Abstract: WSN consist of tiny light weighted sensors, which have been used in several applications for sensing real-time data, and forward the aggregated data to sink or base station. Since wsn are energy constrain, the key challenging is to extend network lifetime and to balance the nodes energy levels. In multihop routing, the nodes near to a static sink consume more power and become unbalanced due to more energy drain. To alleviate energy problems, mobility of the sink has been accepted as efficient way. Making sink mobile, provided best solution for balancing the network. In this paper we propose a new approach to extend network lifetime by relocating sink node near to bottleneck nodes which limits the network lifetime by disjoint links. The key concept is to target the set of node disjoint links which stops functioning due to low energy level, proposed algorithm finds disjoint links and triggers sink to relocate its position to connect nodes with minimum hop. The extensive simulation has been carried out to analyse proposed system and compared with EASR method.
