One of the biggest challenge in geographic routing protocols is the design of efficient distributed location services that can locate the positions of mobile nodes. The accurate positioning of mobile nodes in MANETs is important to location service scheme since they are related to efficiency of routing protocols. We propose a grid-based predictive Location Service (GPLS) scheme and a hole-tolerant grid-based predictive Location Service (GPLS-H) scheme. In proposed location service scheme GPLS and GPLS-H, the network is partitioned into grids and grids are divided into groups by using a HASH function, which guarantees the uniform distribution of location servers of a node in the network. The main contribution of this paper is that the proposed location service scheme GPLS and GPLS-H provide accurate location query capability by means of location prediction of mobile nodes and GPLS-H can tolerate the "holes” in grid networks. The simulation results show that the location service scheme GPLS and GPLS-H have better performance than CRLS and SLURP in query success ratio, query delay and location availability.
