Transmission Delay of Multi-hop Heterogeneous Networks for Medical Applications

Abstract

Nowadays, with increase in ageing population, Health care market keeps growing. There is a need for monitoring of Health issues. Body Area Network consists of wireless sensors attached on or inside human body for monitoring vital Health related problems e.g, Electro Cardiogram (ECG), ElectroEncephalogram (EEG), ElectronyStagmography(ENG) etc. Data is recorded by sensors and is sent towards Health care center. Due to life threatening situations, timely sending of data is essential.For data to reach Health care center, there must be a proper way of sending data through reliable connection and with minimum delay. In this paper transmission delay of different paths, through which data is sent from sensor to Health care center over heterogeneous multi-hop wireless channel is analyzed. Data of medical related diseases is sent through three different paths. In all three paths, data from sensors first reaches ZigBee, which is the common link in all three paths. After ZigBee there are three available networks, through which data is sent. Wireless Local Area Network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunication System (UMTS) are connected with ZigBee. Each network (WLAN, WiMAX, UMTS) is setup according to environmental conditions, suitability of device and availability of structure for that device. Data from these networks is sent to IP-Cloud, which is further connected to Health care center. Main aim of this paper is to calculate delay of each link in each path over multihop wireless channel.

An advanced heterogeneity-aware centralized energy efficient clustering routing protocol for wireless sensor networks

“…These multiple units are attached to the power units of individual sensors resulting in a much higher energy dissipation. Therefore, limited energy resources that are available at a sensor node should be utilized efficiently [12], [13].…”

面向工业监控应用的广域异构无线网络端到端时延分析

“…并且面向实时性应用对该协议 的性能进行了理论分析. 文献 [20] 提出了用于医疗中的人体多跳异构网络, 对其端到端时延进行了分 析, 但是其网络模式包括 WLAN, WiMAX, UMTS 和 ZigBee 四种形式, 不适用于工业应用领域. 在 WIA-PA 的时延分析方面, 文献 [21] 分析了可预期周期性数据和不可预期数据在不同场景下 的时延.…”
