Abstract:
A wireless sensor network is a network of many small nodes that are capable of sensing relative data in a particular environment and geographical location and can perform some computations on these data. The ability to sense and read data in environments where some factors are monitored has made WSN prominent and increase in its adoption in diverse fields like health, military, surveillance, disaster management, tracking. These networks run on the limited power supply and many efforts have been put in place to ensure energy-efficient network. The power challenge of these networks has resulted in the development of several energy-efficient algorithms to effectively utilize the limited power of the nodes. In this paper, trends, as well as challenges of WSNs, were discussed and pointed out. Future steps and directions were also discussed in the paper.
