Abstract

Recently, sensor networks support solutions for various applications. These sensor networks have limitations of system resource. Therefore, there are a number of proposals to solve these problems. Those, however, do not consider security problem. In the sensor networks, the security is a critical issue since an entire resource of sensor nodes can be consumed by attackers. In this paper, we will consider security problems about the MAC protocol which extends lifetime of node using active signal that prevents receiving duplicate messages, and the routing algorithm which considers node's lifetime. Then we propose countermeasures that establish the trust relationship between neighboring sensor nodes, checks the bi-directionality each nodes, and authenticates node's information messages.
