Bloom Filter Supporting Distributed Policy-Based Management in Wireless Sensor Networks

Wireless Sensor Networks (WSN) are particularly special due to many characteristics, such as a working environment that makes maintenance and support a challenge; and hardware resources, particularly memory, processing and battery power, that make it capable of handling only limited software. Consequently, the administration of WSN is becoming a challenge. To overcome these limitations we proposed Distributed Policy-Based Management (DBPM) framework. Our proposed framework is expected to conceal the complexity of administrating policies operations from the users by simplifying the deployment processes. Bloom Filter is an elegant data structure that answers the membership inquiry with no false negative and manageable false positive. In this paper we propose utilizing Bloom Filter in Distributed Policy-Based Management (DPBM) environment in WSN to confirm the existence of any policy within the WSN, which will reduce the traffic within the network as well as preserve the sensor node energy.
