Description

CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY



[0001] The present application claims priority from Indian patent application no. 201821034028, filed on September 10, 2018. The entire contents of the aforementioned application are incorporated herein by reference.

TECHNICAL FIELD



[0002] The disclosure herein generally relates to Internet of Things, and, more particularly, to system and method for enabling intelligent network services by cognitive sense-analyze-decide-respond framework.

BACKGROUND



[0003] In an Industry 4.0 scenario, there are many applications involving various Internet of Things (IoT) devices such as sensors, gateways, robots, Automated Guided Vehicles (AGVs), drones, etc. These applications demand high throughput, low latency and high reliability. Understanding the need of the applications and translating them to the network parameters and the protocol parameters is a major challenge. The IoT devices used here are many in number, often use different networking/communication technologies such as Wi-Fi (Wireless Fidelity), Bluetooth, LTE (Long Term Evolution), LAA (Licensed Assisted Access), etc., and generate moderate to huge amount of data traffic which needs to be communicated to a central node or the cloud for processing. Providing a reliable, stable, cost-effective and easy to manage network solution based on the demand of these applications, availability of the devices and networks and capability of the protocols deployed, remains a major challenge.

[0004] Dynamic optimal decision making to ensure high Quality of Experience (QoE) to the applications with the constraints of the network is a key challenge. In such scenarios, decision rules depend upon multiple parameters (application, network, link, energy, protocol, etc.) and hence a straight away decision is not possible. Apart from this, responding to the changes of the network/application/protocol, etc., at the right time with the appropriate framework becomes crucial. Moreover the framework should also be agnostic to the applications, devices, protocols and networking technology. The existing solutions today mostly either managing devices or the applications or the technology independently, i.e., in SILOs.

[0035] FIG. 4 is a block diagram illustrates an exemplary deployment model of the SADR framework, according to embodiments of the present disclosure. In an embodiment, each module (Sense, Analyze, Decide and Respond) includes a set of services. For example, one or more services can run independently in any computer (or computer systems), wherein the analyze and the decide services need not require any kind of interface support with the deployed network, whereas the sense and the respond services require appropriate interface support (Application Programming Interfaces (APIs) for sensing and respond) for normal operations. In an embodiment, these can be also handled with the SDNized approach in some cases. In an embodiment, one or more services run through a direct supervision of a central controller or a cognitive controller.

[0036] FIG. 5 illustrates a conventional non-SADR experimental setup with two Access Points (API and AP2), one sender device (mobile phone) and one Receiver device (workstation). A sender sends a video using regular HyperText Transfer Protocol (HTTP) streaming to the receiver. While sending, the sender moves from one place to other resulting in change in RSSI values received from access points and subsequently handoff from AP1 to AP2. The handoff can be triggered by the sender using the conventional mechanism.

[0037] FIG. 6 illustrates an experimental setup of the SADR framework based networking in accordance with embodiments of the present disclosure. For example, consider a simple experiment with two Access Points (API and AP2), one sender device (mobile phone) and one Receiver device (workstation). A sender sends a video using regular HyperText Transfer Protocol (HTTP) streaming to the receiver. While sending, the sender moves from one place to other resulting in change in the RSSI values received from the access points and subsequently handoff from AP1 to AP2. The handoff can be triggered by the cognitive controller - brain with the support of the SADR (Sense, Analyze, Decide and Respond) services and the SDN controller, resulting in smooth handoff.

[0038] FIG. 7 is a graphical representation that illustrates the experimental results by the conventional experimental setup with significant delay and packet drop before handoff.

[0039] FIG. 8 is a graphical representation that illustrates the experimental results by deploying the SADR framework according to embodiments of the present disclosure. For example, an effect of smooth handoff is shown. The SADR framework ensures less jitter and packet drops, and seamless handoff.

The method includes one or more following steps i.e., at step 902, at least one application parameter and at least one network parameter is sensed to obtain a plurality of sensed information. At step 904, the plurality of sensed information is analyzed being filtered and synchronized to generate a plurality of derived parameters. At step 906, a plurality of rules is determined based on the plurality of derived parameters. At step 908, the plurality of rules for a plurality of scenarios is validated to obtain a plurality of decisions. At step 910, at least one of (i) a network, (ii) an application and (iii) a protocol control is enabled based on the plurality of decisions. The plurality of sensed information is a multi-time scaled data set obtained for a plurality of use cases. The plurality of decisions correspond to a real-time decision or an off-line decision.

[0041] In an embodiment, the at least one application parameter may correspond to at least one of: (i) one or more Quality of Service (QOS) parameters, and (ii) one or more Key Performance Index (KPI) parameters.
