Secure data transmission routing protocol for multicasting

As sensor network edge closer towards wide-spread deployment, security issues become a central concern. So far, more research has focused on making sensor networks for feasible and useful, but not concentrated on security. Recently, technological advancement in the field of nanotechnology have increased the computation power of the wireless nodes while adhering to the energy constraints. This made use of Wireless Sensor Networks (WSNs), more widespread, used in applications such as area monitoring, industrial monitoring, vehicle detection or military monitoring. SPIN, Sensor Protocol for Information via Negotiation, is one of the widely used efficient routing protocol in WSNs that completely ignores the security aspect. SPIN overcome the performance deficiencies of conventional protocols by implementing data negotiation, nodes communicating with each other about the data that they have send already and also the data they still need to obtain, and resource adaption, that is, nodes monitor and adapting to changes in their own energy resources. This project mainly propose an alternate routing protocol which routes the data similar to SPIN, but with additional security features. The energy performance characteristics, large number of nodes and percentage of malicious nodes are compared with SPIN and MS-SPIN in NS2.
