Abstract

Wireless mobile ad-hoc networks (MANeT) provide hop-by-hop routes (e.g. 2.4 GHz ZigBee) along shortest paths to reach the controller from many sensor sources. An outdoor line-of-sight RF link can cover over 100 metres. However, inside a multi-storey building, the range often drops to less than 10 metres or is even completely blocked by floors and ceilings. The power-line network of a building can become an auxiliary signal transmission medium which would guide the weak signals from sensors at different locations to the base controller several storeys away.
