Unformatted text preview: Implementation of LQSR in NS-2 October 26, 2006 1 Objective Implement ETX link quality measurement technique and modify DSR to ac- count for it. 2 Project steps • Read and understand DSR operation and ETX Refer to DSR paper by David B. Johnson  Refer to Decouto paper  Refer to details of ETX protocol at cuwireless • Install NS-2 • Understand NS-2 code for DSR FAQs that might be helpful while understanding DSR in NS2  NS-2 is under ns-allinone-2.30/ns-2.30/dsr/ directory • Implement ETX Keep it modular so that any routing protocol can use ETX with minimum changes. Refer to the paper “A High-Throughput Path Metric for Multi-Hop Wireless Routing” by De Couto et al. • Use ETX in DSR 3 Implementing ETX in NS-2 The prerequisite for this section is an understanding of the paper . 1 • Create a new protocol in NS-2. Let us call this “ETX protocol”. The purpose of this protocol is to measure the link quality. This protocol is responsible for sending and receiving the measurement packets for a node. A sample tutorial to add a new protocol (at routing layer) in NS-2 can be found at reference . Google for more references....
