سیستم مانیتورینگ بیمار با استفاده از اینترنت اشیا Patient monitoring system using IoT

I. INTRODUCTION: Internet of Things (IOT) is advanced area which includes embedded technology, wireless sensor network, artificial intelligence and machine learning etc. to intercommunicate things. IOT improves user convenience and also enhances data collection. It optimizes various technologies in single area called IOT. IOT has applications across different fields like industries, engineering and medical. To improve existing medical systems IOT is applicable. In medical IOT, Wireless Body Area Network (WBAN) is key concept which is network of autonomous medical sensors which are deployed inside or outside of the patient body for health monitoring. In WBAN, deployed wearable sensors senses health conditions like pulse rate, heart beats, blood pressure, temperature etc. using IOT exploited devices. Data from multiple sensor nodes is collected to sink called data fusion and it is transmitted to analyser. In wireless sensor networks, data is passes through communication from one end to another end. Information can be travel hop by hop or multihop manner in the sensor network [5]. But for reliable data delivery over the network, faster data transmission is necessary during communication. So, different types of routing protocols are used by researchers. Routing protocols are helps to search minimum distance path between sources and sink node [6] [7]. Energy efficiency is important factor in wireless sensor networks. Heavily congested network will be consuming more energy in the network. So, different MAC and routing protocols are used for to increase the energy efficiency of the node [8]. Some hybrid protocols also designed for reduce power consumption by the nodes. Clustering technique is a better solution for achieve energy efficiency over the network communication [9] [10]. Energy parameter effected due to the collision of packets during packets travel from one node another node. In case of large application, multiple nodes can send packet at a same time to the receiver end [11] [12]. So collision event will be generating near the receiver end. Hybrid MAC protocols are designed and developed for solve congestion and collision problem in wireless sensor networks [13][14]. Routing as well as MAC protocols are necessary for reliable data delivery in the network.[15] In case of intermediate node failure, routing protocols should be select alternative path for packets delivery over the network [16] [17].
