Extension of Lifespan in WSN


Objectives: Since Wireless Sensor Network has played a crucial role in our life, further research is needed to enhance its performance. For missions to be accomplished successfully, the lifetime span has to be prolonged. The lifetime of WSNs is considered a crucial issue that has to be studied further. Methods/Findings: Thus, numerous researches from different perspectives have been proposed. In this study and research, it has been found that there is a harmful process called sink isolation (hotspot zone) because of neighbor nodes of sink running out of energy more than the others. Our point of view is that these hotspot zones are of more concern than far away zones. Thus, a pioneering Q-metric is studied which tackles the energy consumption at each hotspot zone relative to the dimension of its interconnected nodes at the far away zone. Application: Accordingly, the Q can be manipulated to switch data traffic to alternative routes lead to a more proper hotspot zone and hence an exhausted hotspot zones will be avoided and consequently lifetime of this network will be extended.
