WSN Performance Evaluation

Overview: 

The variety of applications of wireless sensor networks (WSN) has attracted the attention of both public and research communities at large in the recent years. A lot of research is being done in this field to explore the still uncovered potential of using WSNs. However, the limited available resources on a sensor node make it even more challenging to meet the requirements of an application. Mostly sensor nodes are required to provide data in a timely manner. Nonetheless, the performance of data propagated over a wireless medium depends on many facts, some of which are beyond control.

 Some of these factors are environmental, while others depend upon parameters settings of the sensor node such as modulation scheme, transmission power, and frequency channel used.  Therefore, a research to explore the relationship between different parameters and its effect on network performance focusing on WSN is the major goal of this thesis. The hybrid testbed called, DES-Testbed, is deployed by our group will be used to perform extensive experimentation, gathering data and analyzing the results to reach onto concrete conclusions. The stationary sensor nodes used are the MSB-A2 nodes by ScatterWeb.

Objectives: 

• To understand DES-Testbed and get familiar with MSB-A2 node
• To design and perform different  experiments on DES-Testbed
• Gather and evaluate results to relate the relationship between different parameters and network performance in WSN
