Performance Comparison of Wireless Sensor Networks for Different Speeds of Multi Mobile Sensor Nodes

Wireless Sensor Networks (WSNs) have become a hot research theme in academia as well as in industry in recent years due to its wide range of applications ranging from medical research to military. In this paper, we study the effect of IEEE 802.15.4 MAC standard on the performance of AODV protocol for WSNs environment with mobile sensors. The WSNs should allow a systematic deployment of sensor nodes including mobility among the sensor nodes. The disseminated data from the sensor nodes are gathered at the sink node. Data dissemination is the major source for energy consumption in WSNs. We consider as evaluation parameter good put, depletion and Routing Efficiency (RE) to evaluate the performance of WSNs considering different speeds of mobile sensor nodes. The simulation results show that when the network is not congested, the good put is higher for higher values of the speed. The depletion is almost the same for low values of Tr. For high values of Tr (more than 850 pps), the RE has better performance when the mobile sensor nodes move at 10m/s.
