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) 𝐢 𝑒 ← m e d i a n ( 𝐢 𝑖 ) , 𝑖 = 1 , … , 𝑛
(3) Send m packet train at rate 𝐢 𝑒 to Client
(4) 𝑅 ← 𝐿 / m e a n ( 𝑇 𝑖 ) , ( 𝑖 = 1 , … , π‘š βˆ’ 1 )
(5) If 𝑅 β‰₯ 𝐢 𝑒 / 2 then A B ⇐ 𝐢 𝑒 [ 2 βˆ’ 𝐢 𝑒 / 𝑅 ]
(6) Else A B ⇐ 0
(7) 𝑝 ⇐ packet loss rate in train
(8) if 𝑝 > 0 then A B ⇐ A B Γ— ( 1 – 𝑝 )
