SPIN implementation in TinyOS environment using nesC

In this paper we present the simulation result of Sensor Protocol for Information via Negotiation (SPIN), a wireless sensor routing protocol, using TinyOS and nesC. TinyOS is a widely used operating system for modern wireless sensors, as its modular system is flexible and powerful. But programming with TinyOS can be challenging because it requires a new language, nesC. SPIN protocol is a data-centric routing protocol for Wireless Sensor Network (WSN). SPIN fits under event-driven delivery model. For implementing SPIN we divide the protocol into three phases. These are Initialization phase, DataCollection phase and Negotiation phase. The protocol is simulated in TOSSIM simulator which is an integral part of nesC.
