Efficient Data Delivery over Address-Free Wireless Sensor Networks

Addressing plays a vital role in traditional packet networks but it introduces too much overhead, wasting precious resources, for data-centric and resource-constrained wireless sensor networks. As a result, it is desirable to design networks that are without the addressing function, termed as addressfree wireless sensor networks. However, current data delivery mechanisms proposed for wireless sensor networks depend highly on addressing since addresses either convey topological information that is exploited to find routes or are used as unique identifiers to identify sensors during data delivery. In this paper, we propose a data delivery protocol for address-free wireless sensor networks. This protocol does not exploit sensor addresses or even their identifiers in any aspects. Our analytical and simulation results demonstrate its effectiveness and transmission efficiency.
