In this thesis, we review the data routing techniques and related issues in wireless sensor networks. After supplying a basic background about the wireless sensor and actuator networks, data routing techniques required by sensor and actuator networks is introduced to constitute an infrastructure of our scheme. In our protocol actuators broadcast a task registration message for the sensed data that they need. While the task registration message is being disseminated through the network, the sensor nodes relaying the message construct a multicast tree for each actuator and sensing task. A node that receives a sensed data packet forwards it to the neighboring nodes that relay a registration message for the related task. Our scheme can also adapt itself to the changes in the number, the locations, and the sensing task interests of the actuators, and the power available in the nodes.
