The route between source and destination, source identity and destination identity are hide by means of anonymous routing protocols. Anonymous routing protocols use hop by hop encryption or redundant traffic in the existing system, which may cause high cost and it doesn’t provide different anonymity protection to source, destination and route. So, we propose a protocol called Anonymous Location Based Efficient Routing Protocol (ALERT). The main technique used to provide anonymity is hierarchical partition. ALERT dynamically partition the network into vertical/horizontal zone. Even though this hierarchical zone partition is used, the security criteria is not satisfied .there may be a chances in node misbehavior .so we propose another concept by trust based node selection. The security rules are generated to select the random node to carry the packet. The security rules consist of logical rules and physical rules. The Greedy perimeter stateless algorithm (GPSR) is used to transmit the data from one node to another. It also effectively avoids the counter intersection attacks and timing attacks. Here we use two rules to securely select the node which relay between source and destination. The two rules are physical and logical rules. NS2 simulation result shows the efficiency of ALERT protocol which used in MANET.
