Applying Artificial Immune Systems for Deploying Router Nodes in Wireless Networks in the Presence of Obstacles

摘要

This work deals with the deploying of router nodes using artificial immune systems techniques, particularly for industrial applications of wireless sensor networks. Possible scenarios include configurations with sensors blocked by obstacles. These nodes make possible the transmission of data from sensors to the gateway in order to meet criteria especially those that lead to a low degree of failure and reducing the number of retransmissions by the routers. These criteria can be set individually or in groups, associated with weights. Router nodes deploying is accomplished in two phases, the first uses immune networks concepts and the second employs potential fields ideas for deploying the routers in such way that critical sensors attract them while obstacles and other routers repel them. A large number of case studies were considered from which some representative ones were selected to illustrate the method, for different configurations in the presence of obstacles.
