Wireless sensor networks (WS s), made of collection of small, cheap, low power sensors, have diverse applications in several domains of life. Most of their applications demand for spatial position of sensors. Beacon nodes which already know their location are mostly used to help other sensor nodes to locate their position. However localization of sensors in a hostile environment is a crucial is...

Software testing is one of the most challenging and arduous phase of software development life cycle (SDLC) which helps in determining the software quality. Code coverage is a widely used testing paradigm, which describes the degree to which the code has been tested. Aim of the current paper is to propose an optimised code coverage algorithm with the help of an emerging technique, i.e., intelli...

In recent years a new type of wireless networks named wireless mesh networks has drawn the attention of researchers. In order to increase the capacity of mesh network, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi channel wireless mesh networks. Therefore, the main challenge of these networks is how to properly assign the channels to the radios. O...

Applying trust in Wireless Sensor network (WSN) is an emerging area where researchers are engrossed in developing novel design archetype to address the security issues. Security plays an important role in WSN where trustworthy sensor node turns into a untrustworthy one because of hardware and software faults. Aim of the paper is to propose an optimized path coverage algorithm with the help of a...

In this paper we study the routing security issues of MANETs, we propose an algorithm to detect malicious nodes based on intelligent water drops algorithm and examine "routing modification attack" problem that can easily be exploited against the MANETs. We also propose a solution for this problem and examine security issues related to proactive routing protocols for MANETs. This could be achiev...

This paper proposes a novel optimization algorithm inspired by water flowing and shaking behaviors in a vessel. Water drops in our algorithm flow to the gradient descent direction and are sometimes shaken for getting out of local optimum areas when most water drops fall in local optimum areas. These flowing and shaking operations allow our algorithm to quickly approach to the global optimum wit...

nowadays, economic load dispatch between generation units with least cost involved is one of the most important issues in utilizing power systems. in this paper, a new method i.e. water cycle algorithm (wca) which is similar to other intelligent algorithm and is based on swarm, is employed in order to solve the economic load dispatch problem between power plants. wca is used to solve complicate...
