Motivation Ad-hoc routing protocol can be classified into various categories such as : Ad-hoc routing protocol can be classified into various categories such as : Pro-active or Reactive Pro-active or Reactive Multicast Multicast Geographical Geographical Hierarchical Hierarchical Power-aware Power-aware Pro-active, or table driven protocols is traditional protocol used in wired networks but for wireless, cost of bandwidth to maintain fresh routing table is too high and reactive, or on-demand method is more popular in ad-hoc. This is a trade-off between bandwidth and packet latency. Pro-active, or table driven protocols is traditional protocol used in wired networks but for wireless, cost of bandwidth to maintain fresh routing table is too high and reactive, or on-demand method is more popular in ad-hoc. This is a trade-off between bandwidth and packet latency.

Motivation AODV, DSR, and OLSR are most popular protocols in ad-hoc routing. First two are reactive and OLSR is proactive. AODV, DSR, and OLSR are most popular protocols in ad-hoc routing. First two are reactive and OLSR is proactive. On this project, we will measure the performance of AODV, DSR and OLSR and compare them focusing on pro-activeness and re-activeness. On this project, we will measure the performance of AODV, DSR and OLSR and compare them focusing on pro-activeness and re-activeness.

Goals and Scope Goal Goal How does AODV, DSR, and OLSR perform? How does AODV, DSR, and OLSR perform? How Does pro-activeness and re-activeness influence their performance? How Does pro-activeness and re-activeness influence their performance? Scalability of AODV, DSR, and OLSR on increase of traffic and users. Scalability of AODV, DSR, and OLSR on increase of traffic and users.

Pro-active vs. On-demand Pro-active vs. On-demand Pro-active Routing (OLSR) Pro-active Routing (OLSR) Configure the routes toward any node before packet transmission Configure the routes toward any node before packet transmission Traditional method for Wired Network Traditional method for Wired Network On-Demand Routing (AODV, DSR) On-Demand Routing (AODV, DSR) Find the route just before packet transmission Find the route just before packet transmission Due to the high cost of wireless bandwidth Due to the high cost of wireless bandwidth Trade-off btw Bandwidth and Packet Latency!
