Presently available schemes for data centric storage in sensor networks usually use geographical routing protocols to communicate data between sensor nodes. However, sensor nodes are required to know their locations for them to use geographical routing protocols. In this paper, we propose a new routing protocol that does not rely on location information, and thus can be used for data centric storage...
In this paper, we propose a new data centric storage using multilevel grid techniques for sensor network. The proposed method solves the hot-spot problems of existing data centric storages. By exploiting multilevel grid techniques, we lower or elevate the grid level of certain area according to the work load of sensor nodes. The level of a hot spot area is lowered so as that more sensor nodes cooperate...
