Internet of Things (IoT) mainly concentrates on automation and increases tension free life. It has enormous effect on public such that every individual depend on IoT to meet their requirements like daily purchase, ticket booking, and online transfers. Internet plays very important role here in establishing inter communication between the elements present in the network of the devices. Some of the devices on the network interfaces with the internet to predict the next parameter at the device and to control the passive devices. Interfacing smart devices with user mind and electronic gadgets require high speed internet. This can be implemented with most sophisticated peripherals categorised like sensors, transducers, microcontrollers, and communication devices. In the present work the device management, control, applications, limitations is discussed along with internetwork. The present paper mainly concentrates on essential design considerations and limitations to improve the IoT in an organization or a city to provide superior experience to the customer.

Examples of such applications include multimedia archives, military image processing, and medical image processing for electronic patient records (EPRs). High capacity watermarking is proposed in the paper and implemented using integer to integer wavelet transform. The proposed scheme divides an input image into non-overlapping blocks and embeds a watermark into the high frequency wavelet coefficients of each block. The conditions to avoid both underflow and overflow in the spatial domain are derived for an arbitrary wavelet and block size. The experimental results show that the implemented scheme achieves higher embedding capacity while maintaining distortion at a lower level than the existing invertible watermarking schemes.

The forest rangers find it very hard to track the tigers. The combination of Wireless technology, Adhoc Networks and GIS can be helpful in this aspect. We propose a system that uses a combination of Adhoc network, GPS & GIS technologies to help the forest rangers in tracking & identification of the tigers. The primary focus is on the advantages that Adhoc Networks offer. The Communication between the animal's device and the user can be via GSM cellular network which allows real-time tracking. The communication in forest like remote areas can be established using Ad-hoc networks.

Traditionally ranking models are based on a static snapshot of the Web graph, which is basically the link structure of the Web documents. The visitor's browsing activities is directly related to importance of the document. However in this traditional static model the document importance on account of interactive browsing is neglected. Thus this model lacks the ability of taking advantage of user interaction for document ranking. In this paper we propose a model based on semantic web to improve the local ranking of the Web documents. This model works on Ant Colony algorithm to enable the Web servers to interact with Web surfers and thus improve the local ranking of Web documents. The local ranking then can be used to generate the global Web ranking.
