| Resumo: | Wireless Sensor Networks (WSNs) have become increasingly common and studies on
them have increased a lot. This type of network is generally formed by many sensor nodes
that make testing hard in real environments. The network simulators, as the Network Simulator
2 (NS-2), have been adopted to evaluate WSN, however, this type of simulation in
the NS-2 may not be an easy task for users. Thus, tools were developed to provide simulation
facilities on the NS-2, such as WINSS (Wireless Network Sensor Simulator). WINSS
is a solution for the design and tests of simulations of WSNs in accordance to the IEEE
802.15.4 standard on NS-2. Due to the limitations of the original version of WINSS, this
work aims to extend the features of this tool, adding to it the possibility of working with:
node mobility, network faults, beacon-enabled and non beacon-enabled mode, among
other functionality. The WINSS generates simulation scripts (TCL scripts) and allows
the configuration of important aspects such as energy model, mobile nodes model, radio
propagation model and network fault model. It provides an integrated environment with
NAM, XGRAPH and Gnuplot, tools that complement the NS-2, and generates results,
like throughput, delay, packets loss, packets received and energy consumption. |
