Smart dust is a tiny dust size device with extraordinary capabilities. Smart dust combines sensing, computing, wireless communication capabilities and autonomous power supply within volume of only few millimeters and that too at low cost. These devices are proposed to be so small and light in weight that they can remain suspended in the environment like an ordinary dust particle. These properties of Smart Dust will render it useful in monitoring real world phenomenon without disturbing the original process to an observable extends. Presently the achievable size of Smart Dust is about 5mm cube, but we hope that it will eventually be as small as pack of dust. Individual sensors of smart dust are often referred to as motes because of their small size. These devices are also known as MEMS, which stands for micro electro-mechanical sensors.

Several studies and reports of a smart dustbin are out there to reduce human efficiency and to make the city clean. Here, we will be using the idea of a smart dustbin using IoT and different sensors and work on it to make it even more effective. Each dustbin shall have the data of the distance and the filled percentage of all other dustbins, aligned to it, in its memory. When it'll be filled up to 75% or 90%, which we'll know by the Ultrasonic Sensor, it'll send a signal to the municipality about its content. When the dustbin shall be 100% filled, it'll send a signal to the municipality to empty it. The now brimmed dustbin shall display a message on the attached LCD of the nearest dustbin which is not full, along with the distance and the direction in which it resides. The dustbin calculates the closest distance from the data saved in the memory and at the same time checks if the other dustbins are filled completely or not. If both the conditions match, it displays the number and direction of that dustbin. This implementation is introduced so that people don't dump their trash in front of the filled dustbin, rather find a nearby one. This framework helps to make the city clean in an effective way.

In this paper we present a modular and extensible visualization framework for wireless sensor networks. These networks have typically no means of visualizing their internal state, sensor readings or computational results. Visualization is therefore a key issue to develop and operate these networks. Data emitted by individual sensor nodes is collected by gateway software running on a machine in the sensor network. It is then passed on via TCP/IP to the visualization software on a potentially remote machine. Visualization plug-ins can register to different data types, and visualize the information using a flexible multi-layer mechanism that renders the information on a canvas. Developers can easily adapt existing or develop new custom tailored plug-ins for their specific visualization needs and applications.

We introduce a novel amortization technique for computation of consecutive preimages of hash chains, given knowledge of the seed. While all previously known techniques have a memory-times-computational complexity of O(n) per chain element, the complexity of our technique can be upper bounded at O(log 2 n), making it a useful primitive for low-cost applications such as authentication, signatures and micro-payments. Our technique uses a logarithmic number of pebbles associated with points on the hash chain. The locations of these pebbles are modified over time.

Abstract With the advent of unbounded small-scale dust sensors being deployed in wireless sensor networks, existing authentication protocols for ordinary wireless sensor networks are becoming less efficient for dust sensors. Resource constrained dust nodes must do anything in cooperation with other nodes. Existing key management protocols require large key storage in each node, which cannot be stored in smart dust sensor nodes with strictly limited resources. Given the practical fact that adversaries or non-adversaries cannot retrieve ...

Futurists predict the use of Smart Matter, nano-technology with computational ability, as pervasive. It will be painted on the surfaces of our environments, and the futurists suggest that these surfaces will be used as video displays, user interfaces, and sensor arrays. The implication is that a coat of paint will be enough to add this functionality to a surface. The field of Amorphous Computing provides one possible realisation of this vision; an amorphous computer is a multitude of identical tiny computers with local communication capability, and can be painted onto a surface to form an ad hoc network. An iSurface is a specialised version of an amorphous computer, using a simulator with a physical grounding. In this paper we argue that such a vision of Intelligent Surfaces is fundamentally flawed. The load, both in terms of processing and communication, on the individual elements will always be a hindrance to responsiveness of iSurface applications, and we present experimentation on several applications to demonstrate this.
