    This study addresses the critical challenge of mobility management in Wireless Mesh Networks (WMNs), focusing on the performance comparison of various Mobility Management Protocols (MMPs). The diverse range of MMPs, including Proxy Mobile IPv6 (PMIPv6), Fast PMIPv6 (FPMIPv6), Mobile IPv6 (MIPv6), Hierarchical MIPv6 (HMIPv6), Fast MIPv6 (FMIPv6), and Fast Hierarchical MIPv6 (FHMIPv6), present distinct advantages and limitations in terms of performance, scalability, security, and flexibility. Selecting the most suitable MMP for a given WMN application is a complex task, primarily due to the lack of comprehensive evaluation metrics that accurately reflect network efficiency. Furthermore, quantitative performance comparisons among these protocols are notably scarcen in existing research. Therefore, this research aims to contribute by categorizing MMPs applicable in Inter network WMN environments, developing a simulated WMN environment using the Network Simulator (NS-2), and conducting a thorough performance evaluation of various MMPs. Based on the result, the PMIPv6 outperform and able to provide 99.99% in packet delivery ratio, highest throughput compares to other MMPs. The outcomes of this study are expected to provide valuable insights for guiding the selection of MMPs based on specific application requirements, thereby contributing to the advancement of efficient and reliable WMN deployments

    It is expected that the footprint of the Internet of Things (IoT) will increase in the future. In order for this increase to occur, a network architecture which is flexible and capable of handling multiple flows with varying requirements as well as dynamically meeting the current demands. A new era of dynamic entities (nodes) within an environment like smart hospitals and cities is being empowered by IoT. The Sensor Proxy Mobile IPv6 (SPMIPv6) has been specifically determined for IP-based wireless sensor network (WSN) mobility with the aim of potentially reducing the consumption of energy by means of preserving the mobile nodes from being part of the handoff process. The majority of the shortcomings of the Proxy Mobile IPv6 (PMIPv6) such as non-optimized communication path, long handoff latency, and bottleneck issues were inherited by SPMIPV6. An improved SPMIPv6 architecture called Distributed SPMIPv6 (DSPMIPv6) is presented in this work with the aim of addressing the aforementioned problems. The solution proffered in the present architecture includes de-coupling the entities that are part of the control and data planes; the Dynamic Mobility Access Gateway (MAG) located close to the edge of the network distributes and manages the data plane, while the control plane, is dependent on a central entity called Sensor Local Mobility Anchor (SLMA). The introduced design is evaluated analytically, and the numerical results show that the performance of the DSPMIPv6 design is better than that of both SPMIPv6 and PMIPv6 protocols in terms of Local Mobility Anchor (LMA) load, and transmission cost performance metrics.
