Real Time Application

The sensor cloud is a combination of cloud computing with a wireless sensor network (WSN) which provides an easy to scale and efficient computing infrastructure for real-time application. A sensor cloud should be energy efficient as the life of the battery in the sensor is limited and there is a huge consumption of energy in the data centre in running the servers to provide storage. In this paper, we have classified energy-efficient techniques for sensor cloud into different categories and analyzed each technology by using various parameters. Usage percentage of each parameter for every technology is calculated and for all technologies on average is also calculated. From our analysis, we found that most of the energy-efficient techniques ignore quality of service (QoS) parameters, scalability, and network lifetime. Multiparameter optimization including other QoS parameters along with energy may be the future direction of research. Our study will be helpful for researchers to get information regarding current methods used for an energy-efficient sensor cloud and also to build advanced systems in the future.

This chapter examines requirements elicitation for complex systems from a theoretical and practical perspective. System stakeholders, requirements sources, and the quality of requirements are presented with respect to the process, including an investigation into the roles of requirements engineers during elicitation. The main focus of the chapter is a review of existing requirements elicitation techniques and a survey of current trends and challenges. It is concluded with some views on the future direction of requirements elicitation in terms of research, practice and education. It is the intention of the authors that readers of this chapter will be sufficiently informed on the concepts, techniques, trends, and challenges of requirements elicitation to then apply this knowledge to system development projects in both industrial and academic environments.

Wireless Sensor Network (WSN) is a collection of battery operated sensors deployed in the monitoring area. A massive quantity of energy of the nodes is used in the internal and external communications. There is a need of energy saving mechanism for effective and efficient communication. In this paper, we propose a new Modified-LEACH (MD-LEACH) protocol for enhancing the Quality of Services (QoS) parameters. This hierarchical routing protocol (MD-LEACH) is inspired by the k-means clustering technique to consolidate sensor networks into clusters and acquire an enhanced QoS parameter. The kmeans algorithm efforts to improve the clustering procedure of LEACH protocol using Euclidean distance and prolong the lifespan of the sensor network. This algorithm forms the optimized clusters by a distance of cluster head from cluster nodes and energy of the nodes for designated the cluster heads. To evaluate the performance of the proposed approach, we used NS-2 simulator, and consider the QoS parameter, namely: packet delivery ratio, energy consumption, bandwidth, and throughput. The simulations results show that the MD-LEACH algorithm outperforms then the LEACH protocol by optimizing all QoS parameters and improved network performance.

The quality of hospitality education is a topical issue. It is being increasingly realised that the education level of tourism employees impacts on the quality of a country’s tourism industry. As the most tourism‐oriented region globally, the Caribbean is slowly awakening to the realisation that, unless its tourism employees are highly educated and skilled, the region will continue to account for an insignificant percentage of world tourism arrivals. In Grenada, hospitality education courses are limited, given the small tourism plant and comparatively low visitor arrivals. Research was undertaken by one of the authors, to explore the opinions of the accommodation sector about current education provisions and the future direction that courses should take. Integration of all stakeholders in the implementation of the broad education policy outlined by the government is crucial to improving hospitality education in Grenada to ensure a competitive tourism industry.
