Abstract
Aiming at the limited resources and the security issues in wireless sensor networks, a routing approach is proposed. In this approach, the factors of reputation, remaining energy, and the distance to the destination are taken into considered while searching a routing path from an original sender node to the destination. A reputation-based mechanism is also proposed, and a node’s reputation depends on its behaviors. The malicious behaviors nodes will be punished and isolated, and the cooperative ones will be rewarded. Simulation results show that our proposed routing scheme can prolong the lifetime of the network and can offers a relatively high throughput than other routing protocols even when there are malicious nodes in the networks.

Wireless sensor networks (WSN) are gaining increasingly impact in our day to day lives
Due to the open nature of the wireless communication, the lack of infrastructure, and the hostile deployment environments, WSN are vulnerable to many types of attacks such as Sybil attacks, Wormhole attacks, Sinkhole attacks, Denial of Service (DoS) attacks, and Selective forwarding attacks et al One of the most dangerous attacks is Selective forwarding attacks, in which malicious nodes drop the packets transferring through them randomly and the packets may include sensitive data
We proposed a new routing approach to enforce the security of the network, and prolong its lifetime
Summary
Wireless sensor networks (WSN) are gaining increasingly impact in our day to day lives. As the malicious node may drop the packets deliberately, how to find a secure, energy-efficient routing becomes an important issue to be solved. We propose a new reputation-based game model for routing in WSN.
