Absrrad-Key challenges in wireless mobile ad hoc networks are computational resource constraints, power limitatious, and efficient service discovery techniques. The short range radio network fechnology Bluetooth suffers from long service discovery delays and high power consumption due to necessary connection establishment between discovering and discovered entity. For improving the efficiency of service discovery in Bluetwth networks we propose two new approdches. By leveraging the implicit broadcast capability of the Bluetooth inquiry procedure, we significantly reduce the service discovery time and hence lower the power consumption. Moreover, we enable the integration of resource limited devices which are incapable of taking part in service discovery themselves. Based on a performance evaluation and a comparison with the legacy Bluetooth Service Discovery Protocol (SDP), we present the benefits of our new approaches.
Pervasive computing requires management techniques allowing efficient service handling in volatile contexts. The Java Enhanced Service Architecture (JESA) is a service platform addressing this issue for resource limited devices. A major problem in dynamic service networks is the discovery of desired services. The JESA Service Discovery Protocol (JSDP), one of JESA's core components, is a lightweight, platform independent service discovery protocol for ad-hoc networks. JSDP features transparent operation with or without central service brokers providing scalability from point-to-point connections to larger structured networks.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
