The obtained results show that the proposed scheme outperforms IEEE 802.15.4 MAC in average energy consumption per information bit, thus providing a better overall performance that scales appropriately to BSNs under high traffic conditions. Within this framework, an extensive DQ MAC energy-consumption analysis in saturation conditions is presented to be able to evaluate its performance in relation to IEEE 802.5.4 MAC in highly dense BSNs. In order to emphasize IEEE 802.15.4 MAC limitations, this article presents a detailed overview of this de facto standard for Wireless Sensor Networks (WSNs, which serves as a link for the introduction and initial description of our here proposed Distributed Queuing (DQ MAC protocol for BSN scenarios.

The fact that the IEEE 802.15.4 MAC does not fully satisfy BSN requirements highlights the need for the design of new scalable MAC solutions, which guarantee low-power consumption to the maximum number of body sensors in high density areas (i.e., in saturation conditions. The hereby presented schemes always have in mind the efficient management of channel resources and the overall minimization of sensors’ energy consumption in order to prolong sensors’ battery life. For this reason, this paper aims for the optimization of Medium Access Control (MAC protocols for biomedical wireless sensor networks or wireless Body Sensor Networks (BSNs.

The space of states of initial SMS in a stationary mode is defined. the intensities of transitions from the state and in the state are equal. The physical sense of such balance is that each of SMS state in a stationary mode is in equilibrium, i.e. Such connection is defined by a system of the equations of global balance for the SMS states in a stationary mode and states of the embedded Markov's chain.

Further, the solution for PDF of this chain states is found.The second step establishes connection between the PDF of SMS states in a stationary mode and the previously received PDF of states of the embedded Markov's chain. These expressions reflect a relationship between these probabilities and the source parameters, the residence time PDF parameters, the number of each class requests, and a discipline of their service. Analytical expressions to calculate the elements of transition probability matrix in such chain are obtained. Further, for these points an embedded Markov's chain is designed, and the states space of this chain is defined. It is shown that such points are time points to complete a service of requests in SD. the non-preemptive priorities, one serving device (SD and arbitrary PDF of a residence time of each class requests.The method includes the following steps.The first step, while servicing the non-uniform population of requests, distinguishes a sequence of time points, so-called points of regeneration in which a process behaves as Markov's. The SMS has a source of requests of final capacity with exponentially distributed time of residence of different class requests in the source, one queue with discipline of requests service i.e. We discuss the implications for this on legal systems, the study of the law, and future research.įeature analysis for closed queuing system with non-preemptive prioritiesįull Text Available The object of research in this article is to obtain the analytical expressions for the probability distribution functions (PDF of states of the closed system of mass service (SMS like "model of the repairman" Mr|GIr|1 || Nr in a stationary mode.

This demonstrates that, in each of the courts examined, the vast majority of cases are resolved relatively quickly, while there remains a small number of outlier cases that take an extremely long time to resolve. Using data from the Supreme courts of the United States, Massachusetts, and Canada we show that each court's docket features a slow decay with a decreasing tail.
