In this paper, the Hepatitis B Virus (HBV) infectious model with Cytotoxic T-Lymphocyte (CTL) response delay and its effect on the stability of equilibrium has been investigated. The boundedness and non-negativity solutions of the proposed model were verified. The local stability of virus-free equilibrium and the infected equilibrium were determined by the basic reproduction number R0. Further, the existence of Hopf bifurcation at the infected equilibrium of CTL response was also observed. Using different set of parameters, the empirical findings in the study are shown with numerical simulations.

A Secured and Associated Congestion Hybrid AODA Protocol in WSN Networks using MANETS


European Journal of Molecular & Clinical Medicine, 2020, Volume 7, Issue 4, Pages 369-375

Ad-Hoc Network is an independent arrangement of portable Hubs or nodes associated by remote associations. Hubs or nodes are free to travel, every now and again change their position and sort out themselves into a system. Hubs or nodes contain remote transmitter and beneficiary that permit them to participate in remote system. Hubs or nodes in MANET having double conduct, they go about as switches just as registering gadgets. Constrained transmission capacity and changing geography results the issue of Congestion in MANETs. Recognizing Congestion is troublesome in remote system, since there might be a few purposes for dropping of parcels. Specially appointed system is characterized as the system wherein the clients speak with one another by shaping a transitory system with no concentrated organization. Here every hub demonstration both as a host just as a switch. They have profoundly deployable, dynamic and self-configurable geographies. Different steering conventions are characterized for MANETs. Congestion and security issues are both solved in this paper using bloom filter and congestion aware protocol hybrid combination in AODV protocol. The results show better energy, PDR, throughput and high speed of the wireless sensor network.
