Recent technological advancements in miniaturization of sensor and wireless communication lead to development of Wireless Body Area Networks (WBAN). It is similar to Wireless Sensor Networks but mainly focuses on health care applications to monitor the health condition of patient continuously. It consists of implantable and wearable computing devices placed inside or outside the surface of human body for sensing and data communication. Due to continuous operation, the sensor node introduces electromagnetic radiations which causes damage to delicate human tissues as well as degrades the performance of the network. In addition, WBAN data are sensitive to delay and it is necessary to send critical patient data to the remote server in a timely manner to protect patient’s life. However, alternating the routing path of critical data leads to collision, packet loss, high power consumption, maximum delay and reduced network life time. In this paper, Optimum Path Optimum Temperature Routing Protocol is introduced to address the above issues. The proposed protocol chooses optimum routing path by determining the temperature of sensor nodes and by defining two threshold limits (minimum and maximum). It also considers the critical data signals to be sent when the temperature of node exceeds the admissible threshold limit. The obtained simulation results are compared with conventional routing protocols and was analyzed that the proposed protocol has decreased delay, minimum energy, reduced power, uniform temperature distribution and maximum lifetime of sensor node.

WBAN的自热控制节能OPOT路由协议

传感器和无线通信的小型化方面的最新技术进步导致了无线人体局域网(WBAN)的发展。它类似于无线传感器网络,但主要侧重于医疗保健应用程序以连续监视患者的健康状况。它由放置在人体表面内部或外部的可植入和可穿戴计算设备组成,用于传感和数据通信。由于连续操作,传感器节点会引入电磁辐射,这会对脆弱的人体组织造成损害,并降低网络的性能。另外,WBAN数据对延迟很敏感,因此有必要将关键的患者数据及时发送到远程服务器以保护患者的生命。但是,交替更改关键数据的路由路径会导致冲突,丢包,高功耗,最大延迟和缩短的网络寿命。在本文中,引入了最佳路径最佳温度路由协议来解决上述问题。所提出的协议通过确定传感器节点的温度并定义两个阈值限制(最小和最大)来选择最佳路由路径。当节点的温度超过允许的阈值限制时,它也考虑发送关键数据信号。将获得的仿真结果与常规路由协议进行比较,并分析该协议具有减少的延迟,最小的能量,降低的功率,均匀的温度分布和最大的传感器节点寿命。最佳路径最佳温度路由协议被引入以解决上述问题。所提出的协议通过确定传感器节点的温度并定义两个阈值限制(最小和最大)来选择最佳路由路径。当节点的温度超过允许的阈值限制时,它也考虑发送关键数据信号。将获得的仿真结果与常规路由协议进行了比较,并分析了所提出的协议具有减少的延迟,最小的能量,降低的功率,均匀的温度分布和最大的传感器节点寿命。最佳路径最佳温度路由协议被引入以解决上述问题。所提出的协议通过确定传感器节点的温度并定义两个阈值限制(最小和最大)来选择最佳路由路径。当节点的温度超过允许的阈值限制时,它也考虑发送关键数据信号。将获得的仿真结果与常规路由协议进行了比较,并分析了所提出的协议具有减少的延迟,最小的能量,降低的功率,均匀的温度分布和最大的传感器节点寿命。当节点的温度超过允许的阈值限制时,它也考虑发送关键数据信号。将获得的仿真结果与常规路由协议进行比较,并分析该协议具有减少的延迟,最小的能量,降低的功率,均匀的温度分布和最大的传感器节点寿命。当节点的温度超过允许的阈值限制时,它也考虑发送关键数据信号。将获得的仿真结果与常规路由协议进行了比较,并分析了所提出的协议具有减少的延迟,最小的能量,降低的功率,均匀的温度分布和最大的传感器节点寿命。
