In mission critical applications, all critical points (CPs) are to be monitored effectively. Even a single node failure in the Wireless Sensor Network (WSN) may cause coverage hole, reducing the lifetime of the network. The sensor has nonrechargeable battery which makes energy supervision inevitable. The proposed Energy Efficient Coverage based Artificial Bee Colony Optimization (EEC-ABC) appro...

Recently, Wireless Sensor Network has captured the attention of academic and industrial research communities. One of the reasons is that Wireless Sensor Network has diverse applications and domains such as environment protection, battlefield monitoring, traffic control, etc. The central problem of a Wireless Sensor Network is the Coverage Problem that poses the question of how the set of sensor...

The Coverage Control Technology is the one of the basic technologies of wireless sensor network, and is mainly concerned about how to prolong the network lifetime on the basis of meeting user’s perception demand. Among this technology, localized area coverage algorithm in the study of area coverage technology is gradually attracting wide attention, for its less traffic and lower single-node com...

Providing field coverage is a key task in many sensor network applications. In certain scenarios, the sensor field may have coverage holes due to random initial deployment of sensors; thus, the desired level of coverage cannot be achieved. A hybrid wireless sensor network is a cost-effective solution to this problem, which is achieved by repositioning a portion of the mobile sensors in the netw...

WIMAX relay station mesh network has been approved by IEEE 802.16j as a standard to provide a highly data rate transmission , the RS was implemented to extend the coverage zone of the BS, for instance the MSs previously were out of the coverage of the BS they become in the coverage of the RS, therefore these MSs can have Admission control from the BS through the RS. This paper describe a proble...

One of the current trends of the wireless communication is the underwater communication .The two most fundamental problems in underwater sensor network are sensing coverage and network connectivity. The coverage problem reflects how well a sensor network is tracked or monitored by sensors. An underwater wireless sensor networks is the emerging field that is having the challenges in each field s...

Network coverage is one of the fundamental requirements of any business of a service provider. Mobile operators are expected to deploy base stations in an effective way in order to cover most of the residential areas of a particular country. Improved network coverage leads to increase total revenue, provide end users with enhanced Quality of Services (QoS) anytime anywhere, and play vital role ...

Efficient network coverage and connectivity are the requisites for most Wireless Sensor Network deployments, particularly those concerned with area monitoring. The Coverage Control Technology is one of the basic technologies of wireless sensor network, and is mainly concerned about how to prolong the network lifetime on the basis of meeting users’ perception demand. To optimize wireless sensor ...

In a randomly deployed and large scale wireless sensor network, coverage-redundant nodes consume much unnecessary energy. As a result, turning off these redundant nodes can prolong the network lifetime, while maintaining the degree of sensing coverage with a limited number of on-duty nodes. None of the off-duty eligibility rules in the literature, however, are sufficient and necessary condition...

A wireless sensor network (WSN) is a composed group of a small tiny battery-equipped device capable of sensing, communication and computation which can be scattered over a vast region for the purpose of detecting or monitoring region perfectly. Sensing coverage and network connectivity are two of the most fundamental problem in WSNs. In WSN is usually defined as a measure of how well the sensin...
