Robust Recovery of Data in Multiple Sink Wireless Sensor Network

Jyothi.K | Sridhar K ^[4]

Abstract: Multi-Sink Sensor network is one where the whole area is divided into subset of regions where each region has a sink and data is collected from sources of every region by the sink transmitted to base station by sink with the help of intermediate nodes. However if certain nodes in an area fails which are participated in routing; then a void region gets created and data is not transmitted to base station from that area. The unteachability problem (i. e. ; the so-called void problem) that exists has been studied for the wireless sensor networks. Some of the current research work cannot fully resolve the void problem; while there exist other schemes that can guarantee the delivery of packets with the excessive consumption of control overheads. Moreover; the hop count reduction (HCR) scheme is utilized as a short-cutting technique to reduce the routing hops by listening to the neighbors traffic; while the intersection navigation (IN) mechanism is proposed to obtain the best rolling direction for boundary traversal with the adoption of shortest path criterion. This paper presents a robust recovery mechanism of nodes failure in a certain region of the network during data delivery. It dynamically finds new node to route data from source nodes to sink. We simulate the proposed system with oment and shows that the variant is better performer in void scenario
