thanks guys. is this possible to provide some fixed hopping node or routng path in mobile network. and what happened if the node which is out of range want to send packets through base station. let n3 out of range bs is base station and signal reached to n3 from bs through n2. but if n2 want to communicate n1 any other node which path signal follow now. 1. signal goes to bs through n2 and then from bs to b1 or 2. signal goes to n1 from n3 directly if its in range or 3. signal goes to n1 from n3 through hopping at node n2. can u please tell me how to implement patch for routing. thanks guy for help. One way to introduce multihop is to increase the distance between each node to be 250m, as the default trasnmission range for each node is set to be 250m, alternatively you can decrease the transmit power for each node, thus if you have 3 nodes (a,b & c), and you want to transmit from a to c, then if you set less transmit power e.g. 40m for each node. You will observe message reaching c via b. Alternatively you can introduce NOAH routing protocol, this allows you to create a multihop scenario within the requred nodes (you will need to download the patch and install NOAH. I hope this helps Kind regards Qasim Raza Iqbal PhD Candidate, ACNRG Lab N504, Office N505 Adaptive Communications Networks Research Group, School of Engineering And Applied Science Aston University Birmingham B4 7ET United Kingdom http://www.ee.aston.ac.uk/research/acrg/index.html Make sure that transmission range is less than inter-node distance. You can see the archives on how to set the transmission range. In the process, you will also require to use the program: ns-2.30/indep-utils/propagation/threshold Tarun On 8 Feb 2007 16:46:17 -0000, harpreet <[EMAIL PROTECTED]> wrote: > > > Hi > I am a beginner in NS.
