摘要:

本文提出了一种新的异构无线体域传感器网络路由协议:支持移动性的基于自适应控制的热感知节能多跳协议(M-ATTEMPT)。定义了一个将异构传感器应用于人体的原型。直接通信用于实时流量(关键数据)或按需数据,而多跳通信用于正常数据传输。WBASN中的主要挑战之一是感测由植入的传感器节点产生的热量。所提出的路由算法是热感知的,其感测链路热点并将数据路由远离这些链路。人体的持续移动导致先前建立的链接之间的断开。因此,移动性支持和能量管理的引入,以克服这个问题。提出了一种最大信息抽取和最小能耗的线性规划模型。MATLAB仿真所提出的路由算法进行了生命周期和成功的数据包交付相比,多跳通信。实验结果表明,与多跳通信相比,该路由算法具有更低的能耗和更高的可靠性。

英文摘要:

In this paper, we propose a new routing protocol for heterogeneous Wireless Body Area Sensor Networks (WBASNs); Mobility-supporting Adaptive Threshold-based Thermal-aware Energy-efficientMulti-hop ProTocol (M-ATTEMPT). A prototype is defined for employing heterogeneous sensors on human body. Direct communication is used for real-time traffic (critical data) or on-demand data while Multi-hop communication is used for normal data delivery. One of the prime challenges in WBASNs is sensing of the heat generated by the implanted sensor nodes. The proposed routing algorithm is thermal-aware which senses the link Hot-spot and routes the data away from these links. Continuous mobility of human body causes disconnection between previous established links. So, mobility support and energy-management is introduced to overcome the problem. Linear Programming (LP) model for maximum information extraction and minimum energy consumption is presented in this study. MATLAB simulations of proposed routing algorithm are performed for lifetime and successful packet delivery in comparison with Multi-hop communication. The results show that the proposed routing algorithm has less energy consumption and more reliable as compared to Multi-hop communication.
