A Sensor network is composed of sensor nodes and sink nodes. Since the sensor nodes have limited resources a routing method should be energy efficient. Also it is simple and applicable to many sensor nodes. A location-based routing protocol, where each sensor uses its location and that of neighbor nodes to transmit data to a destination, can support a variety of application services with its efficient routing and ability to increase the scalability ofnetwork. This paper suggests a routing protocol that can achieve an efficient data transmission from source to the mobile sink node without interruption by using location based virtual grid. In case there are holes in the sensor network, routing is maintained by using relative landmarks to bypass the holes. A simulation of performance evaluation demonstrates the superiority of the suggested method to the previous ones.
