There has been an increase in research interest in wireless sensor networks WSNs as a result of the potential for their widespread use in many different areas like home automation, security, environmental monitoring, and many more. Despite the successes gained, the widespread adoption of WSNs particularly in remote and inaccessible places where their use is most beneficial is hampered by the major challenge of limited energy, being in most instances battery powered.

A new wake-up radio architecture for wireless sensor networks

Wireless body area networks WBANs are severely energy constrained, and how to improve the energy efficiency so as to prolong the network lifetime as long as possible is one of the most important goals of WBAN research. Low data-rate WBANs are promising to cut down the energy consumption and extend the network lifetime. Longer superframes are exploited to cut down the energy consumed on the transmissions and receptions of redundant beacon frames. Insertion time slots are embedded into the inactive part of a superframe to deliver the frames and satisfy the quality of service QoS requirements. The number of the data subsections in an insertion time slot can be adaptively adjusted so as to accommodate low data-rate WBANs with different traffic. Simulation results show that the proposed MAC protocol performs well under the condition of low data-rate monitoring traffic.

of a long preamble and overhearing in such protocols as RF Wake-up and B-​MAC. There are various low duty cycle protocols proposed for WSNs which differ in aspects of the concept of passive clustering (Gerla et al., ) where nodes are Features an extensive website with the bibliography, PowerPoint slides.


Low Duty-Cycling MAC Protocol for Low Data-Rate Medical Wireless Body Area Networks

Show all documents In this MPTC, active vector duration can be done by three different ways first one is torque ripple minimization and second one least square optimization and the third one is dead beat control. Torque ripple which is used to calculate the optimal weighting factor and the control period is divided into two intervals to achieve further torque ripple reduction. The equation to obtain the optimal weighting factor is complicated and parameter dependent.

Prolonging the Lifetime of Wireless Sensor Networks: A Review of Current Techniques

Он потребовал, чтобы я публично, перед всем миром, рассказал о том, что у нас есть ТРАНСТЕКСТ. Он сказал, что, если мы признаем, что можем читать электронную почту граждан, он уничтожит Цифровую крепость. Сьюзан смотрела на него с сомнением. Стратмор пожал плечами: - Так или иначе, уже слишком поздно. Он разместил бесплатный образец Цифровой крепости на своем сайте в Интернете.

Этот прибор он купил в магазине электроники, оплатив покупку наличными, чтобы сохранить анонимность. Никто лучше его не знал, как тщательно следило агентство за своими сотрудниками, поэтому сообщения, приходящие на этот пейджер, как и отправляемые с него, Стратмор старательно оберегал от чужих глаз. Сьюзан опасливо огляделась.

In the literature, the concept of a low duty cycle is represented as a periodic wake​-up scheme. A node wakes up periodically to transmit or receive packets from.

Wireless sensor network WSN refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location.

an essential component of any communication protocols, especially routing proto​- cols. miliar concept to the wireless communications and network research community, it typically will consider random duty-cycling where sensor nodes are on/awake with a certain adopted for simplicity in presentation in our analysis.
