adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...

Hitherto, instrumentation network design methodologies have been based solely upon sensor capital costs. Within this framework the cost of new instrumentation is minimized subject to constraints indicating the desired level of performance. While, these formulations account for the cost of a network, they do not reflect the potential benefit of adding sensors. To capture this potential profit, w...

Remote sensing technologies have long since been relegated to the implementation of airborne, or spaceborne configurations. We recognize that distributed sensors in all configurations can contribute to improved sensor performance and expanded measurement configurations. These new sensor systems require designs that can be scaled to hundreds to potentially thousands of individual sensors or sens...

Wireless Sensor Networks impose additional challenges on Media Access Control mechanisms. Many schemes have been proposed that use either CSMA or TDMA protocols; however design of a CSMA protocol for WSNs must be more than a general purpose mechanism. In this work, we analyze the parameters of a CSMA layer and their affect on performance. We examine how to use upcalls to notify applications of ...
