| 500 ## - GENERAL NOTE | |
| General note | Medium Access Control (MAC) and Physical (PHY) layer are the adjacent layers of<br/>the standard communication architecture. Therefore, they have strong coupling with<br/>each other and changes at the PHY layer do effect on the performance of the MAC<br/>layer. However, researchers quite often ignore the effect of PHY layer on the MAC<br/>layer, particularly while working with simulation. Being the wireless networks,<br/>Wireless Sensor Networks (WSNs) need to deal with the common issues such as<br/>interference, fading, attenuation and other bandwidth related concerns. Moreover,<br/>WSNs have very limited resources, particularly energy, that makes the inter-<br/>dependence of MAC and PHY layer even important. Ignoring this fact may lead to<br/>considerable imprecisions in the model predictions, mainly for wireless protocols.<br/>This thesis work aims to analyze the effect of PHY layer on the well-known BMAC<br/>protocol. Extensive experiments were carried out on OMNeT++ simulation platform<br/>to examine the performance of BMAC protocol with varying parameters at the PHY<br/>layers such as duty cycle, transmission power, radio sensitivity, path loss and<br/>propagation models. The evaluated metrics include energy consumption, data packet<br/>transmission & reception, data forwarding and preamble transmission & reception.<br/>The simulation results suggest that the smaller duty cycle value is suitable for the<br/>packet transmission and reception; moderate values of path loss coefficient are<br/>suitable for practical scenarios and model prediction. Similarly, smaller transmission<br/>power is suitable with increased number of hops only and better sensitivity level<br/>could extend the possible range ofa network that could solve coverage problems ofa<br/>WSN. This research study may help network designer in choosing an optimal value<br/>of the mentioned parameters for an application-specific scenario.<br/> |
