-body cooperative relay nodes in order to promote energy efficiency. Two relay modes are investigated, namely single-hop and multi-hop (two-hop) relaying. In this context, the paper objective is to select the optimal transmission mode (direct, single-hop, or two-hop relaying) and relay assignment (if cooperative relaying is adopted) for each source node that results in the minimum per bit average energy consumption for the in vivo network. The problem is formulated as a binary program that can be efficiently solved using commercial optimization solvers. Numerical results demonstrate the significant improvement in energy consumption and quality-of-service (QoS) support when multi-hop communication is adopted.Index Terms-Body area network, in vivo, energy efficiency, relaying, multi-hop. I. INTRODUCTIONNowadays, health care systems demand accurate and continuous monitoring of patients' health status. Such a monitoring is currently enabled through wireless body area networks that adopt low-powered sensor nodes which can be deployed inside the human body (in vivo) or on the body to measure all physiological data of interest.A major challenge for in vivo communication is the requirement to support energy efficient communications with a quality-of-service (QoS) guarantee. This objective is motivated by the low power supply available for the in vivo sensor nodes and the associated difficulties with replacing the batteries of the in vivo implanted nodes. In most cases, it may not be feasible to support energy efficient in vivo communication given the high path loss, which may also lead to QoS outage. As a result, deploying on-body relay nodes can result in satisfying the target QoS and energy efficiency requirements. Thus, multiple in vivo sensor nodes can use multiple on-body relay nodes to forward the physiological signal information towards an on-body destination node that further transmits all gathered information to the hospital server for continuous monitoring and processing. Furthermore, a single on-body relay node can be used by multiple in vivo source nodes through a frequency division multiple access (FDMA) scheme among source nodes. However, most of the existing research focus mainly on singlehop relaying. On the other hand, multi-hop relaying can further

Wireless sensor network (WSN) is a well-developed domain suitable in the optimal collection and processing of information needed for the present world. For processing and transmitting the correct data by the network, it is affected by many disrupting factors like interference, battery life, distance between the nodes, and redundant data. There have been many methods proposed in the past. Among all the disrupting factors, routing has been the most studied problem in the WSN literature, whereas packet length sizing has been the most untouched topic compared to routing. Sizing the packet lengths to transmit it through the network is important to get error-free data and run an energyefficient network. In this paper, we propose a sling-shot spider optimization (S 2 SO) algorithm for packet length optimization in WSN and Internet of Things (IoT)-based networks. The S 2 SO algorithm is developed based on the spider's unique behavior of catching prey. The proposed algorithm is implemented in three types of networks: 1-hop, 2-hop, and multi-hop networks. A mathematical model for the communication channel, energy efficiency, and energy consumption is developed for all three types of networks.The proposed packet length optimization model is simulated in MATLAB software and compared with conventional bio-inspired algorithms. The results show that the proposed algorithm is very fast in finding the optimal results and transmits optimal packet size with low error rate of 0.2 p.u. and a high efficiency of 98%.
