Review of Shortest Path Wireless Sensor Network Performance with Energy-Efficient Approaches

Improving the lifetime of a WSN which works in very cruel conditions, is one of the key difficulties looked by scientists and engineers of remote sensor network advancements. Dragging out the lifetime of WSN becomes considerably more significant in some delicate regions where re-energizing or supplanting the sensor hub batteries is unimaginable or not viable. In this proposition, the issue of improving the WSN's lifetime is examined and is accomplished utilizing geography control calculations, which plan the sensors to preserve battery power mounted on them. Disjoint set K cover age method is applied for building the new and diminished geography that contains not many sensor hubs in dynamic state while taking care of the remainder of the hubs state. The idea of disjoint set K covers is utilized, where not many sensors are actuated and others are deactivated to save battery power for some time later. The sensors conveyed are isolated to frame a most extreme number of disjoint sensor subgroups and every subgroup is actuated for one discrete time-frame while different gatherings are in the rest mode to save the battery power.
