The potential for operating more mobile and dynamic networking infrastructures is raising new challenges in developing effective service registration and discovery technologies. Discovering and maintaining services within dynamic wireless networks is a challenge requiring novel mechanisms for more effective service detection, tracking, and adaptation. We discuss early prototyping of a service discovery framework based upon the service location protocol SLP called extended SLP xSLP. xSLP has been applied within mobile ad hoc network MANET environments to investigate design tradeoffs in both service discovery and registration. Simulations have been performed to examine three multicast routing algorithms and unicast routing in combination with xSLP. A fundamental challenge is operating with varying bandwidth, topological dynamics, errored links, and dynamic failure events. A fundamental goal of the work is to design more effective service discovery mechanisms for use in these types of challenged wireless network environments and to understand the protocol interactions at the routing and reliable transport layer.
