random sensor node deployment scenarios to find the sinks locations for a particular sensor nodes deployment. We have considered a 4x4 square grid wireless sensor network‚ where sinks and sensor nodes both are static. Locations of the sinks are deterministically placed. Locations of our sinks are taken from our deterministic sensor node deployment approach for 4x4 square grid region‚ where the network is 1-hop and 2-covered. Sinks are placed deterministically on grid cross points. But the sensor node

Previous MAC protocols for sensor networks assume static sensor nodes and focus on energyefficiency. In this paper‚ we present a mobilityadaptive‚ collision-free medium access control protocol (MMAC) for mobile sensor networks

Chapter 1 INTRODUCTION 1.1 Background of the Study Mankind has always tried to use technologies in order to improve his life. The wheel‚ for instance‚ was invented in order to transport goods saving forces and to move more quickly. The discovery of fire helped to heat him and to defend himself from wild animals. From the very beginning man has always looked for a better way of life. Time after time‚ he has continued to improve his environment‚ both at work and at home. The first automations

field of computer networks and would like to specialize in it. The logic in it is truly uncomplicated and yet water-tight. My first brush with practical execution occurred as early as in the 3rd semester‚ while making an autonomous robot with sensors programmed through the computer parallel port. However‚ it did not work as intended. After gaining considerable knowledge and experience‚ I built another robot‚ this time with an on-board processor. Programming it was‚ beyond doubt‚ a daunting task

Wireless Sensor Networks “Sensor networks are the key to gathering the information needed by smart environments‚ whether in buildings‚ utilities‚ industrial‚ home‚ shipboard‚ transportation systems automation‚ or elsewhere. Recent terrorist and guerrilla warfare countermeasures require distributed networks of sensors that can be deployed using‚ e.g. aircraft‚ and have self-organizing capabilities. In such applications‚ running wires or cabling is usually impractical. A sensor network is required

Furthermore‚ this system also can control the intensity of house lamp with the related sensor. This idea is come from the GO GREEN Concept. As we know‚ our mother earth is being polluted‚ and the main cause is from the greenhouse effect. So‚ it is important to save the electricity and reduce it usage in order to reduce the greenhouse
