Position coodinate-based energy efficient routing protocol for Wireless Sensor Networks

Conventional Routing Protocols proposed for Wireless Sensor Networks cannot fully accommodate the characteristics of WSNs. In particular, although it is possible to in the solution of energy consumption and global ID problems through applying position information, there are few protocols that actively apply such position information. In the case of the GEAR(Geographical and Energy Aware Routing),a typical algorithm, which uses positioning information, it does not fully represent the characteristics of WSNs. It is because it is limited to forward query messages and assumed as fixed network environments. The routing protocols proposed in this paper defines the direction of data, which is routed based on the position information of individual and sink nodes, in which each node configures its paths based on this direction and routes signals. Because it performs data-centric routing position information, it does not require certain global IDs in order to verify individual nodes and is able to avoid unnecessary energy consumption due to the forwarding of packets by defining its direction.
