Wireless sensor networks (WSNs) have recently achieved a great deal of attention due to its numerous attractive applications in many different fields. Sensors and WSNs possesses a number of special characteristics that make them very promising in many applications, but also put on them lots of constraints that make issues in sensor network particularly difficult. These issues may include topolo...

In many applications it is necessary to have some guarantees on the coverage, connectivity and lifetime of the Wireless Sensor Networks(WSN). Coverage problem is regarding how to ensure that each of the points in the region to be monitored is covered by the sensors. In maximizing coverage, the sensors need to be placed not too close to each other so that the sensing capability of the network is...

It is important to monitor compound event by barrier coverage issues in wireless sensor networks (WSNs). Compound event barrier coverage (CEBC) is a novel coverage problem. Unlike traditional ones, the data of compound event barrier coverage comes from different types of sensors. It will be subject to multiple constraints under complex conditions in real-world applications. The main objective o...

These days, many WiFi devices are trying to generate high throughput and have longer signal coverage which also bring unnecessary signal interference to neighboring wireless networks, and result in decreased network throughput. Signal interference could be minimized by reducing signal coverage of wireless devices. On the other hand, small signal coverage means low transmission power and low dat...
