One may simulate it in ns. If the code of LEACH is not there in ns, one needs to write one's own code.

Thanks sir for your reply. Castilia is my simulator and would like to simulate leach using this simulator. I have simulated other routing protocols such as gpsr using videos, however, could not find how to simulate leach.

I have implemented a new simulator using VC++ and used it for evaluating ANCH and LEACH algorithms. But for you, I might suggest Castalia which is a good simulator.

Thanks Mr Morteza for your reply.

I have implemented my own routing protocol which is based on LEACH and have simulated it using Castalia. I am very happy with Castalia, becuase it is almost 2 years I am using Castalia.

I am asking if some one simulate LEACH using Video Sensor application developoed by Prof. Pham. As shown in this link.

I have suceesfully installed the model and seen results about displying images for detected intrusions using GPSR. Hower, I need to see the same results using LEACH instead of GPSR.

Thanks again for your help.
