It is largely due to stringent requirements for fully distributed coordination among sensor nodes leading to the wasteful use of available address space. As there is a growing need for a large-scale WSN it will be extremely challenging to support more than thousands of nodes using existing standard bodies. Moreover it is highly unlikely to change the existing standards primarily due to backward compatibility issue. In response we propose an elegant addressing scheme and its routing algorithm. While maintaining the existing address scheme it tackles the wastage problem and achieves no additional memory storage during a routing. We also present an adaptive routing algorithm for location-aware applications using our addressing scheme. Through a series of simulations we prove that our approach can achieve two times lesser routing time than the existing standard in a ZigBee network. Copyright 2008 Soojung Hur et al.
