Chapter 1 Introduction During last few decades‚ booming of wireless sensor network (WSN) require a reliable power source. Generally the power sources to these microsystems are the conventional battery. However‚ the battery has a finite lifespan and once extinguished of its power‚ these sensors must be retrieved and the battery replaced [1]. With these sensors being placed in remote location it can become an expensive task to obtain and replace the battery. Therefore‚ it becomes necessary to provide

Marketing Strategy and Plan – Session 6 Gillette’s Launch of Sensor The introduction of the Sensor Shaving System‚ one of the biggest product launches ever‚ forced Gillette to reevaluate its strategy in its shaving and non-shaving business. It had to decide whether to go ahead with the launch and if so‚ at what scale. Gillette’s top management had to make very important decisions regarding the launch of its Sensor line. They are questioning‚ on which markets to focus their launch‚ how aggressive

certain distance. This paper also aims at reducing road accidents by detecting consumption of alcohol by the driver. This can be implemented using alcohol sensor module which contains skin sensor‚ breath alcohol sensor and proximity sensor. The skin sensor and breadth alcohol sensor detects the presence of alcohol content and the proximity sensor helps in detecting any kind of malpractice. The novelty of this paper is to effectively reduce the energy consumption of the street lights by controlling

Computer Abstract—Energy consumption of nodes is a crucial factor that constrains the networks life time for Wireless Sensor Networks (WSNs). WSNs are composed of small sensors equipped with lowpower devices‚ and have limited battery power supply. The main concern in existing architectural and optimisation studies is to prolong the network lifetime. The lifetime of the sensor nodes is affected by different components such as the microprocessor‚ the sensing module and the wireless transmitter/receiver

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
