ABSTRACT
The emergence 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 autonomously, and in many cases, without access to renewable energy resources. Cost constraints and the need for ubiquitous, invisible deployments will result in small sized, resource-constrained sensor nodes. While the set of challenges in sensor networks are diverse, we focus on security of Wireless Sensor Network in this paper. We propose some of the security goal for Wireless Sensor Network. Further, security being vital to the acceptance and use of sensor networks for many applications; we have made an in depth threat analysis of Wireless Sensor Network. We also propose some countermeasures against these threats in Wireless Sensor Network. Wearable wireless medical body sensor networks provide a new way of continuous monitoring and analysis of physiological parameters. Reliable transmission of real-time vital signs is a basic requirement for the design of the system. This paper explores multi-homing to increase data reliability for body sensor networks. It proposes a multi-homed body sensors framework and investigates handover strategies during sensor nodes movement.
