The exponential rise in wireless communication demands and allied applications have revitalized academia-industries to develop more efficient routing protocols. Wireless Sensor Network (WSN) being battery operated network, it often undergoes node death-causing pre-ma...

Increasing data on web has resulted in increasing challenge for keyword query routing. Top k routing is an approach used for keyword query search. Keyword query routing work efficiently for one or two keyword but its efficiency drastically reduces while handling multiple keywords. Our approach is to increase the efficiency even for multiple keyword querying. We are going to follow keyword-eleme...

At the present stage wireless sensor network exists some deficiencies such as finite energy, limited communication capability, multi-hop routing and dynamic topology. In addition too many nodes which are distributed intensively influence also performance of wireless sensor network. Besides distributed optimization problem always impact to efficiency of the network. For data processing and routi...

With the capacity of achieving spectrum efficient wireless communications, cognitive radio enabled Advanced Metering Infrastructure (CR-AMI) networks are expected to enhance the efficiency and practicability of future smart grids. CR-AMI networks which has been recognized as a fundamental component of the smart grid ecosystem, are practically utilized as a static multi-hop wireless mesh network...

Hybrid wireless networks support both Mobile Adhoc network (MANET) and Infrastructure wireless network. An efficient data routing protocol is important to improve the network efficiency. This efficient data routing protocol support hybrid wireless networks for high capacity and scalability. In this paper, we proposed Distributed Three-Hop Routing (DTR) protocol to improve the capacity of Hybrid...

This paper describes the concept of routing in wireless sensor networks. Routing algorithm provides reliable path from source to destination. Energy efficiency is main constraint in Wireless Sensor Networks. For improving life time and energy consumption various routing algorithms have been proposed. In this paper describe the hierarchical routing techniques. Hierarchical routing includes tree ...

Generally, the radio channel quality of a wireless sensor network (WSN) is unstable in harsh environment. For instance, in maritime search and rescue, the nodes of WSN move dynamically, the topology changes with respect to the time and the communication link changes frequently as well. What is more, the given communication distance of nodes can limit the efficiency of routing. In view of these ...

We consider market rules for transferring IP addresses, numeric identifiers required by all computers connected to the Internet. Transfers usefully move resources from lowest to highest-valuation networks, but transfers tend to cause socially costly growth in the Internet’s routing table. We propose a market rule that avoids excessive trading and comes close to achieving social efficiency. We a...

In this paper, we investigate how to design energy-efficient localized routing in a large-scale three-dimensional (3D) wireless network. Several 3D localized routing protocols were proposed to seek either energy efficiency or delivery guarantee in 3D wireless networks. However, recent results [1, 2] showed that there is no deterministic localized routing algorithm that guarantees either deliver...
