Security for Wireless Sensor Network with Spin Protocol

Kunal M Pattani, Palak J Chauhan

In the recent past, Wireless Sensor Networks have been introduced to use in many application. Wireless Sensor Networks provides a way of information sensing, processing, communicating and transfer of information. To designs the networks, the factors needed to be considered are the coverage area, mobility, power consumptions, communication capabilities, etc. Wireless Sensor Networks have limited energy has hence efficient of protocol has a significant impact on network’s lifetime. Security is a main concern everything, whether it is for Wired based networks or wireless based networks. Security is a fundamental requirement of Wireless Sensor Networks. Security in Wireless Sensor Network plays an important role in node communication. For Wireless Sensor Networks has lots of security protocol available but some have limitations. SPIN (Sensor Protocol for Information via Negotiation) has contained three messages which have given security and energy efficiency to Wireless Sensor Network. SPIN protocol is based on data centric approach which efficiently propagates information between sensor nodes in energy constrained mode. SPIN protocol solves the problem of flooding and gossiping. In this documentation we had implement SPIN protocol in NS2 and energy efficient for nodes. We have implement SPIN protocol in Network Simulator. After implementation of SPIN protocol, we had optimized SPIN-I which has given sufficient energy of three stages
