A sensor deployment strategy in bus-based hybrid ad-hoc networks

Abstract

Sensor deployment is one of the challenging issues in Wireless Sensor Networks (WSNs). Traditionally, sensors are deployed for sensing and transmitting data to Base Station (BS) for further data processing in cities. However, instead of sensor independently allocated, we apply the existing transportation infrastructure - Bus-based Ad hoc Network (BANETs) to assist the sensing and transmission of the WSNs. A novel hybrid scheme is derived to this hybrid network. Then we utilize the practical simulator ONE [1] to analyse our scheme and simulation indicates that the scheme can significantly reduce the number of sensors to be deployed, and the information collected from the city could reach the BS within a fixed time.
