Routing operations in wireless body area networks with fuzzy logic approach

It is important to use healthy communication and appropriate routing techniques to increase performance in wireless body area networks. At present, the biggest problem of sensor nodes that bring such networks into the uneasiness is limited energy resources. In this paper, it is proposed to make road selection by calculating the distances of the nodes and the battery levels while making the routing decisions. The fuzzy logic controller and the “neighbor element selection” between the nodes were created as output values. Later, nodes were enabled to select an active path. Fuzzy logic decision mechanism was applied in the operations. By simulating such networks, sample scenarios were set up for routing test operations. As a result, nodes were observed to survive longer. The network life was extended and more data transmission was provided than the frequently used AODV protocol.
