MQoSR: A Multiobjective QoS Routing Protocol for Wireless Sensor Networks

Algorithm 2

Select number of used paths.

𝑛= number of available disjoint paths (source to sink)

𝑅_e2e = 1;               // Initialization

𝑛𝑝 = 0;                  // Initialization

for (p = 1; p ≤ n; p++)

         {

     𝑅_e2e=𝑅_e2e×(1−𝑅_path𝑝)// Calculate 𝑅_e2e according to (7)

     np = np++; // Add another path to the used paths

     𝑖𝑓 ((1 −𝑅_e2e) ≥ 𝑅_req)

    {

    number of paths to be used = np;
