On the connectivity of nodes in wireless ad hoc and sensor net

摘要

The transmission range of the nodes in ad hoc networks affects the connectivity and routing overhead. Therefore in the process of selecting the transmission range, knowledge about the connectivity of the network is crucial. Sensor network is considered as n node that are randomly located in some region with known dimensions. We create a model for the relationship between the number of nodes (n) and the transmission range so that the resulting network topology is connected with high probability. We utilize NS-2 to investigate the effect of transmission range, number of nodes and dimensions of the network on connectivity
