OPTICS Based Coverage in Wireless Sensor Network

This paper deals with the coverage problem of wireless sensor network. We use the density based clustering technique OPTICS to cover a target region with less number of sensor nodes. OPTICS works well to identify the outliers, core points and it obtains the denser regions. We define a level of acceptance to find next appropriate sensor in the region. We eliminate overlapped area and obtain a de...

General-Purpose Wireless Distance Sensor

Thanks to the availability of different wireless communication techniques, external devices can extend today’s smartphones. Such an external device can be any kind of a sensor, for example. This thesis describes a general-purpose wireless distance sensor, which connects to a smartphone or any other device equipped with Bluetooth technology. Further, an Android application which handles the meas...

A Fuzzy Based Priority Approach in Mobile Sensor Network Coverage

In this paper a new fuzzy based approach for improving network coverage in wireless mobile sensor networks is proposed. In the proposed approach firstly each mobile sensor node determines its neighbors and its distance from borders and obstacles. According to these values, fuzzy inference engine calculates the priority of node for movement. Then according to the priority, in turn, nodes move aw...

Sensor Network Coverage Restoration

Wireless sensor networks are emerging as a new computational platform consisting of small, low-power and inexpensive nodes used in a broad set of application areas including environmental monitoring, habitat monitoring and disaster recovery. Typically sensor nodes are deployed over a geographical area for the purpose of detecting, tracking and monitoring events of interest. Since sensor nodes a...
