Energy efficient modified SPIN protocol with high security in Wireless Sensor Networks using TOSSIM

Sensor nodes are very important attribute in Wireless Sensor Networks (WSNs), due to communication over wireless links but it has some constrains i.e. limited transmission range, processing, storage capacity and energy. To get secure communication under these circumstances SPIN protocol incorporated data security for transferring data safely to the destination. To overcome the problem of SPIN protocol such as blind forward and data inaccessible, in this paper, we propose and design modified SPIN routing protocol to save energy and give secure transmission to minimize overhead with data delivery guarantees. Our goal is to find an optimal path and efficient implementation of protocol for data negotiation, set up route and finally transfer data to specific nodes. Our novelty in this paper is more secure data transmission than SPIN. The simulations have been carried out by new operating system TOSSIM to compare data transfer rate with communication security and lifetime of networks.
