A Secure Service-Oriented Routing Algorithm for Heterogeneous Wireless Mesh Networks

For future wireless networks, a major challenge is how to efficiently support applications and services to end-users. Currently, most existing solutions attempt to address this issue on the application layer. In this paper, we take a different approach and we present a unified routing algorithm to efficiently enable applications in a Heterogeneous Wireless Mesh Network (HWMN). The algorithm builds upon service-oriented architecture (SOA) concepts, and more importantly, it provides confidential and reliable communication links over the mesh. Three techniques are implemented: key management, key shifting, and node relations. Such an approach provides a guideline to design secure and service-oriented HWMNs.
