“…At first, an instance of the desired Web service must be found and passed to the WSDL-finder. Discovery of Web services in dynamic and transient networks can be achieved with methods as presented in [12,21]. However, this is not a task of the tool and must be done by the client.…”

“…In [12] we introduced a system consisting of a combination of dynamic Web service discovery based on distributed UDDI [15] registries, and of a Web service replicator mechanism for ad-hoc networks, which was work in early progress at that time. Since then, the replicator evolved towards being more scalable, flexible, and bandwidth-saving, and, therefore, better suited for mobile ad-hoc networks.…”

“…In [12] we presented a system for dynamic discovery and replication of Web services in ad-hoc networks, for utilizing the publish-find-bind paradigm of SOAs even in typically unreliable network environments. The contribution of the current paper is concerned with the evolution of the replication mechanism and the results of a case study, simulating the system's behavior in largescale ad-hoc environments, in order to find optimal trade-offs for an effective replication.…”

Web services are gaining high popularity and importance on mobile devices. Connected to ad-hoc networks, they provide the possibility to establish spontaneously even complex service-based workflows and architectures. However, usually these architectures are only as stable and reliable as the underlying network infrastructure. Since topologies of mobile ad-hoc networks behave unpredictably, dependability within them can be only achieved with a dynamic replication mechanism. In this paper we present a highly flexible solution for replication and synchronization of stateful Web services and discuss the behavior of the implemented prototype in large-scale simulations.

“…In [2], [3], the replication process depends on the whole knowledge of the network where nodes should require the information about the other nodes in the network. By using link quality to predict network partitioning, the original service is replicated to the node with high battery lifetime in the partition.…”

“…There have been proposed several methods that replicate a service to some new host nodes based on particular strategies such as a whole knowledge of the network [2], [3], network partitioning [4]- [8], network density [9], or client's request rate [10]. Most of these methods focus on how to increase the service availability without taking into account the energy consumption.…”

SUMMARYMobile Ad Hoc Networks (MANETs) offer quick and easy network deployment in situations where it is not possible otherwise and they can be used to provide mobile users with a temporary infrastructure to use services in the absence of fixed infrastructure. Nodes in MANETs are free to move and organize themselves in an arbitrary fashion. The challenging task in such dynamic environments is how to improve the service availability. Replicating a service at some nodes distributed across the network is an effective strategy. However, service replication can considerably impact the system energy consumption. Since mobile devices have limited battery resources, a dynamic and efficient service replication is necessary to support such environments. In this paper, we propose a distributed service replication scheme for achieving high service availability with reasonable energy consumption for MANETs. The proposed method called HDAR (Highly Distributed Adaptive Service Replication) divides the whole network into disjoint zones of at most 2-hops in diameter and builds a dynamic replication mechanism which selects new replica zones depending on their service demand and the tradeoff between the communication and replication energy consumption costs. Through simulations, we confirmed that our approach can achieve higher service availability with reasonable energy consumption than existing methods.

Achieving high-availability in service-oriented systems is a challenge due to the distributed nature of the architecture. Redundancy, using replicated services, is a common software strategy for improving the availability of services. However, traditional replication strategies are not appropriate for service-oriented systems, where diverse services may be grouped together to provide redundancy. In this paper we describe the requirements for a redundancy protocol and propose a set of processes to manage redundant service providers.
