Optimized SPIN in Wireless Sensor Network

The popularity of Wireless Sensor Network (WSN) has increased tremendously in recent times. WSN has the potential to connect the physical world with the virtual world by forming a network of sensor nodes. In a sensor network the sensor nodes sense the data within their sensing range. Each node has limited energy which is used in transmitting and receiving the data thus energy preservation is most important for the survival of sensor networks for longer period time. Many routing protocols in WSN are used for the same purpose. In WSN, SPIN is a data centric routing protocol which efficiently propagates information among sensor nodes in an energy constrained mode. SPIN uses metadata negotiation to eliminate the redundant data. In this paper we proposed a mechanism to Optimize the SPIN Routing Protocol. The main objective of this paper is to use the metadata information while advertising, to reduce the energy consumption by the nodes in transmitting and receiving the data. We have implemented Basic SPIN and proposed Optimized SPIN protocols using MATLAB. After implementation we found that in Optimized SPIN, the number of dead nodes are 50% lesser than the existing SPIN protocol.
