Wireless mesh networks are emerging as a promising robust low-cost network architecture able to provide increased coverage and larger bandwidth, resulting in higher quality of service and information availability. Many distributed applications provided on wireless mesh networks enable collaborations and sharing of information. Such applications benefit from scalable, robust and secure group services such as one-to-many or many-to-many multicast and distributed data access. Group services, in turn, require support from infrastructure protocols such as routing, or security mechanisms such as authentication, access control and key management. The goal of this project is to advance state-of-the-art group-oriented services in the context of wireless mesh networks. The project presents new formulations of distributed problems capturing the particularities of wireless mesh networks and the interactions between security, availability and scalability. It also studies the viability and limitations of cross-layer design as a new paradigm of building secure network services. Innovative results consist of scalable one-to-many and many-to-many wireless multicast protocols that provide support for efficient group communication, scalable data sharing algorithms that are robust to malicious behavior, high-throughput, robust and secure routing that assist applications to achieve high-performance, scalable key management protocols and authentication mechanisms enabling decentralized infrastructure access services. This project contributes to the education of the next generation of secure systems designers, generating interactions between the distributed systems, security and wireless networks research areas.
