WMSNs are extensively used in various fields such as environmental monitoring, survellience, national security and health care. Wireless networks are composed of sensor nodes having capability of sensing environmental conditions, sink node and connected via internet to remote controller. Maximun coverage is one of the basic objective of WMSNs. So the current document presents review as well as comparision...
Mobile Ad hoc Networks (MANETs) are the networks of mobile nodes which do not require any access points to communicate with each other within the radio range. Due to their applications in situations such as emergencies, crisis management, military and healthcare, message security is of paramount importance in mobile ad-hoc networks. The paper proceeds with a brief introduction of MANETs followed by...
In this paper we present a data collection scheme using mobile sink in wireless sensor and actor networks (WSAN). In order to improve the performance of WSAN, mobile sink is introduced. The mobile sink is able to move through the monitoring area, collect the sensed data from the sensor nodes in the radio transmission range. Once the data from all sensors are collected, the mobile sink returns to the...
In this paper, we address the issue of coverage in a hybrid wireless sensor network with regard to energy constrains. Since battery resources of sensors is limited, it is important to design energy-efficient algorithms. Limiting the moving distance of mobile sensors and using the minimum number of working sensor nodes are good ways of conserving energy resources in sensors. In our algorithm, maximum...
Recent work has shown that sink mobility along a constrained path can improve the energy efficiency in wireless sensor networks. However, due to the path constraint, a mobile sink with constant speed has limited communication time to collect data from the sensor nodes deployed randomly. This poses significant challenges in jointly improving the amount of data collected and reducing the energy consumption...

Coverage is one of the fundamental issue is wireless sensor networks so k-coverage that means a target location is sensing by k sensor is important, but in WSN low energy consuming is desire so we use off-duty operation. We propose a method to k-coverage the field. Our target problem is NP-hard. So, we propose a genetic algorithm (GA) to find solution that is a near optimal solution. In our method,...
Sensing coverage and network connectivity are two of the most fundamental problems in wireless sensor networks.

Accomplishing data collection in WSNs by mobile elements (MEs) can reduce the amount of multi-hop communications in the network, which will decrease the energy consumption of sensors and prolong network lifetime. However, this may result in unacceptable data collection latency. The problem can be alleviated by reducing the traveling distance of the MEs with a genetic algorithm (GA) implementation...

This poses significant challenges in simultaneously improving the amount of data collected and reduction in energy consumption...
Energy in WSNs can be significantly saved by integrating a mobile BS, which on the other hand may impose the network an unacceptable latency. In this paper, we overcome this problem by making the path of the mobile BS as short as possible. Our method mainly consists of three steps. First, we construct a virtual network from which to choose the location that the BS must arrive. Next, we apply a weighting...
Energy consumption is critical and the processing ability and memory of sensor nodes are limited in wireless sensor networks.
