Blockchain and the healthcare sector have a serious concern with context to scalability, which has a challenge of converting arbitrary values to fixed values. The transfer of arbitrary data coming from diverse resources has another point of concern in the blockchain. In this paper, the author proposed a model that will receive data from diverse sources and will convert it to a fixed type of value. The paper also proposes an access control scheme with various permission and consensus level protocols which will allow a reduction in block size with respect to scalability. The consensus level will allow access to the individual or a group of users and the permission level with respect to each block via considering the access granted to nodes of the blockchain. The addition of various permission and consensus levels will allow only a restricted type of data to pass the model. Once the data is verified and approved by various levels, then the data is all set to be part of the blockchain. The paper introduces a model where the time taken to create a new hash is 0.15625 microseconds. A total number of 64 transactions taken from the data set where the throughput is calculated for individual access are considered. After applying the formula, the calculated throughput is 32.5 microseconds. By the lighter block size data can be made available to the patients. The research is for the patients so they can keep track of their medical history and the deaths due to overdose of the medicines can be reduced.

Mobile Internet Protocol version 4, in which the main problem is triangle routing. Mobile node deliver packets to a corresponding node directly but when corresponding node sends packet to the mobile node packet comes to foreign agent via home agent then it comes to mobile node. This asymmetry is called triangle routing. It leads to many problems, like load on the network and delay in delivering packets. The next generation IPv6 is designed to overcome this kind of problem (triangle routing). MIPv6 support host moves from one access point to another access point. To solve the triangle routing problem different route optimization schemes are used which exclude the inefficient routing paths by creating the shortest routing path. These are Liebsch’s Route optimization scheme, Light Weight Route optimization scheme & enhanced light weight route optimization scheme. In this paper I have consider only Light Weight Route optimization scheme & enhanced light weight route optimization scheme. I have taken Throughput and Packet delivery fraction, end to end delay & round trip time .Performance metrics to compare these two schemes by using NS-2 simulations. Throughput is the rate of communications per unit time. Packet delivery fraction (PDF) is the ratio of the data packets delivered to the destinations to those generated by the CBR sources. End to end delay includes all possible delays caused by buffering, re transmission delay & propagation & transfer times of data packets. Round-trip time is the time required for a signal pulse or packet to travel from a specific source to a specific destination and back again. By using these parameters I have found that enhanced light weight route optimization scheme performance is better than Light Weight Route optimization scheme.
