Testbed performance analysis of cross-layer based service discovery in Wireless Mesh Networks

In this paper we investigate and evaluate two cross-layer based service discovery protocols for wireless mesh networks. For both protocols we provide a testbed implementation and analyze the feasibility for real world usage. For the class of proactive protocols we encapsulate DNS based service discovery messages in a new message type for the optimized link state routing (OLSR) protocol. For the class of reactive protocols we introduce new message types for the dynamic MANET on demand routing (DYMO) protocol which discovers service and corresponding route in one message. As our results from a testbed show, some modifications have to be made before those protocols are really usable. With our results we deliver optimizations which make those protocols efficient under real conditions.
