The deployment of sensor nodes is either in uniform or in random fashion that is defined by the requirements and the available situation.
Their line of sight communication range is 75 to 100 m with a 1/2 wave dipole antenna in the outdoor environment.
Further, they are analyzed along with the suggested improvements for the researchers.
At the end, we presented our previously published research work as an example and case study of discussed factors.
WSN technology that is encapsulating such a long list of qualities is now in action with lots of mind-blowing applications by indulging it in various fabrics of life.
The cradle of WSN research was first nourished by Defense Advanced Research Projects Agency (DARPA) through the military applications.In this survey article, we are targeting an innovative aspect of analysis on routing in wireless sensor network (WSN) that has never been seen in the available literature before.This article can be a guiding light for new researchers to comprehend the WSN technology, energy aware routing, and the factors that affect the energy aware routing in WSN.It continued to explore this technology by funding some prominent research projects, for example, Smart Dust  and Network Embedded System Technology .Some other important real-world applications/projects of WSN  are Wave Monitoring , Ocean Water Monitoring , Zebra Net , Cattle Herding , and neu RFon .A rich list of references is also cited for interested readers to explore the related given points.A typical node is made up of a mote and a sensor board along with battery and a memory device.The network nodes establish communication links with each other nodes in their footprint through the omnidirectional full duplex antenna.This cooperative interaction among the network nodes covers the whole network that gives birth to the self-synchronization, self-organizing, and self-adaptive capabilities of wireless sensor network.In wireless sensor network, nodes are uniformly or stochastically (randomly) deployed in the target region.Interconnection of nodes in a decentralized fashion without following any preexisting infrastructure is named as an ad hoc network.
