The solve this kind of problem you just need to improve the method of clustering so that the energy consume for transmission will be less

Aliyu Zakariyya:

What if we use star topology not hierarchical network architecture?

By using star topology there is high possibility for encountering hotspot problem due to simultaneous request from each cluster head to sink so to avoid that you can apply multilevel clusters scenarios

Hi Heba,

I'm not sure if I understand the question but I found the following paper, maybe could be useful as starting point:

Bottleneck around Base Station in Wireless Sensor Network and its Solution (https://doi.org/10.1109/MOBIQW.2006.361777)
