In this paper, we intend to focus on the sensor network applications in firefighting. A distributed algorithm is developed for the sensor network to guide firefighters through a burning area. The sensor network models the danger of the area under coverage as obstacles, and has the property to adapt itself against possible changes. The protocol developed, will integrate the artificial potential ...

Wireless sensor nodes are electronic devices capable of collecting, storing, and processing environmental information, and communicating with other sensor nodes through wireless communications. Hundreds or thousands of wireless sensor nodes deployed in a region of interest comprise a wireless sensor network (WSN), where all members cooperatively monitor the whole region, barriers, or targets (p...

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...
