PROBLEMOBJECTIVES AND PROPOSED METHODOLOGY
3.1Problem Objectives
Security is one of the most imperative aspects of any system. People have different perspective regarding security and hence it defined in many ways. In general, security is a concept similar to safety of the system as a whole. Now, the communication in sensor network applications in healthcare are mostly wireless in nature. This may result in various security threats to these systems. These are the security issues cloud pose serious problems to the wireless sensor devices. In this section, that describe the key security requirements in IoT based healthcare system using BAN. To simultaneously achieve system efficiency and robustness of transmission within public IoT-based communication networks, that utilize robust crypto-primitives to construct two communication mechanisms for ensuring transmission confidentiality and providing entity authentication among smart objects, the local processing unit and the backend BSN server.

3.2.1 Protocol and System Description:
Phase I: Registration Phase

Setup phase
#No. of nodes N
# BS can transmit i levels; i ?1
1. For each level i, message transmitted by BS
2. If (Nodes does not assign previous level and hear new message or BS transmit level i=1)
3. Assign level i
4. End if
5. End for
6. BS broadcast hello message, which contains the information of upper limit and lower limit of each level.
7. Each node calculates the distance from the BS based on received signal strength

Phase II: Authentication Protocol:
This phase completes goals of mutual validation among the LPU, and the server by stabilising anonymity, and secure localization. This phase involves of the resulting steps:

Here, LAIl is the situation area identifier of the base station, which depicts the physical involving between the LPU and the base situation of a portable web and it will be used to afford protected localization.
Note that, in situation of loss of body, the LPU needs to choose one of the unexploited pair of (sid j , kemj ) and after, assigns the sid j as AIDL i.e. AIDL = sid j and then assigns kemj as K ls. In that case, LPU will not send any track classification number T r Seq in MA1.

The illustrative explanation of the practice is Note that, in our BSN-Care organisation when a sensor needsto send some BSN data to LPU. In that case, assume that both the sensor and the LPU can connect each other over the password-based straight bluetooth authentication course.
4.2.2 Firefly Framework
Firefly is an insect that habitually produces short and pulsing flashes that twisted by a process of bioluminescence. The role of the alternating light is to charm cronies (communication) or attract potential prey and as a protective warning toward the predator. Thus, the power of light is the feature of the other fireflies to move near the other firefly. The light concentration is varied at the detachment from the eyes of the beholder. It is safe to say that the light power is decreased as the detachment rise.
The light concentration also the inspiration of the air absorb by the settings, thus the intensity converts less appealing as the detachment increase. Firefly process was tailed three venerate rules, 1) Fireflies are engrossed toward each other nevertheless of gender. 2) The appeal of the fireflies is correlative with the brilliance of the fireflies, thus the less gorgeous firefly will move advancing to the more beautiful firefly. 3) The intensity of fireflies is depends on the neutral role.
The first step in the system is the initialization of the population of N fireflies where each firefly characterises a entrant solution. Population size (N) characterises the figure of explanations or the size of the search space. An unbiased function is connected with the intensity of the firefly and is unswervingly relational to the brilliance.
3.2.3 Firefly algorithm
The firefly algorithm (FA) is a meta empirical process, inspired by the alternating behavior of fireflies. The main purpose for a firefly’s flash is to act as a indication organisation to charm other fireflies.
a. All fireflies are unisexual, so that one firefly will be concerned to all extra fireflies nevertheless of their sex.
b. Draw is proportional to their glare, and for any two fireflies, the less happy one will be concerned by the livelier one.
c. If there are no fireflies livelier than a given firefly, it will move haphazardly.
The intensity should be allied with the neutral function. Accept that there occurs a flight of n agents (fireflies) and Xi characterizes a explanation for a firefly i, whereas f (Xi) denotes its fitness value . Here the intensity I of a firefly is particular to reflect its current position x of its fitness value f (x).
Ii = f (Xi), 1 ? i ? n. (1)
Firefly appeal is proportional to the light concentration seen by together fireflies. Each firefly has its distinguishing appeal ? which infers how strong it fascinates other followers of the swarm. Yet, the appeal ? is relative, it will contrast with the distance r i j amongst two fireflies i and j at settings xi and xj singly, is given as
rij = ?xi? xj?. (2)
The degree of appeal of a firefly is resolute by
?(r) = ?0e?? r^2 (3)
Where, ?0 is the appeal at r = 0 and ? is the light raptness amount at the source. The undertaking of a firefly i at position xi attracted to added more beautiful (brighter) firefly j at location xj is gritty by
xi(t + 1) = xi(t) + ?0e?? r^2(xj? xi). (4)
3.2.4 Pseudo code for Firefly Algorithm
1. Neutral function of f(x),
2. Generate initial population of fireflies;
3. Convey light intensity I;
4. Define absorption coefficient ?;
5. While (t Ii), move firefly i towards j;
6. For i = 1 to n (all n fireflies);
7. For j=1 to n (all n fireflies)
8. If (Ij> Ii), move firefly i towards j;
9. end if
10. Evaluate new solutions and update light intensity;
11. End for j;
12. End for i;
13. Overgrown the fireflies and find the current best;
14. End while;
15. Post course results and visualization;
16. End procedure
