1) Providing data communication security through hybrid protocol for multiple WBANs working
at same time. This security protocol should consume low energy & also low memory space .
2) Prioritizing data/node based on critical physiological value sensed by sensors..(Data can be
classified as critical data & non-critical data & accordingly prioritization should be done). Need
to decide at which tier data prioritization should be done.
3) Handling node failures in all the 3 tiers as the WBAN consists of 3 tiers .
>> At sensor level/tier 1--Cluster head failure where data aggregation will be done,
>> tier-2-Personal server failure
>> tier 3-Medical server failure Related to this point also deciding suitable network structure,
topology & data routing mechanism ( algorithm) whether it should be ADHOC network or
Infrastructure based network along with pros, cons of each & justification for deciding the
chosen network structure.
