Abstract

 Wireless sensor network is collection of one or more homogeneous or heterogeneous sensor nodes which sense some events and inform sink for that by sending that data towards it to perform some action. Data transmission is the most effective factor in sensor network that directly regret energy of sensor node but though energy of sensor node is very crucial one need to save that energy by means of minimizing redundancy and retransmission of data. Till the day many routing protocols are introduced to route data efficiently in order to improve network life time but all protocols have some deficiency. One of the most popular data centric dissemination protocols is Sensor Protocol for Information via Negotiation (SPIN). It efficiently disseminates data among other nodes in the network. This protocol uses meta-data for negotiation and eliminates the transmission of the outmoded data throughout the network. This paper introduced improved SPIN which is further enhancement of SPIN protocol.
