Available Bandwidth Estimation in Network-Aware Applications for Wireless Campus e-Learning System

Algorithm 1

WBest algorithm.

(1) Send n packet pairs to client

(2) 𝐶_𝑒←median(𝐶_𝑖),𝑖=1,…,𝑛

(3) Send m packet train at rate 𝐶_𝑒 to Client

(4) 𝑅←𝐿/mean(𝑇_𝑖),(𝑖=1,…,𝑚−1)

(5) If 𝑅≥𝐶_𝑒/2 thenAB⇐𝐶_𝑒[2−𝐶_𝑒/𝑅]

(6) Else AB⇐0

(7) 𝑝 ⇐ packet loss rate in train

(8) if 𝑝>0 thenAB⇐AB×(1– 𝑝)
