Void Node Detection and Packet Re-routing in Underwater Wireless Sensor Network
Main Article Content
Underwater wireless sensor networks (UWSNs) have been appeared as an encouraging innovation to screen and investigate the seas in lieu of customary undersea wire line instruments. All things considered, the information social occasion of UWSNs is still seriously restricted in light of the acoustic channel correspondence attributes. One approach to improve the information assortment in UWSNs is through the plan of directing conventions thinking about the special attributes of the underwater acoustic correspondence and the exceptionally unique organization geography. In this paper, we propose the GEDAR steering convention for UWSNs. GEDAR is an anycast, geographic and deft steering convention that courses information parcels from sensor hubs to numerous sonobuoys (sinks) at the ocean's surface. At the point when the hub is in a correspondence void area, GEDAR changes to the recuperation mode strategy which depends on geography control through the profundity change of the void hubs, rather than the customary methodologies utilizing control messages to find and keep up steering ways along void locales. Reproduction results show that GEDAR altogether improves the organization execution when contrasted and the pattern arrangements, even in hard and troublesome versatile situations of inadequate and extremely thick networks and for high organization traffic loads.
