It's no exaggeration to state that blockchain is pervasive in the healthcare industry. According to industry insiders, its application in healthcare has yet to achieve its full potential, but the implications might be substantial as it matures. This chapter presents the ongoing research trends, the existing issues and challenges, and presents future research opportunities to understand blockchain better. This chapter also throws light on the concepts of blockchain. This chapter also presents some examples of the uses of blockchain in healthcare. The authors hope that this chapter provides insight to the readers on the present and future research opportunities of blockchain in healthcare.

In order to enhance the lifetime of the Wireless Sensor Network, a two-level hierarchy of Cluster-heads is formed. At the initial level of the two-level hierarchy, a node with high residual energy and centrality is selected as the Cluster-head. Cluster-heads are elected for every cluster in the network by using the above said two descriptors. At the final level of the two-level hierarchy, a Chief Cluster-head is selected for the entire network. Out of the elected Cluster-heads in the network, the Cluster-head with high residual energy, with a low concentration and nearer to the base station is selected as the Chief Cluster-head. All the Cluster-heads of the clusters in the network will aggregate the data received from other sensor nodes in the clusters and send to the Chief Cluster-head. The Chief Cluster-head compresses the data ...

Similarly shortest path from source to destination is also important for routing. Several routing protocols for MANETs have been proposed. Most of the existing routing protocols are single routing path between source and destination nodes. This results in rapid depletion of battery power of the nodes that comprise the path between the source and destination nodes and on the other hand the devices in mobile ad-hoc network have limited power. The proposed protocol overcomes these drawbacks by following a hybrid approach to routing of data packets by establishing Energy efficient zone disjoint shortest multipaths between the source and destination zones by avoiding paths with nodes that have a shorter lifetime remaining, since the nodes‟ residual energy is important in determining the path to successfully complete data transfer without interruption and also avoiding paths with many hopes, which delays the delivery of packets. The pr...

Most of the current Web browsers still employ traditional caching policies that are not efficient in web caching. This research proposes a splitting browser cache to two caches, instant cache and durable cache. Initially, a web object is stored in instant cache, and the web objects that are visited more than the pre-specified threshold value will be moved to durable cache. Other objects are removed by Least Recently Used (LRU) algorithm as instant cache is full. More significantly, when the durable cache saturates, a fuzzy system is employed in classifying each object stored in durable cache into either cacheable or uncacheable object. The old uncacheable objects are candidate for removing from the durable cache. By implementing this mechanism, the cache pollution can be mitigated and the cache space can be utilized effectively. Experimental results have revealed that the proposed approach can improve the performance up to 14.8% and 17.9% in terms of hit ratio (HR) compared to LRU and Least Frequently Used (LFU). In terms of byte hit ratio (BHR), the performance is improved up to 2.57%, compared to LRU and LFU.

In addition, due to various conditions like limited radio range, physical obstacles or inclement weather, some nodes in the network might not be able to communicate with others. This could result in a disconnected network. In such situations, a typical network protocol might not yield good results. Message Ferrying is an approach which works around such problems. The message ferrying technique makes use of mobile nodes, called “ferries”, which are able to collect and transport data from one node to another. There are two approaches to deliver a message, Node-Initiated Message Ferrying (NIMF) and Ferry-Initiated Message Ferrying (FIMF). In NIMF approach a node will move towards known route of ferry if it has data to transmit or receive. The node comes close so that ferry will be in normal range of node. In FIME appro...

The nodes in a MANET have limited resources and restricted transmission range. The infrastructure of a MANET is not fixed but is easy and quick to setup. Application areas of MANETs include, but not limited to; emergency services, disaster recovery, environment monitoring, home networking, personal area networking, search and rescue operations, etc. The inherent nature of MANETs brings many operational limitations. This paper mainly discusses the operational limitations of MANETs, which raise various challenges in transforming it into the commercial world viable. These limitations include bandwidth constraints, energy constraints, storage limitations, mobility issues, variation in link capabilities, etc. This study starts with the evolution of the mobile ad hoc networks, later provides an insight into more pragmatic applications and finally on the operational limitations of MANETs. To make a transition of MANET to the commercial world viable, the operational limitations of MANETs need to overcome.

Since MANET's topology is highly dynamic, data items should be made available to the nodes that are required by them in a minimum distance. The nodes which initially store data may move far because of the dynamic topology and the nodes that are selected for relocation should be nearer to the nodes that are in need of them. Also the nodes which store the replicas may drain out in servicing excessive data access requests. This proposed scheme not only considers the minimum distance parameter, but also considers the vital parameters like storage availability, and residual energy parameters in selecting the node for relocation. The proposed scheme was implemented in NS2 and when compared to the no relocation scheme, our proposed scheme proved to be superior.
