Amir M. Jafari, Adam Sklorz, Walter Lang · Journal of Networks · 2009
Abstract—Wireless sensors implementation in process automation applications is a forwarding step for wireless sensor network. Autonomous network structure is considered as an option for such implementation. Autonomous wireless sensor/actuator networks require a target-oriented routing algorithm. In the first section the perception of autonomous network with an example is explained. It is clarified which features from the routing algorithm are expected. In the second section, Sequential Coordinate Routing Algorithm (SCAR) is proposed and its development, functionality and properties are discussed. Besides the target-oriented property as a main feature of the SCAR, based on the mathematical claim and its proof, it is shown how the minimum energy consumption is taken into consideration. By realizing the core of the routing algorithm, it is presented that not only void problem does not exist like other algorithms but also it is easy to compute. By this algorithm any two nodes are able to communicate to each other without need to pass message through central node of the network.
