【摘要】:無(wú)線體域網(wǎng)(WBAN)屬于物聯(lián)網(wǎng)的概念,將人體與互聯(lián)網(wǎng)連接到一起。WBAN在遠(yuǎn)程醫(yī)療診斷、醫(yī)療監(jiān)護(hù)和生理參數(shù)測(cè)量等方面都發(fā)揮著至關(guān)重要的作用,可以實(shí)時(shí)的將人體的生理參數(shù)傳至手機(jī)或電腦等設(shè)備上,對(duì)人體的健康狀況做出正確的判斷,從而可以做到有效的預(yù)防和及時(shí)的治療。典型的WBAN最重要的設(shè)計(jì)和實(shí)施規(guī)則之一是可靠性。當(dāng)節(jié)點(diǎn)向匯聚節(jié)點(diǎn)發(fā)送數(shù)據(jù)包時(shí),由于環(huán)境的影響,節(jié)點(diǎn)之間的干擾,不穩(wěn)定鏈路或其他原因,節(jié)點(diǎn)可能在路由過(guò)程中丟失數(shù)據(jù)包。因此,本文將嘗試模擬人體的真實(shí)環(huán)境,對(duì)其可靠性做出研究。本文基于Castalia的仿真平臺(tái),構(gòu)建了WBAN的框架結(jié)構(gòu),采用了對(duì)數(shù)正態(tài)陰影衰落模型作為平均路徑損耗,采用了IEEE802.15.6數(shù)據(jù)傳輸協(xié)議,并調(diào)用了干擾模型以符合人體的真實(shí)環(huán)境,對(duì)安放于人體的傳感器節(jié)點(diǎn)的個(gè)數(shù)也做出調(diào)整,使其盡可能的包含當(dāng)前人體大部分的傳感器節(jié)點(diǎn),以使仿真的環(huán)境更加接近于人體環(huán)境。在此基礎(chǔ)之上,本文對(duì)植入的貪婪周長(zhǎng)無(wú)狀態(tài)路由與Castalia原有的多徑環(huán)形路由的性能進(jìn)行了仿真分析。本文的創(chuàng)新點(diǎn)在于:第一,對(duì)應(yīng)用層做出了調(diào)整,加入了定位的功能,可實(shí)時(shí)監(jiān)測(cè)節(jié)點(diǎn)的位置,并將拓?fù)浣Y(jié)構(gòu)設(shè)置為兩跳拓?fù)。第?加入了節(jié)點(diǎn)的移動(dòng)性,在無(wú)線信道中對(duì)節(jié)點(diǎn)的移動(dòng)性的路徑損耗進(jìn)行了建模,同時(shí)調(diào)用了移動(dòng)管理模塊下的線性移動(dòng)管理模塊,使網(wǎng)絡(luò)架構(gòu)更加符合體域網(wǎng)傳感器網(wǎng)絡(luò);第三,對(duì)貪婪周長(zhǎng)無(wú)狀態(tài)路由(GPSR)和多徑環(huán)形路由(MultipathRingsRouting)兩種路由協(xié)議的性能進(jìn)行了仿真。首先,分別分析了兩種路由協(xié)議下,不同節(jié)點(diǎn)數(shù)目、不同速率下的包的吞吐量、時(shí)延、丟包率,之后對(duì)比分析了基于GPSR和Multipath Ring Routing兩種路由協(xié)議下無(wú)線體域網(wǎng)的吞吐量、包延遲、包接收情況,為GPSR和MultipathRing Routing兩種路由協(xié)議應(yīng)用到無(wú)線體域網(wǎng)上提供了一定的理論依據(jù)和參考價(jià)值。
[Abstract]:Wireless body area network (WBAN) belongs to the concept of the Internet of things, which connects the human body with the Internet. WBAN plays an important role in telemedicine diagnosis, medical monitoring and physiological parameter measurement. The physiological parameters of the human body can be transmitted to the mobile phone or computer in real time to make a correct judgment on the health status of the human body, so that effective prevention and timely treatment can be achieved. One of the most important design and implementation rules of a typical WBAN is reliability. When a node sends a packet to a sink node, due to the influence of the environment, the interference between nodes, unstable links or other reasons, the node may lose the packet during the routing process. Therefore, this paper will try to simulate the real environment of human body and study its reliability. In this paper, based on the simulation platform of Castalia, the frame structure of WBAN is constructed. The logarithmic normal shadow fading model is used as the average path loss, and the IEEE802.15.6 data transmission protocol is adopted, and the interference model is called to fit the real environment of human body. The number of sensor nodes placed in the human body is also adjusted to make it contain as many sensor nodes as possible, so that the simulated environment is closer to the human environment. On this basis, the performance of the embedded greedy perimeter stateless routing and the original multipath ring routing of Castalia are simulated and analyzed in this paper. The innovations of this paper are as follows: first, the application layer is adjusted, the location function is added, the node position can be monitored in real time, and the topology structure is set to two-hop topology. Secondly, the mobility of nodes is added, and the path loss of the mobility of nodes is modeled in the wireless channel, and the linear mobile management module under the mobile management module is called to make the network architecture more in line with the sensor network of the body area network. Thirdly, the performance of greedy cycle stateless routing (GPSR) and multipath ring routing (MultipathRingsRouting) are simulated. First of all, the throughput, delay and packet loss rate of two routing protocols, different nodes and different rates, are analyzed respectively. Then, the throughput and packet delay of wireless body area network based on GPSR and Multipath Ring Routing routing protocols are compared and analyzed. Packet reception provides a theoretical basis and reference value for the application of GPSR and MultipathRing Routing routing protocols to wireless body area networks.
