A Lightweight Security Scheme for Wireless Body Area Networks: Design, Energy Evaluation and Proposed Microprocessor Design

摘要: In order for wireless body area networks to meet widespread adoption, a number of security implications must be explored promote and maintain fundamental medical ethical principles social expectations. As result, integration functionality sensor nodes is required. Integrating node increases the size stored software program in memory, required time that sensor's microprocessor needs process data network traffic which exchanged among sensors. This overhead has dominant impact on energy dissipation strongly related lifetime sensor, critical aspect (WSN) technology. Strict definition functionality, complete hardware model (microprocessor radio), WBAN topology structure medium access control (MAC) frame are an accurate estimation introduces into WBAN. this work, we define lightweight scheme WBAN, estimate additional consumption based commercial available off-the-shelf components MAC frame. Furthermore, propose new microcontroller design reduce system. Experimental results comparisons with other works given.
