4.4.1 Node Density Effect
In order to see how the energy consumption is changing with a specific node density under our topology
some different scenarios have been used with a maximum of 20 ,50 and 100 nodes, respectively. A squared
2000m by 2000m area is used as the simulation area. The choice of random moving nodes number is based
on the fact that these settings have been used at most studies .Most of them are using parameters close to
these one. These parameters have been set to be close to the reality and to be not too computer intensive.
We choose the RWP mobility model as our node mobility model. The setdest tool is used to generate the
movement scene. It take over one hour to generate the 100 nodes movement scene, the 200 nodes scene take
us over nigh hours!
The common three routing protocols: AODV,DSDV,DSR are used as our base routing protocol. The
energy consumption are analyzed and showed below:
Each node can transmit up to 250m. A simulation time of 900s is used, which is long enough to evaluate
our energy model.
