Abstract
The synergy of computational and physical network components leading to the Internet of Things, Data and Services has been made feasible by the use of Cyber Physical Systems (CPSs). CPS engineering promises to impact system condition monitoring for a diverse range of fields from healthcare, manufacturing, and transportation to aerospace and warfare. CPS for environment monitoring applications completely transforms human-to-human, human-to-machine and machine-to-machine interactions with the use of Internet Cloud. A recent trend is to gain assistance from mergers between virtual networking and physical actuation to reliably perform all conventional and complex sensing and communication tasks. Oil and gas pipeline monitoring provides a novel example of the benefits of CPS, providing a reliable remote monitoring platform to leverage environment, strategic and economic benefits. In this paper, we evaluate the applications and technical requirements for seamlessly integrating CPS with sensor network plane from a reliability perspective and review the strategies for communicating information between remote monitoring sites and the widely deployed sensor nodes. Related challenges and issues in network architecture design and relevant protocols are also provided with classification. This is supported by a case study on implementing reliable monitoring of oil and gas pipeline installations. Network parameters like node-discovery, node-mobility, data security, link connectivity, data aggregation, information knowledge discovery and quality of service provisioning have been reviewed.

A complete transformation of human-to-human, human-to-machine and machine-to-machine interactions is expected with the introduction of virtualization [90]
Summary
Technological advancement in semiconductor design, material sciences and networking are driving the ubiquitous deployment of large scale wireless sensor and actuator networks [1]. These technologies have merged to enable Wireless Sensor Networks (WSNs) that can provide low-cost, low power, multifunctional miniature devices with interfaces to connect with a multitude of sensors [2] These devices can gather sensed information from the environment and communicate it in an untethered manner over a short distance that can be further routed by means of multi-hop to a central monitoring station. Cyber Physical Systems (CPS) principles are finding their way into sensing applications as a platform to provide extended interactive functionality between real time and virtual environments. Resource constraints include limited bandwidth, limited amount of energy, limited processing power, low storage capacity, and short communication range Such constraints are in general not coupled with other wireless and cellular networks [10,11]; WSN require special deployment consideration from coverage perspective as well.
