## 5 Performance Analysis
\(EC(SSn)\) represents the energy consumption for single sensor node \(Sn_{i}\). * Impact on Cost: It is defined as the amount of memory consumed to perform efficient power system monitoring with the help of sensor nodes. It is measured in terms of megabytes. It is formulated as \[Cost=\sum_{i=1}^{n}S_{n_{i}}\times\text{Memory(consumed by one sensor node)}\] (4) From (4), the Cost \(Cost\) is determined. \(Sn_{i}\) refers to each individual sensor node \(i\) in the network. \(n\) indicates the number of sensor nodes \(Sn_{i}\), and \(Memory(consumedbyonesensornode)\) indicates the memory used by a single sensor node. When the cost is lower, the method is said to be more efficient. * Impact on Accuracy: It is defined as the ratio of the number of data points that are accurately delivered to the base station. It is measured in terms of percentage (%). It is formulated as \[Accuracy=\left(\frac{\text{Number of data points accurately delivered}}{\text{Number of data points sent}}\right)\times 100\] (5) From (5), the Accuracy is determined. When the accuracy level is higher, the method is said to be more efficient. * Impact on Execution Time: It is defined as the product of the number of sensor nodes and the time consumed by one sensor node. It is measured in terms of milliseconds (ms). It is calculated as \[ET=\sum_{i=1}^{n}Sn_{i}\times\text{Time(consumed by one sensor node)}\] (6) From (6), the Execution Time \(ET\) is determined. \(Sn_{i}\) refers to each individual sensor node \(i\) in the network. \(n\) indicates the number of sensor nodes \(Sn_{i}\). \(Time(consumedbyonesensornode)\) indicates the time taken by a single sensor node to complete its tasks. When the execution time is less, the method is said to be more efficient. * Impact on Error Rate: It is defined as the ratio of the number of data points that are inaccurately delivered to the total number of data points sent. It is measured in terms of percentage (%). It is calculated as \[ER=\left(\frac{\text{Number of data points inaccurately delivered}}{\text{Number of data points sent}}\right)\times 100\] (7) From (7), the \(ER\) is the Error Rate computed. When the error rate is lower, the method is said to be more efficient. * Impact on Network Lifetime: It is measured as the ratio of the initial energy of the node to the energy consumption per transmission. It is mathematically computed as follows: \[NL=\frac{E_{I}}{E_{tr}}\] (8) From (8), \(NL\) denotes a Network Lifetime of sensor nodes. \(E_{I}\) represents the initial energy of the sensor nodes, i.e., 0.5 Joule taken for our simulation. \(E_{tr}\) indicates the energy consumption of a node per single transmission. It is measured in terms of seconds (S). When the network lifetime is shorter, the method is said to be more efficient. * Impact on Throughput: It refers to the size of gas data (i.e., data packets that are successfully delivered) within a given timeframe. Throughput is measured as follows: \[T=\frac{\text{SPT}}{\text{time (sec)}}\] (9) From (9), \(T\) symbolizes the Throughput. \(SPT\) denotes the size of the data packet successfully delivered in one second. The throughput is measured in kilobits per second (kbps).
