Deep-water offshore drilling vessels, such as a semisubmersible drilling rig, use the
dynamic positioning (DP) system and the thruster-assisted position-mooring system for …

Background: In the literature node localization and energy efficiency are intrinsic problems
often experienced in wireless sensor networks (WSNs). Consequently, various heuristic …

Wireless body sensor networks (WBSNs) plays a vital role in monitoring health conditions of
patients and is a low-cost solution for dealing with several healthcare applications …

Harmony search (HS) and its variants have been found successful applications, however
with poor solution accuracy and convergence performance for high-dimensional (≥ 200) …

Wireless sensor networks unusual capability of sensing, processing and communicating, is
making WSN more promising field in number of applications like health care, military, and …

Wireless sensor networks (WSNs) is a rapidly growing technology. WSNs comprises of
sensor nodes having limited energy as battery powers them. These batteries cannot be …

Maximizing the lifetime is an important issue in the design of applications and protocols for
wireless sensor networks (WSNs). Clustering sensor nodes is an effective topology control …

Wireless sensor networks (WSN) are primarily used for sensing and collecting the
information from environment. This information is sent to base station (BS), where, it is …

This paper proposes an improved variant of the harmony search (HS) algorithm called
HSGS for solving clustering problems. The HSGS generates two new harmonies at each …

As it is the fact that sensors deployed in the field are not accessible after deployment hence
lifetime of the network is directly dependent on residual energy the sensors have …
