CCIC-WSN: An Architecture for Single Channel Cluster-based Information-Centric Wireless Sensor Networks

Towards information-centric WSN simulations

In pursuance of integrating Wireless Sensor Networks (WSNs) with other systems, the use of techniques from other fields, such as machine learning and information processing, are becoming more common. Therefore, we faced the problem of missing network simulations that are not only focused on the packet exchange between network elements, but also in the data that is transmitted between them. In other words, we needed a tool that evaluated the WSNs on how they evolve and react to the environmental changes. To illustrate the benefits of having such perspective, we explain the kind of simulation pr…

Measurement and Prediction of Centrical/Peripheral Network Properties based on Regression Analysis - A Parametric Foundation for Performance Self-Management in WSNs

Predicting performance-related behavior of the underlying network structure becomes more and more indispensable in terms of the aspired application outcome quality. However, the reliable forecast of QoS metrics like packet transfer delay in wireless network systems is still a challenging task. Even though existing approaches are technically capable of determining such network properties under certain assumptions, they mostly abstract away from primal aspects that inherently have an essential impact on temporal network performance dynamics. Also, they usually require auxiliary resources to be i…

A review on routing protocols for application in wireless sensor networks

Wireless sensor networks are harshly restricted by storage capacity, energy and computing power. So it is essential to design effective and energy aware protocol in order to enhance the network lifetime. In this paper, a review on routing protocol in WSNs is carried out which are classified as data-centric, hierarchical and location based depending on the network structure. Then some of the multipath routing protocols which are widely used in WSNs to improve network performance are also discussed. Advantages and disadvantages of each routing algorithm are discussed thereafter. Furthermore, thi…

Sensors Lifetime Enhancement Techniques in Wireless Sensor Networks - A Survey

Wireless Sensor Networks are basically used for gathering information needed by smart environments but they are particularly useful in unattended situations where terrain, climate and other environmental constraints may hinder in the deployment of wired/conventional networks. Unlike traditional networks, these sensor networks do not have a continuous power supply at their disposal. Rather the individual sensors are battery operated and the lifetime of the individual sensors and thus the overall network depend heavily on duty cycle of these sensors. Analysis on WSNs shows that communication mod…

Behavior of Wireless Body-to-Body Networks Routing Strategies for Public Protection and Disaster Relief

Critical and public safety operations require real-time data transfer from the incident area(s) to the distant operations command center going through the evacuation and medical support areas. Any delay in communication may cause significant loss. In some cases, it is anticipated that the existing communication infrastructures can be damaged or out-of-service. It is thus required to deploy tactical ad-hoc networks to cover the operation zones. Routing data over the deployed network is a significant challenge with consideration to the operations conditions. In this paper we evaluate the perform…
