The Realization And Optimization Of Link Queue Algorithm And AODV Protocol

Nowadays it is the epoch of Internet that makes an increasingly more significant effort in the modern society. People`s dependent and desire for net raises everyday, And people request for more enhanced serve. It is important to study network knowledge for students of computer science major. It is obviously hard to understand the abstract network protocol in the network class. The program developed by us and described in the thesis supply teachers with the convenient teaching methods and students with visual simulated process. By then we revised the AODV wireless protocol, enhancing the managing performance to nodes` energy.We firstly introduced the character and means of nowadays network teaching and put forward their drawbacks. We proposed visual and controllable teaching software based on network simulator. To implement the design, we also presented TCP and AODV protocol respectively. We analyzed the slow-start algorithm in TCP protocol.We secondly introduced how to set thresh value in slow-start and how to set some parameters in AODV protocol. We implemented how to set parameter in our TCP and AODV protocol visual and controllable teaching programs using the script template and TK components to build dialogue. We compared the changing of TCP slow-start thresh value and congestion windows in the different link queue algorithms.Eventually we proposed an enhanced AODV protocol based nodes` energy. It uses a thresh value to check whether the nodes` energy is too week to forward the packet and if not, sends RRER to find a new path. It also compares the nodes` energy in the RREP to pick out the nodes that does not fulfill the standard, and also sends RRER to find another path. Thus, we can avoid the unnecessary loss so as to nodes` insufficient energy. We compare the enhaned AODV with original AODV in the circumstance of 50 nodes by network simulator.
