A novel algorithm MSDG(Mobile Sink-based Data Gathering)which based on mobile sink data gathering does not depend on the location of nodes,is proposed in mobile wireless sensor networks(WSNs).It solves thehot spotproblem,that is multi-hop routing in WSNs brings to energy hole.Sink node builds the routing tree along the nearest fixed node as root node.At the same time,the sensed data in cluster node carry on data fusion calculation through the cluster,thus the data fusion is flanked by trees to send to Sink node in reverse-by-jump.Simulation results show that in the aspect of average energy consumption and network lifetime,the performance of MSDG surpasses data gathering protocols of LEACH and ACE-L.
