abstract lateral intake is a hydraulic structure which is used for diversion of some portion of water from a river for the purpose of irrigation, storage and industrial. most of lateral intakes from canal are installed at canal with inclined banks which has not received the attention of the researchers in the past. since the flow discharge and sediment which enters the intake canal depends on t...

quorum-based power saving (qps) protocols allow “asynchronous” wireless hosts, operating in a multi-hop ad-hoc network, to tune to the low power mode conceived in ieee 802.11 mac standard. qps schemes guarantee that the wake-up schedule for every two neighboring hosts would ultimately overlap within a bounded latency so as to be able to accomplish their reciprocal “unicast” communications. a ma...

Geocasting is a mechanism to disseminate data messages within a certain geographical region. Since packet forwarding is based on the location information of nodes, it is known to reduce the path maintenance cost significantly. The geocasting can be suitable for several applications in tactical ad hoc networks, such as an event to alarm enemy’s missile attack, guerilla appearance, or local weath...

A wireless detector network gathering an outsized range of small sensor nodes which is capable to perform native computations supported by gathering sensor data and communicating with alternative sensor nodes within the network. The fault node recovery (FNR) algorithm, grade diffusion algorithm combined with the genetic algorithm finds the dead node and shortest path with the help of following ...

This study proposes a location-based hybrid routing protocol to improve data packet delivery and to reduce control message overhead in mobile ad hoc networks. In mobile environments, where nodes move continuously at a high speed, it is generally difficult to maintain and restore route paths. Therefore, this study suggests a new flooding mechanism to control route paths. The essence of the propo...

Using multiple channels in wireless sensor networks helps increase the overall throughput and avoid interferences. In addition, introducing multi-interface nodes further helps in increasing the packet delivery rate for those specific nodes. In this paper, we evaluate a channel allocation method based on neighborhood discovery up to 3 hops and a hybrid MAC protocol designed for high data rate wi...

Wireless Mesh Networks (WMNs) are a promising technology that could revolutionize the way wireless network access is provided. We allocate the available bandwidth in wireless mesh network to reducing the energy consumption of a user using the AODV protocol. the AODV protocol to reducing energy consumption using the improving parameters are throughput, end to end delay, network overhead, energy ...

As the nodes are self resourced in ad hoc networks, the denial of service as relay hop by any node is frequent. This is due to resource levels of that node are lower than the threshold, in another act the node may be irrational and selfish. In such cases the irrational or selfish nodes leads to attacks such as black-hole and grey-hole and also causes the poor routing performance under metrics s...

A mobile ad hoc network (MANET) consists of mobile nodes that are capable of communicating with each other in multihop trend without centralized control and fixed based station. Multipath Routing permits the flow of data from source to destination over multiple paths through the network. In ad hoc network, basic goal of routing protocols is to efficiently establish a route between the pair of n...

Abstract— This paper investigates the benefits and impacts of using directional antennas for multicast communications in ad hoc networks. In terms of signal reception, directional antennas have shown considerable improvement in the performance of all aspects over omni-directional antennas, especially over dense networks with heavy traffic load. In addition, we have found that transmitting multi...
