Stem rust caused by Puccinia graminis f.sp. tritici and stripe rust caused by Puccinia striiformis are the most destructive wheat rust diseases when environment conditions are favorable in regions where wheat crops are grown. An early prediction mechanism can play a great role in forecasting the occurrence of the rust disease. It assists proactive control and early decision making. However, in the absence of prediction mechanism of wheat rust disease hurried wheat production yield loss more. Hen...

In the recent years, Mobile Ad-Hoc Wireless Networks (MANET) have played a key role in communication system. It is a self-configured and infrastructure-less network. It is used in different application areas like disaster recovery operations, hospitals and agricultural sectors. However, there are a lot of problems that limit the performances of this network for significantly achieving its roles in different areas. To overcome these problems, this paper enhances the performances of MANET in wirel...

An alternative approach for conducting tests of multi-choice format, is the e-Examination Platform or simply a Computer based Test (CBT). The CBT is necessary considering the large population of students enrolled in Nigerian Secondary and Higher Institutions of learning. Furthermore, the student size and the unique nature of some departmental courses hinder its total implemen-tation. This paper investigates the challenges attribut ...

The limited lifetime
period of wireless nodes of Ad hoc networks due to their battery power, has
been forming a significant issue and concern for researchers. To solve this
previous related research has ignored low energy nodes regardless of its total
residual energy without ignoring the importance of hop count value for
selecting paths in forwarding decision. This paper aims at finding
and proposing a new path selection metric th ...

In this article, we present a new method based on the securisation of an IPv6 (Internet Protocol version 6) address obtaining with the SLAAC (Stateless Address Autoconfiguration) method in the domestic network. The particularity of our domestic network is the presence of several Multihoming Internet service providers. The peripherals of the Home Network domain, especially routers are in charge of the re ...

A new PLSGP (potential smokers-light smokers-persistent smokers-giving up smokers-potential smokers) model with birth and death rates on complex heterogeneous networks is presented. Using the mean-field theory, we obtain the basic reproduction number R0 and find that basic reproduction number for constant contact is independent of the topology of the underlying networks. When R0＜1, the smoki ...

In this paper, a new epidemic SEIRS model with time delay on complex networks is proposed. Based
on the mean field theory, the basic reproductive number and equilibriums of the
model are derived. Moreover, the impact of the network topology and time delay
on the basic reproductive number is analyzed. Theoretical analyses indicate
that the basic reproductive numb ...

In this paper, a performance
analysis study for VoIP over mobile wireless ad hoc networks (MANET) is carried
out using OPNET tool. The AODV, DSR, TORA, OLSR, and GRP routing protocols have
been used as candidates to evaluate the impact
of routing on quality of service (QoS) of VoIP application over MANET networks.
Three different queuing mechanisms (FIFO, PQ, and WFQ) have been used also as
nominee of queuing techniques. The VoIP ...

The rumor spreading has been widely studied by scholars. However, there
exist some people who will persuade infected individuals to resist and
counterattack the rumor propagation in our social life. In this paper, a new SICS (susceptible-infected-counter-susceptible) rumor
spreading model with counter mechanism on complex social networks is presented.
Using the ...

In this paper, we present a SARS (susceptible-adopted-removed-susceptible) social information spreading model with
overlapping community structures on complex networks.
Using the mean field theory, the spreading dynamic of the model has been
studied. At first, we derived the spreading critical threshold value and equilibriums. Theoretical results indicate that t ...
