Abstract
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.

Highlights
In last so many years, a large research has addressed the prospective of alliance among sensors in data collection as well as its processing and the coordination and management of the sensing activity were conducted.most of the sensor nodes are restricted in energy supply as well as data transmission rate
Initial deployments of Wireless Sensor Networks (WSNs) were based on a many-to-one communication paradigm, where a single sink gathers the data from the different data sources
Positioning and energy-efficient Routing mechanism have been proposed in WSN
Summary
In last so many years, a large research has addressed the prospective of alliance among sensors in data collection as well as its processing and the coordination and management of the sensing activity were conducted. One of the issues that are addressed by WSN interested researcher is that tree topology routing tables are not required to send the packet to the destination and just blindly follows this designed tree to its intended destination (sink) even if the destination itself has located nearby the forward nodes[9]. In 13 design a mathematical model that determine sinks’ locations to minimizing the sensors’ average route distance According to their requests it builds efficient routes with high sharing degree from the coordinator to multiple sink nodes. The vast majority of research in particular WSNs with multiple sinks aims to extend the lifetime either through topology manageability or routing mechanism independently
