A wireless device network may be a massive assortment of device nodes with restricted power and forced procedure capability. As a result of the restricted communication vary and high density of device nodes, packet forwarding in device networks is sometimes performed through multi-hop information transmission. Therefore, routing in wireless device networks has been thought of a crucial field of analysis over the past decade. Nowadays, multipath routing approach is wide employed in wireless device networks to boost network performance through economical utilization of accessible network resources. Consequently, the main aim of this survey is to gift the conception of the multipath routing approach and its basic challenges, yet because the basic motivations for utilizing this method in wireless device networks. Wireless device Networks (WSNs), is one amongst the foremost speedily growing scientific domain. This is often due to the event of advanced device nodes with very low price and also the potential applications of such device nodes area unit ever growing. WSNs area unit internet of device nodes with a collection of processors and restricted memory unit embedded in it. Reliable routing of packets from device nodes to its base station is that the most significant task for these networks. Routing in WSN is bit additional advanced than different wired or wireless networks. The study concludes with comparison of few distributed agglomeration algorithms in WSNs supported these metrics.
