A survey of IEEE 802.15.4 effective system parameters for wireless body sensor networks

Abstract

SUMMARYWireless body sensor networks are offered to meet the requirements of a diverse set of applications such as health-related and well-being applications. For instance, they are deployed to measure, fetch and collect human body vital signs. Such information could be further used for diagnosis and monitoring of medical conditions. IEEE 802.15.4 is arguably considered as a well-designed standard protocol to address the need for low-rate, low-power and low-cost wireless body sensor networks. Apart from the vast deployment of this technology, there are still some challenges and issues related to the performance of the medium access control (MAC) protocol of this standard that are required to be addressed. This paper comprises two main parts. In the first part, the survey has provided a thorough assessment of IEEE 802.15.4 MAC protocol performance where its functionality is evaluated considering a range of effective system parameters, that is, some of the MAC and application parameters and the impact of mutual interference. The second part of this paper is about conducting a simulation study to determine the influence of varying values of the system parameters on IEEE 802.15.4 performance gains. More specifically, we explore the dependability level of IEEE 802.5.4 performance gains on a candidate set of system parameters. Finally, this paper highlights the tangible needs to conduct more investigations on particular aspect(s) of IEEE 802.15.4 MAC protocol.

Improving Route Selections in ZigBee Wireless Sensor Networks

“…The IEEE 802.15.4 MAC layer has two operation modes: beacon and beaconless modes [3,29,30]. In this paper, we focus on the beaconless mode, which is more suitable for multihop communications.…”

“…In this study, we considered the default parameters of the ZigBee network layer and the IEEE 802.15.4 MAC and physical layers. Given that the performance of these systems can vary with such parameters [29,30], it would be interesting to study whether the results reported here could be improved by optimizing such parameters.…”

An effective approach for energy aware in wireless sensor network

“…The LRWPANs is used in many applications and many fields such as agriculture, environment monitoring, security purposes, military, sports ( [6], [7]) as well as entertainments [8]. In healthcare fields [9], the technology of IEEE 802.15.4 is so used in order to supervise the humans parameters [10] like the cardiac patients monitoring [11].…”

Improving reliability performance of diffusion‐based molecular communication with adaptive threshold variation algorithm

“…A promising application of MC is to organize intra‐body nano‐network for purpose of health monitory and drug delivery . Nano‐network motivated by MC may achieve better performance than traditional wireless sensor network considering the serious fading of electromagnetic wave in intra‐body environment …”

“…2 Nano-network motivated by MC may achieve better performance than traditional wireless sensor network considering the serious fading of electromagnetic wave in intra-body environment. 3,4 Among various proposed mechanisms of MC in literatures, this paper focuses on diffusion-based MC as it represents a general biological architecture of MC in nature and widely investigated background in academia. In diffusion-based MC, molecules are emitted by the transmitter, propagate in the medium via diffusion, and eventually reach the receiver.…”
