Improved Route Construction Protocol for Mobile Wireless Sensor Networks

Mobile wireless sensor networks (MWSNs) are a new development of static wireless sensor networks that allow the mobility of sensor nodes. Mobile sensor nodes are fundamental components of MWSNs. Because of this mobility of sensor nodes, the link between sensor nodes frequently changes, and packet loss occurs. Despite the packet loss of MWSNs, they also face challenges in energy consumption, communication overhead, and others. This research aims to analyze the performance of the hierarchical routing graph construction (HRGC) routing scheme. Its working mechanism and network structure suit all real-time applications with involved mobility. We discuss the limitations of the HRGC scheme theoretically and propose an improved routing scheme for data transmission in MWSNs based on HRGC. It should overcome the main limitations of HRGC, such as high data communication overhead, high energy consumption during network maintenance, data transmission process, and route failure issues due to mobility.
