Abstract

In many environments where communications infrastructure already exists, e.g. factories and hospitals, sensor networks applications are becoming increasingly interesting. We present our ongoing work aimed at developing a network architecture using such existing infrastructure as proxy support for sensor networks. The proposed topology is asymmetric in its communication, ie the proxy can reach its sensor nodes in one hop but there is no guarantee that the sensor nodes reach the proxy directly. Thus we propose to divide the topology hierarchically. Too handle sensor nodes with different demands and to save energy at the sensor nodes we propose to schedule the sensor nodes with time-division multiplexed access (TDMA). We outline a proposed network architecture and point out important research issues that must be addressed. One of the main purpose of this paper is to solicit feedback on our proposed network architecture.
