With fully directional communications, nodes must track the positions of their neighbors so that communication with these neighbors is feasible when needed. Tracking process introduces an overhead, which increases with the number of discovered neighbors. The overhead can be reduced if nodes maintain only a subset of their neighbors; however, this may increase the length of paths between node pairs in the network. In this work, we study the tradeoffs between node degree and path stretch. We first design a topology control algorithm to optimize t ....etc

XTC: A Practical Topology Control Algorithm for Ad-Hoc Networks
Abstract: The XTC AD-HOC network topology control algorithm introduced shows three main advantages over previously proposed algorithms. First, it is extremely simple and strictly local. Second, it does not assume the network graph to be a unit disk graph; XTC proves correct also on general weighted network graphs. Third, the algorithm does not require availability of node position information. Instead, XTC operates with a general notion of order over the neighbors' page link quali ....etc

Bandwidth Efficient Video Multicasting in Multiradio Multicellular Wireless Networks

Abstract—

In this paper, we propose a new mechanism to select the cells and the wireless technologies for layer-encoded video multicasting in the heterogeneous wireless networks. Different from the previous mechanisms, each mobile host in our mechanism can select a different cell with a different wireless technology to subscribe each layer of a video stream, and each cell can deliver only a ....etc

Abstract
Network wide broadcasting in Mobile Ad Hoc Networks(MANET) provides important control and route establish-ment functionality for a number of unicast and multicastprotocols. We present an overview of the recent progressof broadcasting and multicasting in wireless ad hoc net-works. We discuss two energy models that could be usedfor broadcast: one is non-adjustable power and one is ad-justable power. If the power consumed at each node isnot adjustable, minimizing the total power used by a re-liable broadcast tree is equivalent to ....etc

SECURE WIRELESS SENSOR NETWORKS - ROBUST OF WSN ATTACKS AND SECURE LOCALIZATION SCHEME
ABSTRACT
The application of wireless sensor networks (WSN), sensors are deployed un-tethered in hostile environments. For location aware WSN applications, it is essential to ensure that sensors can determine their location, even in the presence of malicious adversaries. Our paper mainly projects the problem of enabling sensors of WSN to determine their location in an un-trusted environment. The localization schemes based ....etc

A Self-Repairing Tree Topology Enabling Content-Based Routing in Mobile Ad Hoc Networks

Aim:
The mainstay of this project is to achieve the repair strategies to tolerate the frequent topological reconfigurations in Mobile AdHoc Networks by Content Based Routing (CBR) using a protocol namely COMAN.

CONTENT BASED ROUTING (CBR) differs from classical routing in that messages are addressed based on their content instead of their destination. In conventional systems, the sender explicitly specifies the intended message recipient ....etc

Abstract—Topology engineering concerns with the problem of automatic determination of physical layer parameters to form a network with desired properties. In this paper, we investigate the joint power control, channel assignment, and radio interface selection for robust provisioning of page link bandwidth in infrastructure multiradio multichannel wireless networks in presence of channel variability and external interference. To characterize the logical relationship between spatial contention constraints and transmit power, we formulate the jo ....etc
