Abstract :

The location in a mobile ad-hoc network, where each node needs to maintain its location information. which frequently updating its location information within its neighboring region, which is called neighborhood update (NU).and updating its location information to certain distributed location server in the network, which is called location server update (LSU). The operation costs in location updates and the performance losses of the target application due to location application costs which imposes question for nodes to decide the optimal strategy to update the location information, where the optimality is used for minimizing the costs. The location update decision problem is modeled as a Markov Decision Process (MDP). The monotonicity properties of optimal NU and LSU operations with respect to location application cost under a general cost setting. Separable cost structure shows the location update decisions of NU and LSU. Which can be independently carried out without loss of optimality that is a separation property. From the separation property of the problem structure and the monotonicity properties of optimal actions which finds that 1) there always exists a simple optimal update rule for LSU operations 2) for NU operations. If no prior knowledge of the MDP model is available, then also it introduces a model-free learning approach to find a near-optimal solution for the problem.
