Topological design for wireless sensor networks for riverbank based on geographical characteristics

This paper investigates the mechanism for nodes placement along the riverbanks. The proposed algorithm intends to minimize the total number of sensor nodes with several constraints such as network connectivity and network reliability. This algorithm also aims to achieve the maximum transmission distance along the riverbank which will guarantee the river sensored information coverage, connectivity and reliability. The proposed algorithm will be adjustable to the geographical profiles of the river. Simulation results are obtained from four different river profiles. The proposed algorithm performs well as it could reduce the number of sensor nodes needed for sensoring.
