The Wireless sensor networks (WSN) is functional in various environments namely surveillance of forest, earth quake monitoring, medical applications etc. This paper tackles with the problem of WSNs with detection of the target with dynamic considerations and random deployment of node. The proposed work explains initial environments of Energy Efficient Distributed Receiver Based Routing Protocol (EEDR)...
in this paper, we have urbanized a fresh sink placement policy in Wireless Sensor Networks (WSNs). We studied the problems in previous sink placement strategies such as RSP, CNP, GOSP, SOSP, CLHM, ISP, and GSP. These previous sink placement strategies are not concerned about dynamicity of the network under consideration. The information about sensor nodes positions is not known beforehand in concerned...
Wireless Sensor Networks (WSNs) are often deployed in remote and hostile areas and because of their limited power and vulnerability, the sensors may stop functioning after sometime leading to the appearance of holes in a network. A hole created by the non-functioning sensors in turn severs the connection between one side and the other side of the network and alternative routes need to be found for...
Routing in Mobile Ad hoc Networks (MANETs) is crucial as the topology changes occur more frequently. The routing protocol associated with network layer should therefore adhere to the change in topology and thereby provide good Quality of Service. As most of the devices involved in MANET are battery operated, routing of packets, playing an important role in energy consumption, arises the need for energy...
The latest mobile devices such as smart phones and tablet PCs, equipped with high resolution interactive screens, highly advanced CPUs, wireless networking and multimedia processing capabilities have become very important in people's daily life. The growth of these devices' popularity has determined an increased interest from shopping malls, theme parks, institutions, convention centre, etc. to deploy...
Sensor nodes of Wireless Sensor Networks (WSNs) are usually powered by non rechargeable exhaustible batteries with limited lifetime duration. As the deployment of these WSNs operates in harsh environments, generally inaccessible and sometimes hostile, the replacement of depleted batteries is not feasible or cumbersome because of the huge number of nodes. Therefore, sensor nodes have to ensure their...
A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes a scheme to improve existing on-demand routing protocols by introducing the power aware virtual node scheme in whole scenario. The scheme establishes...
Energy management has become one of the main hurdles in the quest for autonomous and reliable Wireless Sensor Networks (WSN). This paper examines the emerging problem of increasing network availability by recharging, replacing or redeploying depleted sensors with the help of mobile entities. When mobility becomes a sensor's attribute and service stations are static, we propose passive vs. pro-active...
A recent trend in ad hoc network routing is the reactive on-demand philosophy where routes are established only when required. Most of the protocols in this category, however, use single route and do not utilize multiple alternate paths. This paper proposes an analytical analysis of energy parameters, their usage and their evaluation in ad hoc networks. The scheme is incorporated with the AODV and...
The next generation communication systems will provide high quality multimedia services in a flexible and efficient manner. As an extension of next generation networks, Mobile Ad Hoc Networks (MANETs) have attracted significant attention amongst researchers. Nodes in a MANET have limited battery power. Hence, ad hoc routing protocols ought to be energy conservative to support real-time multimedia...
Most sensor networks require application-specific network-wide performance guarantees, suggesting the need for global and flexible network optimization. The dynamic and nonuniform local states of individual nodes in sensor networks complicate global optimization. Here, we present a cross-layer framework for optimizing global power consumption and balancing the load in sensor networks through greedy...
