Abstract: “When a Body Sensor Network (BSN) that is linked to the backbone via a wireless network interface roams from one coverage zone to another then in between wireless-body-area-networks (WBAN) interference created, which can cause serious throughput degradation and energy waste. When a wireless body area network become mobile then problem arises of inter process interference A necessity appears for efficient WBAN monitoring information extraction, high spatial reuse, dynamically fine tuning the monitoring process to suit the data quality, provision for allowing the translation of high-level requirements of medical officers to low-level sensor reconfiguration. Issues related to security and possible solutions must be taken in the research. Study brings out that the current proposed solutions in security are still having limitations needing further research. This paper proposes an optimized BSN handover strategy, RASS (Real-time Accurate and Scalable System) and VMISO(Virtual Multiple Input S”
