Network reliability represents a probability that a network node or network element can be functioned satisfactorily for a given time interval under particular operations. The four key factors here are probability, satisfactory performance, time and specified operating conditions [1,2]. The need for network reliability is given below [2]:

Probability is used for the measure of the performance. When the devices function under similar conditions, failures may take place at different points in time; the occurrence of the failures can be expressed in terms of probability theory.

The network performance shows accomplishment of the system having a combination of qualitative and quantitative factors. These are performance parameters such as bit error rate (BER), throughput, and delay.

Time is an important factor for the evaluation of reliability measurement showing the probability of a system being operational.

The operating conditions are geographical location of the system, weather extremes in which the system is exposed (e.g., temperature, wind, humidity, vibration, shock and potential damage).
