GSA: node failures tolerent spatial window query processing algorithm in wireless sensor networks

A node failures tolerent spatial window query processing algorithm called GSA was proposed. The grid size parameter was studied and a grid-based data collection schedule scheme to avoid the message collisions in the process of data collection was proposed. Finally, the influence of node density, the...
