“…Groba and Clarke identified the impact of topology changes in a service communication; in order to reduce the service failure, a composition protocol is designed, and it is able to allocate and minimize the service invoked at the providers' end. Moreover, it is able to choose appropriate services opportunistically at the time of the service requisition process.…”

The wireless networking technology era has entered into a new fame through the use of body sensors and their pervasive device communication. Body sensors are one among the widely used technologies that outperforms without human intervention. The body sensors and wireless communication technology coordinate with each other to complete the assigned task. In a patient monitoring system, due to insufficiency of resources, there might be a delay in transmitting sensitive data in case of emergency, which leads to a critical problem. Ad hoc sensor networks have n number of sensors deployed in a geographical pasture. The communication capabilities of deployed sensors have limited intelligence technology for processing the absorbed data via network. Few areas identified for envisioning sensors to fame a wireless sensor ad hoc networks include: (1) military sensor networks to monitor enemy movements and explosions inside the protection zone; (2) monitoring the explosion caused in industrial areas because of chemical, biological, radiological, and nuclear plants, and so on, and in these areas, a sensor networks might be deployed to detect and help to avoid the disasters; (3) natural debacle monitoring for recognizing that environmental changes turn out differently at different geographical limits; (4) city traffic monitoring to handle congested roads and vehicles during emergency and peak hours; (5) security surveillance sensors to avoid malpractices in crowded bazaars, shopping malls, festival areas, and so on; (6) patient monitoring is also a part of the wireless sensor network and might be integrated with body sensors to process the patient's medical data, collected from their daily activities. These suggested areas have their own network enhancements as they have operational efficiency and applicability among different regions. From each and every sensor, data collected from their deployed area should have the ability to aggregate the addressable data, which are generated at particular periods of time. The major aim of a wireless ad hoc sensor network is to disseminate the collected information at the right time to the corresponding base-reporting station. Areas like healthcare monitoring, defense sector, security surveillance, natural disaster monitoring, automated machine monitoring and so on are particularly highly sensitive, and the communication should be reported immediately for instant execution.The mobility of bring your own devices (BYODs) might vary from time to time and region to region. In Figure 1, sample sensors are observed to be deployed in a region and communicate through assigned gateway, and they report to the base station via devices assigned to do that particular task. Cordless sensors have a huge drawback, their lifetime, due to its energy limitation. They should maintain their energy limit as maximum as they can, but to react in emergency cases, they must utilize the energy with a minimum precautionary expenditure. Potentially, there should be highly reconfigurable and self-organized sensor networ...

“…3 adopts a heuristic procedure that tries to determine a "good enough" composition, without a strict guarantee that an optimal solution will be found. The procedure is based on a greedy approach similar to the ones proposed in [9,19], which resolves services in Σ W on a stepby-step basis, starting from the initial node of W : indeed, a required service σ is bound to a matching concrete service only if all preceding services in Pred (σ) have already been resolved (line 7). The rationale for this mechanism is that only when Pred (σ) is fully resolved, it is possible to know the worst case increment to the path length caused by resources in the set of known candidates for σ, and to select the one causing the minimal increment (lines 7-9).…”

“…Groba and Clarke [9] propose a service composition protocol that invokes service providers in ad hoc networks with the goal of minimizing the impact of topology changes and reducing failures. The proposed approach supports parallel service flows, but presents some limits with respect to composite complexity, network density, and service demand.…”

“…Rather, they motivate the need of decentralized and self-adaptive approaches to achieve an adequate degree of robustness, resiliency and scalability. Approaches of this kind have already been proposed [9,19], mostly based on the assumption of a decentralized orchestration of the application workflow, using structured or unstructured P2P network architectures.…”

Abstract. Dynamic service composition represents a key feature for service-based applications operating in dynamic and large scale network environments, as it allows leveraging the variety of offered services, and to cope with their volatility. However, the high number of services and the lack of central control pose a significant challenge for the scalability and effectiveness of the composition process. We address this problem by proposing a fully decentralized approach to service composition, based on the use of a gossip protocol to support information dissemination and decision making. The proposed system builds and maintains a composition of services that fulfills both functional and non functional requirements. For the latter, we focus in particular on requirements concerning the composite service completion time, taking into account both the response time and the impact of network latency. Simulation experiments show that our solution converges quickly to a feasible composition and can self-adapt to dynamic changes concerning both service availability and network latency.
