Abstract: This project deals with simulation and here the simulator used is Network Simulator. And sensor network are used to sense the collision of packets. Here we also use number of nodes to transmit packet. This simulation project deals with arrangements of packets, and transmitting those packets from source to destination. Here we transmit the packet in two different medium that is air medium and water medium. During the transmission of packets from source to destination, there packets may collied with each other. To avoid this collision we use two transmission schemes namely Collision Free Scheme (CFS) and Collision Tolerant Scheme(CTS).
Keywords: Dijisktra’s algorithm; Poisson distribution technique; Number of nodes; sensor networks.
