Mobile ad-hoc networks differ from fixed networks in two essential points: On one hand, the spontaneous formation of these networks by mobile devices requires a dynamic service management system that allows the users to discover and access services offered by other devices on-demand. On the other, multi-hop wireless communication leads to limited and heterogeneous quality-of-service properties of the corresponding transmission paths. Therefore, we developed and implemented a service management system based on the service location protocol SLP, which comprises an optimized caching strategy for dynamic service information and on-demand measurement modules for available bandwidth and connection stability. |
