Description
Summary:This paper mainly studies mobile sink-based data gathering protocol, according to mobile wireless sensor network model, adopts a joint strategy of sink mobility and routing to realize high-efficient data gathering based on which nodes in network are divided into certain number of clusters, demonstrates that in the square monitoring area with any side-length L, the minimum energy consumption of the network is used for data gathering when sink nodes move along the path. In the presented MSDG(Mobile Sink-based data gathering), sink chooses the closest fixed nodes along the path as roots to build a routing tree dynamically, cluster-heads gather the data of all common nodes within cluster and perform data aggregation, the aggregated data is sent to sink reversely by tree. The simulation shows that the performance of MSDG is better than other data gathering protocols in terms of average energy consumption and network lifetime.
