“…This technology is focused to create low-rate personal area networks (LR-WPAN). Its low power consumption feature make this protocol ideal for high that require secure communications, but with low data rates at short distances that maximizes the network lifetime [22]. This technology is suitable for low cost communications between nearby nodes without or with very little infrastructure.…”

Abstract-The attacks on flocks of goats and sheep are causing great economic losses in some countries. The main causes of these are usually wild animals such as wolves, or thefts of young animals. When an animal feels the presence of people or animals different than the usual ones, it experiences changes in its vital signs. The parameters which are the most altered are the heart rate and body temperature. This paper presents the development of wireless sensor nodes which can monitor vital signs of sheep and goats. These nodes form a network of wireless nodes using IEEE 802.15.4 technology. The network runs a smart algorithm able to detect episodes of collective stress on flocks of goats and sheep caused by any predator attack overnight. When the system detects changes in vital signs of animals, it sends an alarm signal to alert the person in charge of the livestock facility and activates audible and visual alarms able to scare off predators and marauders. Our system can help breeders of goats and sheep to protect their herds avoiding large economic losses that this implies.

Secondly, we investigate a number of approaches that are proposed to improve the functionality of the MAC layer in IEEE 802.15.4-based WSNs [18,19] in presence of internal interference. Thirdly, we have conducted a preliminary simulation experiment to show the influence of a set of MAC parameters on the IEEE 802.15.4 MAC functionality in the presence of intensifying internal interference.In this survey, we are interested in WBSNs that are used in medical applications.…”

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.

“…The last paper named "Fibonacci Backoff Algorithm for IEEE 802.15.4/ZigBee" by the authors Muneer Bani Yassien, Marwa Salayma, Wail Mardini, and Yaser Khamayseh presented a simulation study for the applicability of the Binary Exponential Backoff (BEB) function to compute the backoff delay for each node in IEEE 802.15.4 system [5]. Using BEB function, it is possible that two or more nodes may collide if they choose the same backoff exponent value.…”
