Challenges in Wireless Sensor Networks - Overview

Wireless sensor networks can be found almost everywhere. They consist of small devices, known as sensor nodes, which are arranged in the desired environment. They collect information and send it to the client through a network gateway using a routing protocol. These networks have many good characteristics like quality of service (QoS), reliability, low power consumption, flexibility, scalability, etc. Despite these good characteristics, many problems and challenges are plaguing these networks. Challenges depend on the type of network, and each network has its problems. Connecting wireless sensor networks to the Internet of Things also leads to new challenges. Security is one of the main problems plaguing these networks, but it is also one of the most difficult challenges due to network limitations. In addition to safety, the biggest challenge is still consuming energy because it is not always possible to charge the battery, so the sensor nodes die. Another more serious challenge is the real-time transmission. Traditional wireless sensor networks do not work in real-time, and even if they need to work in real-time, they avoid it. The Internet of Things works in real-time, so it needs real-time wireless sensor networks.
