A novel anomaly behavior detection scheme for mobile ad hoc networks

To sustain the security services in a Mobile Ad Hoc Networks (MANET), applications in terms of confidentially, authentication, integrity, authorization, key management, and abnormal behavior detection/anomaly detection are significant. The implementation of a sophisticated security mechanism requires a large number of network resources that degrade network performance. In addition, routing protocols designed for MANETs should be energy efficient in order to maximize network performance. In line with this view, this work proposes a new hybrid method called the data-driven zone-based routing protocol (DD-ZRP) for resource-constrained MANETs that incorporate anomaly detection schemes for security and energy awareness using Network Simulator 3. Most of the existing schemes use constant threshold values, which leads to false positive issues in the network. DD-ZRP uses a dynamic threshold to detect anomalies in MANETs. The simulation results show an improved detection ratio and performance for DD-ZRP over existing schemes; the method is substantially better than the prevailing protocols with respect to anomaly detection for security enhancement, energy efficiency, and optimization of available resources

Management of haemangioma neck using sclerosing agent- a case report

Although hemangiomas are common in infancy and childhood, they are probably developmental abnormalities rather than true neoplasms. In present case we have treated a child aged 10 years with haemangioma of the right side of the Neck. After thorough investigation we posted this for intralesional infiltration of Sclerosing agent (Inj. Polidocanol 3%) in 1:3 dilution with normal saline. Approximately 2 ml Inj. Polidocanol diluted with saline was injected into the lesion. And the same procedure was repeated in three sittings after one week interval. The size and vascularity was reduced dramatically after single procedure. Patient was followed up after one and two months interval. There was no sign of any recurrence. This Procedure was chosen as it is cosmetically more acceptable, can be used for the haemangiomas at inaccessible areas where surgery is difficult, day care procedure and cost effective.

Colouring of COVID-19 Affected Region Based on Fuzzy Directed Graphs

Graph colouring is the systemof assigning a colour to each vertex of a graph. It is done in such a way that adjacent vertices do not have equal colour. It is fundamental in graph theory. It is often used to solve real-world problems like traffic light signalling, map colouring, scheduling, etc. Nowadays, social networks are prevalent systems in our life. Here, the users are considered as vertices, and their connections/interactions are taken as edges. Some users follow other popular users' profiles in these networks, and some don't, but those non-followers are connected directly to the popular profiles. That means, along with traditional relationship (information flowing), there is another relation among them. It depends on the domination of the relationship between the nodes. This type of situation can be modelled as a directed fuzzy graph. In the colouring of fuzzy graph theory, edge membership plays a vital role. Edge membership is a representation of flowing information between end nodes of the edge.Apart fromthe communication relationship, theremay be some other factors like domination in relation. This influence of power is captured here. In this article, the colouring of directed fuzzy graphs is defined based on the influence of relationship. Along with this, the chromatic number and strong chromatic number are provided, and related properties are investigated. An application regarding COVID-19 infection is presented using the colouring of directed fuzzy graphs
