Factors such as cons...

A Wireless Sensor Network applications include a set of isolated urban areas deployed with sensor nodes for monitoring environmental parameters. In urban area vehicles viz (buses, vans, cars, etc) are used as to carry the mobile sinks to collect the sensory data effectively which provides the ideal infrastructure. Existing approach include only single hop transfer, which transfer data directly ...

Wireless Sensor Networks (WSN) popularity has increased tremendously in recent time due to growth of semiconductor and VLSI technology. WSN has the potentiality to connect the physical world with the virtual world by forming a network of sensor nodes. Here, sensor nodes are usually battery-operated devices, which operate in harsh environment. So, hence energy saving of sensor nodes is a major p...

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 ...

Wireless detector nodes are deployed on a battleground and organize themselves in an exceedingly largescale ad-hoc network. Traditional routing protocols don't take into consideration that a node contains solely a restricted provided energy. Optimal routing tries to maximise the length over that the sensing task is performed, however needs future knowledge. The proposed work use to simulate sen...

Uneven energy consumption is an inherent problem in wireless sensor networks characterized by multihop routing and many-to-one traffic pattern. Such unbalanced energy dissipation can significantly reduce network lifetime. In this paper, we study the problem of prolonging network lifetime in large-scale wireless sensor networks where a mobile sink gathers data periodically along the predefined p...

Wireless energy transfer is used to fundamentally address energy management problems in Wireless Rechargeable Sensor Networks (WRSNs). In such networks mobile entities traverse the network and wirelessly replenish the energy of sensor nodes. In recent research on collaborative wireless charging, the mobile entities are also allowed to charge each other. In this work, we enhance the collaborativ...

Mobile sinks wireless sensor networks (MSWSNs) are composed of a large number of densely deployed sensor nodes with some data collection mobile devices (such as PDA or notebook) to collect sensing data from the networks. In this paper we highlight the most important work we found in the literature related to this topic, and we present our new routing protocol for MSWSN. Among the research work ...

In Mobile Wireless Sensor Networks (MWSNs), nodes are supplemented with implicit or explicit mechanisms that enable these devices to move in space. The packet loss is one of the main challenges that occur due to mobility of such networks and it comes in parallel with energy consumption. Moreover, data collection with the minimum energy consumption is one of the important issues in wireless sens...

Wireless Sensor Networks(WSNs) is a set or collection of different distributed nodes which is measure(Capture)the environmental changes like Temperature, Sound, Pressure from the environmental area. Data packets or information is sending from one location to another location i.e. Source to the Destination. Sensor nodes are capable for the information gathering and communication between other no...
