AB  - An energy-efficient flooding mechanism termed Adaptive Location Aided Flooding (ALAF) for wireless sensor networks is proposed in this paper. This protocol uses location information to reduce redundant transmissions, thereby saving energy. The sensor network is divided into non-uniform virtual grids and each sensor node associates itself with a virtual grid based on its location. In areas with dense node deployment smaller sized grids are maintained. Sensor nodes within a virtual grid are classified as either gateway nodes or internal nodes. While gateway nodes are responsible for forwarding the data across virtual grids, internal nodes forward the data within a virtual grid. The proposed approach ALAF, achieves energy savings by reducing the redundant transmissions of the same packet by a node. The performance of ALAF for different grid sizes and different node densities are studied. It is compared with other well-known methods. Thus it can be shown that ALAF saves significant amount of energy when compared to prior methods.
