CAF: Cluster Algorithm and A-Star with Fuzzy Approach for Lifetime Enhancement in Wireless Sensor Networks

Figure 9

Flowchart of the AF algorithm, where distance (𝑖,𝑗) is the distance between the node 𝑖 and one of its neighboring nodes 𝑗. RP(𝑖,𝑗) and TN(𝑖,𝑗) are the remaining energy and traffic load of the neighboring node 𝑗 of node 𝑖, respectively. Pro(𝑖,𝑗) is the node cost of the neighboring node 𝑗 of node 𝑖.
