Title: "SIDA: Self-Organized ID Assignment in Wireless Sensor Networks"

Abstract

Having an ID being unique within the application domain for each sensor
node is the basic assumption in many WSN applications. In traditional
assignments, fixed-length ID schemes, which are severely limited by
scalability, flexibility and energy efficiency, are adopted. To solve
these problems, a novel variable-length ID scheme is proposed that allows
different nodes to have different ID lengths. To realize this idea, we
propose a fully localized ID assignment algorithm called Self-organized ID
Assignment (SIDA). SIDA presents great potential on scalability,
flexibility and energy efficiency by enabling online ID assignment and
various optimizations according to different communication paradigms.
Analytical and simulation results show that SIDA has a comparable static
ID length while the accumulated communication overhead for multi-hop
transmissions can be saved by 20%; the control overhead of the new
deployment assignment can be reduced to about 30% compared with
fixed-length schemes.
