MAC layer security issues in wireless mesh networks. Wireless Mesh Networks WMNs have emerged as a promising technology for a broad range of applications due to their self-organizing, self-configuring and self-healing capability, in addition to their low cost and easy maintenance.
Securing WMNs is more challenging and complex issue due to their inherent characteristics such as shared wireless medium, multi-hop and inter-network communication, highly dynamic network topology and decentralized architecture.
The existing MAC layer standards and implementations are inadequate to secure these features and fail to provide comprehensive security solutions to protect both backbone and client mesh. Hence, there is a need for developing efficient, scalable and integrated security solutions for WMNs. In this paper, we classify the MAC layer attacks and analyze the existing countermeasures.
Based on attacks classification and countermeasures analysis, we derive the research directions to enhance the MAC layer security for WMNs. Ethernet passive optical network EPON , which represents the convergence of low-cost, high-bandwidth and supporting multiple services, appears to be one of the best candidates for the next-generation access network. The final release is expected in To implement those functions mentioned above, an embedded real-time operating system RTOS and a flexible programmable logic device PLD with an embedded processor are used.
The software and hardware functions in MAC layer are realized through programming embedded microprocessor and field programmable gate array FPGA. Finally, some experimental results are given in this paper. Modeling MAC layer for powerline communications networks.
