Wireless Sensor Networks (WSNs) have many capabilities like wireless communications, sensing and computation. Due to these advanced features they perform critical tasks in many application areas such as environment monitoring, health applications, rescue operations and many more. One of the major challenges in WSN is efficient data transmission and to achieve this many energy efficient routing protocols have been proposed. Flooding is one of the major communication techniques in this aspect. However it suffers from many problems like implosion, overlap and resource blindness [25]. These problems can be addressed using data-centric data transmission approach. One of the routing protocols employing this approach is Sensor Protocols for Information via Negotiation (SPIN) protocol [2] which uses meta-data to eliminate the transmission of redundant data throughout the network. There are four different SPIN protocols namely SPIN-PP for point to point transmission, SPIN-EC which adds energy conservation heuristic [7], SPIN-BC which is used for broadcast transmission media and SPIN-RL which is a reliable version of SPIN-BC. In this paper a comparative study has been done among flooding and the SPIN protocols.
