Abstract:
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.
