A Reliable Clustering Based Energy Efficient Path Selection Method with Multiple Mobile Sink

Wireless sensor networks are equipped with tiny, irreplaceable batteries and therefore it is necessary to design energy efficient methods to prolong the network lifetime. In wireless sensor networks (WSNs), the sink mobility along a constrained path can improve the energy efficiency. Sink mobility is an important technique to improve the sensor network performance. Existing method used weighted rendezvous planning (WRP) along with single mobile sink. In this method the mobility of mobile sink is restricted to RPs (the nodes having highest weight). This method focus on single mobile sink. This leads to inefficient communication and reducing the network lifetime. To deal this problems, multiple mobile sink clustering based WRP method is proposed. In this method network region is partitioned into smaller areas and assign CH and mobile sink for each regions and it achieves better reduction in energy consumption and improves the network lifetime. Extensive Simulation are conducted using Network Simulator-2 to verify its efficiency and performance.
