The materialization of sensor networks as one of the dominant technology trends in the coming decades has posed numerous unique challenges to researchers. These networks are likely to be composed of hundreds, and potentially thousands of tiny sensor nodes, functioning separately, and in many cases, without access to renewable energy resources. Cost constraints and the need for omnipresent, invisible deployments will result in small sized, resource-constrained sensor nodes. While the set of challenges in sensor networks are diverse, the authors focus on security of wireless sensor network in this paper. They propose some of the security goal for wireless sensor network.
