Generally the mobile nodes are battery operated which make energy a scarce resource in MANETs. Efficient utilization of the energy is one of the most crucial issues in MANETs. Energy needs to be optimally utilized so that the nodes can perform their functionality satisfactorily. A node in MANET is a router as well, it could be difficult for a mobile node to(More)
In mobile ad hoc networks, the movement of the mobile nodes is one of the important characteristics because it can affect the performance of the routing protocol. The mobility pattern directly influences when communication links between nodes are established or broken, which is associated with the network topology. In this paper, the impact of the different(More)
Due to mobility constraints and high dynamics, routing is a more challenging task in VANETs. In this work, we evaluate the performance of the routing protocols in vehicular network environment. The objective of this work is to assess the applicability of these protocols in different vehicular traffic scenarios. Both the position-based and topology-based(More)
Vehicular Ad Hoc Networks (VANETs) are a new communication paradigm that enables the communication between vehicles moving at high speeds on the roads. This has opened doors to develop several new applications like traffic engineering, traffic management, dissemination of emergency information to avoid hazardous situations and other user applications.(More)
Superficial mycoses caused by dermatophytic fungi such as Trichophyton rubrum represent the most common type of worldwide human infection affecting various keratinized tissues in our body such as the skin, hair, and nails, etc. The dermatophytic infection is a significant public health threat due to its persistent nature and high recurrence rates, and thus(More)
Microorganisms have provided a bounty of bioactive secondary metabolites with very exciting biological activities such as antibacterial, antifungal antiviral, and anticancer, etc. The present study aims at the optimization of culture conditions for improved antimicrobial production of Paenibacillus elgii obtained from Wayanad forest of Western Ghats region(More)
A Pseudomonas aeruginosa strain, RRLJ 04, and a Bacillus cereus strain, BS 03, were tested both individually and in combination with a Rhizobium strain, RH 2, for their ability to enhance plant growth and nodulation in pigeon pea (Cajanus cajan L.) under gnotobiotic, greenhouse and field conditions. Both of the rhizobacterial strains exhibited a positive(More)
In this paper, hybrid chemical reaction based optimization (HCRO) is implemented to solve combined heat and power economic dispatch (CHPED) problem. The CHPED problem is a challenging non-convex and non-linear optimization problem. The effect of valve-point in cost function considered with adding an absolute sinusoidal term to conventional polynomial cost(More)
