An Active Resource Orchestration Framework For Pan-Scale, Sensor-Rich Environments

ABSTRACT:

In this paper, we present Orchestrator, an active resource orchestration framework for a PAN-scale sensor-rich mobile

computing platform. Incorporating diverse sensing devices connected to a mobile phone, the platform will serve as a common base to accommodate personal context-aware applications. A major challenge for the platform is to simultaneously support concurrent applications requiring continuous and complex context processing, with highly scarce and dynamic resources. To address the challenge, we build Orchestrator, which actively coordinates applications’ resource uses over the distributed mobile and sensor devices. As a key approach, it adopts an active resource use orchestration, which prepares multiple alternative plans for application requests and selectively applies them according to resource availability and demands at runtime. Through the selection, it resolves resource contention among applications and helps them efficiently share resources. With such system-level supports, applications

become capable of providing long-running services under dynamic circumstances with scarce resources. Also, the platform can host a number of applications stably, exploiting its full resource capacity. We build an Orchestrator prototype on off-the-shelf mobile devices and sensor motes and show its effectiveness in terms of application supportability and resource use efficiency.

EXISTING SYSTEM:

This new environment raises an important challenge; the platform should run a number of concurrent applications with highly scarce and dynamic resources. Greedy resource use by an application would significantly aggravate contentions among multiple applications and deepen skewed uses of specific devices. This can lead to substantial reduction of overall system capacity.It is almost impossible for individual applications to address these challenges and ensure applications’ steady running.

DISADVANTAGES OF EXISTING SYSTEM:

v Without system-level supports, an application has an extremely limited view on the resource uses of other applications, and hardly negotiates with them for coordinated

resource use.

v Individual applications hardly adapt to the joins and leaves  

    of heterogeneous sensors, and the starts and stops of other

    applications.

PROPOSED SYSTEM:

      We propose Orchestrator, a novel active resource orchestration framework. Actively interplaying multiple context-aware applications and scarce, dynamic resources within a PAN, Orchestrator hosts concurrent applications stably, exploiting its full resource capacity. More specifically, it helps applications share in resources and processing with a holistic view on the applications and resources.

ADVANTAGES OF PROPOSED SYSTEM:

v It resolves resource contention among applications.

v It provides continuous context monitoring services, adapting to dynamic sensor membership and their resource availability.

v With such system supports, applications can provide mobile users with seamless and long-running services by delegating complex resource management details to the system.
