DTMP: Energy Consumption Reduction in Body Area Networks Using a Dynamic Traffic Management Protocol
Advances in medical sciences with other fields of science and technology is closely casual profound mutations in different branches of science and methods for providing medical services affect the lives of its descriptor. Wireless Body Area Network (WBAN) represents such a leap. Those networks excite new branches in the world of telemedicine. Small wireless sensors, to be quite precise and calc...
A Wireless Sensor Network (WSN) is a wireless network consisting of spatially distributed autonomous tiny computing devices, each equipped with sensors, a wireless radio, a processor, and a power source. Sensor networks are envisioned to be deployed in the physical environment in order to monitor a wide range of environmental phenomena. Efficient usage of energy is one of the most important con...
افزایش روز افزون تقاضا برای شبکه های حسگر بی سیم(wireless sensor networks)، به دلیل نداشتن هزینه و محدودیت های سیم کشی موجود در شبکه های کابلی، ارزان بودن حسگرها و نیز قابل استفاده برای کاربردهای خاص با کمترین مداخله انسان در حین کار شبکه باعث شده تا wsn مورد توجه خاصی قرار بگیرد. امروزه استفاده از شبکه های سنسور بیسیم در کاربردهای پزشکی رشد زیادی داشته است. به دلیل رشد تکنولوژی سنسورها در این ...
