Round Trip Delay Time as a Linear Function of Distance Between the Sensor Nodes in Wireless Sensor Network
In a dense wireless sensor networks with portable sensor nodes identification of sensor node location, distance of particular sensor node from some reference node and fault detection are the great challenging issues. Round Trip Delay (RTD) time measurement technique is an easy way to obtain the information regarding above issues in WSN. But round trip delay measurement is affected by various parameters of wireless sensor network. As the sensor nodes are placed randomly in network, sensor node distance has more impact on this time measurement. So it is necessary to study the relationship between the round trip delay time and Sensor node distance.
